Li K, Zhang L, Zhou F, Yang K, Zhan M, Su Y, Wu D, Xie B. Revealing mechanisms of NH 3 and N 2O emissions reduction in the rapid bio-drying of food waste: Insights from organic nitrogen composition and microbial activity. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 938:173353. [PMID: 38795999 DOI: 10.1016/j.scitotenv.2024.173353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 05/15/2024] [Accepted: 05/17/2024] [Indexed: 05/28/2024]
Abstract
Inevitably, aerobic biological treatment processes generate emissions of ammonia (NH3) and greenhouse gas (GHGs) emissions, especially nitrous oxide (N2O). The rapid bio-drying process (RBD) for food waste (FW) alleviates issues arising from its substantial growth. However, its emissions of NH3 and N2O remain unknown, and the correlation with nitrogen components in the substrate remains unclear, significantly impeding its widespread adoption. Here, the nitrogen loss and its mechanisms in RBD were investigated, and the results are as follows: The total emission of NH3 and N2O were1.42 and 1.16 mg/kg FW (fresh weight), respectively, achieving a 98 % reduction compared to prior studies. Structural equation modeling demonstrates that acid ammonium nitrogen (AN) decomposition chiefly generates NH3 in compost (p < 0.001). Strong correlation (p < 0.001) exists between amino acid nitrogen (AAN) and AN. In-depth analysis of microbial succession during the process reveals that the enrichment of Brevibacterium, Corynebacterium, Dietzia, Fastidiosipila, Lactobacillus, Mycobacterium, Peptoniphilus, and Truepera, are conducive to reducing the accumulation of AN and AAN in the substrate, minimizing NH3 emissions (p < 0.05). While Pseudomonas, Denitrobacterium, Nitrospira, and Bacillus are identified as key species contributing to N2O emissions during the process. Correlation analysis between physicochemical conditions and microbial succession in the system indicates that the moisture content and NO3- levels during the composting process provide suitable conditions for the growth of bacteria that contribute to NH3 and N2O emissions reduction, these enrichment in RBD process minimizing NH3 and N2O emissions. This study can offer crucial theoretical and data support for the resource utilization process of perishable organic solid waste, mitigating NH3 and GHGs emissions.

Mechanisms for more efficient antibiotics and antibiotic resistance genes removal during industrialized treatment of over 200 tons of tylosin and spectinomycin mycelial dregs by integrated meta-omics. BIORESOURCE TECHNOLOGY 2024; 401:130715.

Abstract
To mitigate the environmental risks posed by the accumulation of antibiotic mycelial dregs (AMDs), this study first attempted over 200 tons of mass production fermentation (MP) using tylosin and spectinomycin mycelial dregs alongside pilot-scale fermentation (PS) for comparison, utilizing the integrated-omics and qPCR approaches. Co-fermentation results showed that both antibiotics were effectively removed in all treatments, with an average removal rate of 92%. Antibiotic resistance gene (ARG)-related metabolic pathways showed that rapid degradation of antibiotics was associated with enzymes that inactivate macrolides and aminoglycosides (e.g., K06979, K07027, K05593). Interestingly, MP fermentations with optimized conditions had more efficient ARGs removal because homogenization permitted faster microbial succession, with more stable removal of antibiotic resistant bacteria and mobile genetic elements. Moreover, Bacillus reached 75% and secreted antioxidant enzymes that might inhibit horizontal gene transfer of ARGs. The findings confirmed the advantages of MP fermentation and provided a scientific basis for other AMDs.

Abstract
Leachate leakage poses a serious environmental risk to the safety of surrounding soils and groundwater. A much faster approach to reflect landfill leakage is the premise to mitigate the ecological risk of landfills. In this study, two landfills (BJ and WZ) were selected to investigate the leaching characteristics of various pollutants along the vadose soil depths. The physiochemical properties of underlying soils including NO3--N, NO2--N, NH4+-N, OM, TN, EC and Cl- exhibited a typical leaching dynamic along the depths. Among them, TN, NH4+-N, OM, NO3--N, and EC might be used as characteristic pollutants to evaluate the leachate leakage issues in landfilled sites. The genera Thiopseudomonas, Acinetobacter, Pseudomonas, and Hydrogenispora dominated in underlying soils. Compared to BJ samples, a more diverse and active microbiome capable of carbon and nitrogen cycles was observed in WZ samples, which was mainly ascribed to nutrients and elements contained in different types of soils. Among the environmental factors, nitrogenous compounds, SO42-, pH and EC had significant effects on the microbial community structures in the underlying soils. The relative abundances of Hydrogenispora and Caldicoprobacter might be used as characteristic microorganisms to evaluate the leachate leakage issues in landfilled sites. These results provided a deep insight into effects of leachate leakage in underlying soils, especially the pollutants vertical distribution and the corresponding microbial community structures.

Abstract
Electrolytic oxygen aerobic composting (EOAC) is an effective treatment with greater technical superiority and cost advantages for organic solid waste using in situ electrolytic oxygen as a feasible strategy to replace conventional aeration. However, the unclear effects of distribution and variation of in situ electrolytic oxygen on compost maturation in different depth zones of EOAC need further exploration. This study demonstrated that the humification of organic matter was faster at the bottom than in the middle and at the top. The main reason was that the higher oxygen content and lower moisture content in the bottom promoted microbial degradation and heat production, resulting in higher temperatures. The microbial analysis showed that the abundance of typical thermophilic bacteria (such as Cerasibacillus, Lactobacillus, and Pseudogracilibacillus) that could promote compost maturation was higher at the bottom than in the middle and at the top. The finding provided in-depth molecular insights into differentiated humification from bottom to top in EOAC and revealed its further practical engineering applications.

Bacterial dynamics for gaseous emission and humification during bio-augmented composting of kitchen waste with lime addition for acidity regulation.

Abstract
This study investigated the impacts of lime addition and further microbial inoculum on gaseous emission and humification during kitchen waste composting. High-throughput sequencing was integrated with Linear Discriminant Analysis Effect Size (LEfSe) and Functional Annotation of Prokaryotic Taxa (FAPROTAX) to decipher bacterial dynamics in response to different additives. Results showed that lime addition enriched bacteria, such as Taibaiella and Sphingobacterium as biomarkers, to strengthen organic biodegradation toward humification. Furthermore, lime addition facilitated the proliferation of thermophilic bacteria (e.g. Bacillus and Symbiobacterium) for aerobic chemoheterotrophy, leading to enhanced organic decomposition to trigger notable gaseous emission. Such emission profile was further exacerbated by microbial inoculum to lime-regulated condition given the rapid enrichment of bacteria (e.g. Caldicoprobacter and Pusillimonas as biomarkers) for fermentation and denitrification. In addition, microbial inoculum slightly hindered humus formation by narrowing the relative abundance of bacteria for humification. Results from this study show that microbial inoculum to feedstock should be carefully regulated to accelerate composting and avoid excessive gaseous emission.

JOURNAL OF ENVIRONMENTAL MANAGEMENT 2022; 320:115772. [PMID: 35944317 DOI: 10.1016/j.jenvman.2022.115772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 07/05/2022] [Accepted: 07/14/2022] [Indexed: 06/15/2023]
Abstract
Palm oil mill waste has a complex cellulosic structure, is rich in nutrients, and provides a habitat for diverse microbial communities. Current research focuses on how the microbiota and organic components interact during the degradation of this type of waste. Some recent studies have described the microbial communities present in different biodegradation processes of palm oil mill waste, identifying the dominant bacteria/fungi responsible for breaking down the cellulosic components. However, understanding the degradation process's mechanisms is vital to eliminating the need for further pretreatment of lignocellulosic compounds in the waste mixture and facilitating the commercialization of palm oil mill waste treatment technology. Thus, the present work aims to review microbial community dynamics via three biological treatment systems comprehensively: composting, vermicomposting, and dark fermentation, to understand how inspiration from nature can further enhance existing degradation processes. The information presented could be used as an umbrella to current research on biological treatment processes and specific research on the bioaugmentation of indigenous microbial consortia isolated during the biological degradation of palm oil mill waste.

Abstract
Total solid content (TS) is an important factor for biogas production during anaerobic digestion. In this study, we explored the influence of different TS (5% wet, 15% semi-solid and 25% solid state) on the relative cumulative methane production (RCMP) during anaerobic co-digestion of chicken manure with corn straw. Results showed that total ammonium nitrogen and free ammonia nitrogen concentration increased with the increase of TS. Ammonium nitrogen in treatments at 15% TS was 2.25-2.76 times as high as that at 5% TS, which was below 3 times. The highest chemical oxygen demand removal and RCMP were obtained in the treatment of 15% TS with a ratio of 2:1 chicken manure: corn straw (based on TS). The RCMP in the treatments of 15% TS were 3.63-4.59 times higher than that of 5% TS based on the volume of substrates. The abundance of Caldicoprobacter improving the degradation of corn straw was significantly positively correlated with the RCMP, and the average abundance of Caldicoprobacter at 15% TS was 8.33 and 7.02 times higher than that at 5% and 25% TS, respectively. Structural equation models analysis suggested that TS significantly impacted the RCMP by indirectly impacting free ammonia nitrogen and microbial abundance. These findings indicated semi-solid state (15% TS) decreased ammonia nitrogen releasing and improved the abundance of Caldicoprobacter, and increased RCMP during anaerobic co-digestion of chicken manure with corn straw.

Abstract
Black soldier fly larvae (Hermetia illucens L. BSFL) bioconversion is a promising biotechnology for food waste treatment. However, the separated residues still do not meet criteria for use as land application biofertilizers. In this work, we investigated a full-scale BSFL bioconversion project to explore features of dissolved organic matter (DOM) and its associated responses of bacterial community succession in residue during secondary composting. Data showed that the concentrations of total nitrogen and ammonium nitrogen decreased by 11.8% and 22.6% during the secondary composting, respectively, while the nitrate nitrogen concentration increased 18.7 times. The DOM concentration decreased by 69.1%, in which protein-like, alcohol-phenol, and biodegradable aliphatic substances were metabolized by bacteria during the thermophilic phase together with the accumulation of humus-like substances, resulting in an increase in the relative concentration of aromatic compounds. The structure of the bacterial community varied at different stages of the bioprocess, in which Bacteroidetes, Actinobacteria, Proteobacteria, and Firmicutes were the dominant bacterial phyla. Lysinibacillus, Pusillimonas, and Caldicoprobacter were found to be key contributors in the degradation and formation of DOM. The DOM concentration (33.4%) and temperature (17.7%) were the prime environmental factors that promoted succession of the bacterial community. Through bacterial metabolism, the structural stability of DOM components was improved during the composting process, and the degrees of humification and aromaticity were also increased. This study depicted the dynamic features of DOM and the associated bacterial community succession in residue during secondary composting, which is conducive with the reuse of BSFL residue as biofertilizer for agriculture.

Abstract
An effective statistical tool for increasing and boosting the production of xylanase and pectinase by Bacillus amyloliquefaciens ADI2 during submerged fermentation (SmF) appears to be the response of surface methodology (RSM) using the central composite design (CCD). Optimum production was achieved under fermentation conditions of a temperature of 28 °C, pH of 8.38, inoculum size of 4% (w/v) and agitation speed of 94 rpm for 48 h. The experimental responses demonstrated a near agreement with the expected responses under optimum conditions of independent variables, suggesting the model’s validity. The optimised CCD model had a 1.34-fold, 159 ± 6 U/mL greater xylanase and 5.96-fold, 205 ± 9 U/mL greater pectinase production than the one factor at a time (OFAT) approach. The production of concurrent enzymes of xylanase–pectinase resulted in a ratio of 1:1.3.

Microbial inoculant addition at up to 0.9% resulted in a diverse bacterial community with more functional bacteria to amend gaseous emission and enhance humification. Microbial inoculation facilitated the enrichment of aerobic bacteria (e.g. the genus Bacillus and Thermobifida) to enhance cellulolysis and ligninolysis to advance organic humification. By contrast, several bacteria, such as the genus Weissella and Pusillimonas were inhibited by microbial inoculation to weaken fermentation and nitrate respiration. As such, bio-augmented composting with 0.9% microbial inoculant reduced the emission of methane by 11-20% and nitrogen oxide by 17-54%. On the other hand, ammonia and hydrogen sulphide emissions increased by 26-62% and 5-23%, respectively, in bio-augmented composting due to the considerable proliferation of the genus Bacillus and Desulfitibacter to enhance ammonification and sulphur-related respiration. Results from this study highlight the need to further develop efficient and multifunctional microbial inoculants that promote humification and deodorization for bio-augmented composting of kitchen waste as well as other carbon and nutrient rich organic wastes.

Different Effects of Thermophilic Microbiological Inoculation With and Without Biochar on Physicochemical Characteristics and Bacterial Communities in Pig Manure Composting. Front Microbiol 2021; 12:746718. [PMID: 34899633 PMCID: PMC8660119 DOI: 10.3389/fmicb.2021.746718] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2021] [Accepted: 10/04/2021] [Indexed: 11/13/2022] Open
Abstract
This study evaluated the effects of thermophilic microbiological inoculation alone (TA) and integrated with biochar (TB) on the physicochemical characteristics and bacterial communities in pig manure (PM) composting with wheat straw. Both TA and TB accelerated the rate of temperature increase during the PM composting. TA significantly reduced total nitrogen loss by 18.03% as opposed to TB which significantly accelerated total organic carbon degradation by 12.21% compared with the control. Firmicutes, Bacteroidetes, Actinobacteria, and Proteobacteria were the major phyla in composting. Variation of the relative abundance of genera depended on the composting period and treatment. The genera Lactobacillus (26.88-46.71%) and Clostridium_sensu_stricto (9.03-31.69%) occupied a superior position in the temperature rise stage, and Bacillus (30.90-36.19%) was outstanding in the cooling stage. Temperature, total nitrogen (TN), and ammonium nitrogen significantly influenced the bacterial phyla composition. TN, water content, and nitrite nitrogen were the main drivers of the bacterial community genera. Furthermore, our results demonstrated that microbiological consortia were resistant to high temperatures and could fix nitrogen for enriched Pseudomonas; however, when interacted with biochar, total organic carbon (TOC) degradation was accelerated for higher bacterial richness and diversity as well as overrepresented Corynebacterium.

Characterization of a thermophilic facultatively anaerobic bacterium Paenibacillus sp. strain DA-C8 that exhibits xylan degradation under anaerobic conditions. J Biotechnol 2021; 342:64-71.

Abstract
The screening, identification, and study of the functional properties of cellulolytic xylanolytic bacteria are crucial for the construction of applicable bioprocesses. The thermophilic facultatively anaerobic, xylanolytic bacterial strain DA-C8 (=JCM34211=DSM111723) exhibiting efficient xylan degradation was newly isolated from compost. Strain DA-C8 completely degraded 1% beechwood xylan within 4 days under anaerobic conditions. By 16S rRNA gene sequence homology and phylogenetic tree analysis, strain DA-C8 was closely related to Paenibacillus cisolokensis and Xylanibacillus composti; however, the average nucleotide identity and digital DNA-DNA hybridization values based on genome information and the carbon source utilization properties indicated that strain DA-C8 belongs to Paenibacillus rather than Xylanibacillus. The gene numbers of xylanase and endoglucanase of strain DA-C8 and X. composti were not different; however, strain DA-C8 had higher abundance of α-L-arabinofuranosidase, β-xylosidase, and β-glucosidase than X. composti. Strain DA-C8 showed decreased xylan and corn hull degradation abilities and growth on xylan medium under aerobic conditions. Quantitative PCR showed high expression of xylan and cellulose degradation genes under anaerobic conditions, but the genes were repressed under aerobic conditions, indicating that strain DA-C8 controls polysaccharide degradation depending on the aeration conditions. Strain DA-C8 is a new species of Paenibacillus with a unique polysaccharide degradation system.

Abstract
Extremophiles are microorganisms that populate habitats considered inhospitable from an anthropocentric point of view and are able to tolerate harsh conditions such as high temperatures, extreme pHs, high concentrations of salts, toxic organic substances, and/or heavy metals. These microorganisms have been broadly studied in the last 30 years and represent precious sources of biomolecules and bioprocesses for many biotechnological applications; in this context, scientific efforts have been focused on the employment of extremophilic microbes and their metabolic pathways to develop biomonitoring and bioremediation strategies to face environmental pollution, as well as to improve biorefineries for the conversion of biomasses into various chemical compounds. This review gives an overview on the peculiar metabolic features of certain extremophilic microorganisms, with a main focus on thermophiles, which make them attractive for biotechnological applications in the field of environmental remediation; moreover, it sheds light on updated genetic systems (also those based on the CRISPR-Cas tool), which expand the potentialities of these microorganisms to be genetically manipulated for various biotechnological purposes.

Symbiotic chitin degradation by a novel anaerobic thermophilic bacterium Hydrogenispora sp. UUS1-1 and the bacterium Tepidanaerobacter sp. GT38. Enzyme Microb Technol 2020; 144:109740. [PMID: 33541575 DOI: 10.1016/j.enzmictec.2020.109740] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2020] [Revised: 11/26/2020] [Accepted: 12/24/2020] [Indexed: 01/21/2023]
Abstract
Chitin is the second most abundant organic compound in nature. Although mesophilic bacteria degrade insoluble chitin, there is a paucity of data describing degradation of insoluble chitin by anaerobic thermophilic bacteria. In this report, we screened cow manure compost for new chitin degradation systems, and identified a chitinolytic bacterial community (CBC) that showed high chitin degradation activity under thermophilic conditions, i.e., 1% (w/v) chitin powder degraded completely within 7 days at 60 °C. Metagenomic analysis revealed that the CBC was dominated by two bacterial genera from Hydrogenispora, an uncultured taxonomic group, and Tepidanaerobacter. Hydrogenispora were abundant in the early-to-mid stages of culturing with chitin, whereas the population of Tepidanaerobacter increased during the later stages of culturing. Strains UUS1-1 and GT38, which were isolated as pure cultures using the roll-tube method with colloidal chitin, N-acetyl-d-glucosamine, and glucose as carbon sources, were found to be closely related to H. ethanolica and T. acetatoxydans, respectively. Strain UUS1-1 readily degraded chitin and is the first anaerobic thermophilic chitinolytic bacterium reported, whereas strain GT38 showed no chitinolytic activity. Based on phylogenetic analysis, UUS1-1 and GT38 should be classified as novel genera and species. Zymogram analysis revealed that UUS1-1 produces at least two chitinases with molecular weights of 150 and 40 kDa. A coculture of UUS1-1 and GT38 degraded crystalline chitin faster with lower accumulation of lactate compared with UUS1-1 alone, indicating that the strains maintained a symbiotic association through assimilation of organic acids in chitin degradation and that strain GT38 consumed end-products to reduce end-product inhibition and enhance the degradation of crystalline chitin.

Abstract
This research aims to study the utilization of waste from power plants, construction and demolition, and agriculture by varying the ratios of flue-gas desulfurization (FGD) gypsum, construction and demolition waste (CDW), and oil palm trunks (OPT) in concrete production. This research used these as the raw materials for the production of concrete bricks of 15 × 15 × 15 cm. There were 12 ratios of concrete brick, fixing 5.5 wt% of FGD gypsum to replace Portland cement and substituting coarse sand with 0 wt%, 25 wt%, 50 wt%, or 75 wt% of CDW, and gravel with 0 wt%, 0.5 wt%, and 1 wt% of OPT. The initial binder:fine aggregate:coarse aggregate ratio was 1:2:4 and the water to cement ratio was 0.5, curing in water at room temperature for 28 days. Then, all concrete brick specimens were tested for compressive strength and water absorption. From the experiment, it was found that the highest compressive strength of concrete brick specimens was 45.18 MPa, which was produced from 5.5% gypsum without CDW and OPT, while 26.84 MPa was the lowest compressive strength obtained from concrete bricks produced from 5.5% FGD gypsum, 75% CDW, and 1% OPT. In terms of usage, all proportions can be applied in construction and building work because the compressive strength and water absorption were compliant with the Thai Industrial Standard TIS 57-2530 and TIS 60-2516.

Abstract
The genome sequences of thermophilic, anaerobic, and cellulolytic-xylanolytic bacterium Herbivorax saccincola strains A7 and GGR1 have recently been determined. Although both strains belong to the same species, A7 is alkaliphilic, non-endospore-forming, and ammonium-assimilating, whereas GGR1 is neutrophilic, endospore-forming, and weak-ammonium-assimilating. To better understand the phenotypic diversity among H. saccincola strains, the genome sequences of A7 and GGR1 were compared. A7 contained three additional genes showing similarity to an alkaline stress-associated ABC-transporter but lacked four endospore formation-associated genes, AUG58543 and AUG58618 (encoding SpoVT), AUG57258 (encoding SpoVS), and AUG58614 (encoding YdhD), all of which were present in GGR1. In addition, A7 contained key ammonia assimilation genes PQQ67145 and PQQ66619, encoding ornithine cyclodeaminase and arginase, respectively, which were absent in GGR1. There was no difference in the number and types of cellulosomal-scaffolding proteins and glycosyl hydrolases between the two strains. However, cellulase and xylanase enzymes from A7 demonstrated greater activity and stability at an alkaline pH compared with those from GGR1, and amino acid substitutions were identified in 11 glycosyl hydrolases from A7. This characterization though comparative genomic analysis provides useful information for understanding the genetic basis of the phenotypic differences between H. saccincola strains isolated from distinct areas and environments.

Abstract
Clostridium thermocellum is a potent cellulolytic bacterium. C. thermocellum strain PAL5, was derived from strain S14 that was isolated from bagasse paper sludge, possesses higher cellulose-degradation ability than representative strains ATCC27405 and DSM1313. In this work, we determined the draft genome sequence of C. thermocellum PAL5. Genomic DNA was used for whole-genome sequencing using the Illumina HiSeq 2500. We obtained 215 contigs of >200 bp (N50, 78,366 bp; mean length, 17,378 bp). The assembled data were subjected to the National Center for Biotechnology Information (NCBI) Prokaryotic Genome Annotation Pipeline, and 3198 protein-coding sequences, 53 tRNA genes, and 4 rRNA genes were identified. The data are accessible at NCBI (the accession number SBHL00000000). Our data resource will facilitate further studies of efficient cellulose-degradation using C. thermocellum.

Abstract
A novel Gram-negative, spore forming, obligately anaerobic, thermophilic, chitin-degrading bacterium, designated UUS1-1T, was isolated from compost on Ishigaki Island, Japan by enrichment culturing using chitin powder as the carbon source. The strain has unique, long, hair-like rod morphological features and exhibits strong degradation activity toward crystalline chitin under thermophilic conditions. Growth of the novel strain was observed at 45-65 °C (optimum, 55 °C) and pH 6.5-7.5 (optimum, pH 7.0). In addition to chitin, the strain utilized several other carbon sources, including N-acetylglucosamine, glucose, galactose, mannose, maltose, cellobiose, fructose and sucrose. The end products of chitin degradation were acetate, lactate, H2 and CO2. Phylogenetic tree analysis based on 16S rRNA gene sequences revealed a clear affiliation of the proposed bacterium to the phylum Firmicutes; the most closely related species were Hydrogenispora ethanolica LX-BT and Desulfotomaculum thermobenzoicum DSM6193T with similarities of 90.4 and 87.8 %, respectively. The G+C content of the genomic DNA was 52.1 mol%. The average nucleotide identity and digital DNA-DNA hybridization values between the genomes of UUS1-1T and H. ethanolica LX-BT were 65.5 and 21.0 %, respectively. The cellular fatty acid composition of the strain was C16 : 0, anteiso-C15 : 0, C14 : 0, C12 : 0 3-OH and dimethyl acetal-C13 : 0. Based on phenotypic, chemotaxonomic and genotypic analysis, strain UUS1-1T represents a novel genus and species, for which the name Capillibacterium thermochitinicola gen. nov., sp. nov. is proposed. The type strain is UUS1-1T (=JCM 33882T=DSM 111537T).

Abstract
Malaysia is the second largest palm oil producer in the world and this industry generates more than 80 million tonnes of biomass every year. When considering the potential of this biomass to be used as a fermentation feedstock, many studies have been conducted to develop a complete process for sugar production. One of the essential processes is the pre-treatment to modify the lignocellulosic components by altering the structural arrangement and/or removing lignin component to expose the internal structure of cellulose and hemicellulose for cellulases to digest it into sugars. Each of the pre-treatment processes that were developed has their own advantages and disadvantages, which are reviewed in this study.
