Miranda SM, Lopes M, Belo I. Exploring the use of hexadecane by Yarrowia lipolytica: Effect of dissolved oxygen and medium supplementation. J Biotechnol 2024; 380:29-37. [PMID: 38128617 DOI: 10.1016/j.jbiotec.2023.12.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 11/30/2023] [Accepted: 12/07/2023] [Indexed: 12/23/2023]
Abstract
This work aimed to evaluate the effect of medium composition and volumetric oxygen transfer coefficient (kLa) on Y. lipolytica growth and production of microbial lipids and enzymes from hexadecane. In the stirred tank bioreactor, increasing kLa from 11 h-1 to 132 h-1 improved the hexadecane assimilation rate, biomass concentration, and lipids synthesis (0.90 g·L-1). A cost-effective hexadecane-based medium supplemented with corn steep liquor and a low amount of ammonium sulfate boosted lipids production up to 2.1 g·L-1, composed of palmitic, palmitoleic, oleic, and linoleic acids. The unsaturated/saturated fraction was dependent on the C/N ratio. Lipids of Y. lipolytica CBS 2075 are promising feedstock for animal feed, food additives, or the biodiesel industry. Simultaneous synthesis of extracellular lipase and protease from hexadecane was observed, which is a new feature that was not previously reported. The highest enzyme activity was obtained at the highest C/N ratio conditions. These results open new perspectives on the application of Y. lipolytica-based cultures for the biotransformation of hexadecane-polluted streams into valuable compounds, fulfilling an interesting strategy towards the circular economy concept.

Dai Y, Li J, Yang X, Wang S, Zhao X, Wang Y, Zhang D, Luo C, Zhang G. New insight into the mechanisms of autochthonous fungal bioaugmentation of phenanthrene in petroleum contaminated soil by stable isotope probing. JOURNAL OF HAZARDOUS MATERIALS 2023; 452:131271. [PMID: 36989785 DOI: 10.1016/j.jhazmat.2023.131271] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 03/21/2023] [Accepted: 03/21/2023] [Indexed: 05/03/2023]
Abstract
Autochthonous fungal bioaugmentation (AFB) is considered a reliable bioremediation approach for polycyclic aromatic hydrocarbon (PAH) contamination, but little is known about its mechanisms in contaminated soils. Here, a microcosm experiment was performed to explore the AFB mechanisms associated with two highly efficient phenanthrene degrading agents of fungi (with laccase-producing Scedosporium aurantiacum GIG-3 and non-laccase-producing Aspergillus fumigatus LJD-29), using stable-isotope-probing (SIP) and high-throughput sequencing. The results showed that each fungus markedly improved phenanthrene removal, and microcosms with both fungi exhibited the best phenanthrene removal performance among all microcosms. Additionally, AFB markedly shifted the composition of the microbial community, particularly the phenanthrene-degrading bacterial taxa. Interestingly, based on SIP results, strains GIG-3 and LJD-29 did not assimilate phenanthrene directly during AFB, but instead played key roles in the preliminary decomposition of phenanthrene though secretion of different extracellular enzymes to oxidize the benzene ring (GIG-3 bioaugmentation with laccase, and LJD-29 bioaugmentation with manganese and lignin peroxidases). In addition, all functional degraders directly involved in phenanthrene assimilation were indigenous bacteria, while native fungi rarely participated in the direct phenanthrene mineralization. Our findings provide a new mechanism of AFB with multiple fungi, and support AFB as a promising strategy for the in situ bioremediation of PAH-contaminated soil.

Abstract
A bioinspired device was fabricated as a sustainable remedial method and its performance as a membrane-enzyme reactor with cyclic ultrafiltration was investigated. The body of the jellyfish-like device was composed of two parts: 1) Jellyfish arms: Mono and co-axial electrospinning have been utilized to synthesize the flexible parts (e.g., multilayer membrane PS-PVDF/PAN/PS-PVDF) used for immobilization of aliphatic degrading enzymes, and 2) Jellyfish tentacles: Hollow fiber membranes were selected for physical immobilization of polycyclic aromatic hydrocarbon (PAH) degrading enzymes. To study the behavior of the membrane/enzyme reactor, the hollow fiber enzyme reactor with pulsation was operated by recycling an enzyme solution to assess ultrafiltration efficiency. A mathematical model was suggested to describe the experimental data obtained in this study to predict the effectiveness of the reactor for PAH removal. When testing the performance of the jellyfish-like device, those equipped with nanofibers with an oil sorption capacity of (10. ±0.7gdilbit/gfiber) were more effective at removing oil particles before they touched the hollow fiber membrane surface. Moreover, the reaction rate measured in a free soluble enzyme and a recirculating immobilized enzyme solution exhibited a slight difference in the kinetic parameter, Km (0.03 and 0.021 mM) due to the internal diffusional resistance. Based on biodegradation studies, a synergistic effect between membrane adsorption, enzymatic degradation, and ultrafiltration was proposed for the removal of anthracene from the column of water.

CHEMOSPHERE 2022; 295:133840.

Abstract
Petroleum degrading enzymes can be used as an alternative way to improve petroleum bioremediation approaches. Alcanivorax borkumensis is an alkane-degrading bacteria that can produce petroleum degrading enzymes such as alkane hydroxylase and lipase. In this study, pilot-scale Alcanivorax borkumensis fermentation was developed for producing large volumes of petroleum degrading enzymes cocktail (∼900 L). Different process conditions, such as inoculum age 72 h and size 4% v/v, temperature 30 ± 1 °C, agitation speed at 150 rpm and, fermentation period 3 days were determined as the optimum for producing alkane hydroxylase and lipase activity. The oxygen transfer capacity was studied for obtaining better bacterial growth and higher enzyme activities in bioreactor process optimization as well as scale-up. Results showed that the maximum values of oxygen mass transfer coefficient (kLa), oxygen uptake rate (OUR), oxygen transfer rate (OTR), alkane hydroxylase, lipase, and cell count were 196.95 h-1, 0.92 mmol O2/L/h, 1.8 mmol O2/L/h, 222.49 U/mL, 325 U/mL, and 8.6 × 1010 CFU/mL, respectively. Compared with the bench-scale bioreactors, the 150 L fermenter showed a better oxygen transfer rate which affected the cell growth that doubled the number and enzymes production that increased. Then, the enzyme cocktail was used for a field test in a diesel source zone using a 5-spot well pattern. The results showed a significant reduction in concentrations of C10 - C50 (from 36% to > 99%) after one injection of enzyme cocktail, mainly for the contaminated soils located in the saturated zone of the unconfined aquifer. This study confirmed the scaling-up ofalkane-degrading enzyme production to an industrial-scale and its application for effective bioremediation of petroleum contaminated sites.

Abstract
Nowadays, nanoparticles (NPs) and nanomaterials (NMs) are used extensively in various streams such as medical science, solar energy, drug delivery, water treatment, and detection of persistent pollutants. Intensive synthesis of NPs/NMs carried out via physico-chemical technologies is deteriorating the environment globally. Therefore, an urgent need to adopt cost-effective and green technologies to synthesize NPs/NMs by recycling of secondary waste resources is highly required. Environmental wastes such as metallurgical slag, electronics (e-waste), and acid mine drainage (AMD) are rich sources of metals to produce NPs. This concept can remediate the environment on the one hand and the other hand, it can provide a future roadmap for economic benefits at industrial scale operations. The waste-derived NPs will reduce the industrial consumption of limited primary resources. In this review article, green emerging technologies involving lignocellulosic waste to synthesize the NPs from the waste streams and the role of potential microorganisms such as microalgae, fungi, yeast, bacteria for the synthesis of NPs have been discussed. A critical insight is also given on use of recycling technologies and the incorporation of NMs in the membrane bioreactors (MBRs) to improve membrane functioning and process performance. Finally, this study aims to mitigate various persisting scientific and technological challenges for the safe disposal and recycling of organic and inorganic waste for future use in the circular economy.

Abstract
Though many studies pertaining to soil bioremediation have been performed to study the microbial kinetics in shake flasks, the process efficiency in column tests is seldom. In the present study, soil columns tests were carried out to study the biodegradation of soil contaminated with a high concentration of diesel (≈19.5 g/kg) petroleum hydrocarbons expressed as C10-C50. Experiments were done with crude enzymatic cocktail produced by the hydrocarbonoclastic bacterium, Alcanivorax borkumensis. A. borkumensis was grown on a media with 3% (v/v) motor oil as the sole carbon and energy source. The effects of the enzyme concentration, treatment time and oxidant on the bioremediation efficiency of C10-C50 were investigated. A batch test was also carried out in parallel to investigate the stability of the enzymes and the effect of the biosurfactants on the desorption and the bioconversion of C10-C50. Batch tests indicated that the biosurfactants significantly affected the desorption and alkane hydroxylase and lipase enzymes, maintained their catalytic activity during the 20-day test, with a half-life of 7.44 days and 8.84 days, respectively. The crude enzyme cocktail, with 40 U/mL of lipase and 10 U/mL of alkane hydroxylase, showed the highest conversion of 57.36% after 12 weeks of treatment with a degradation rate of 0.0218 day-1. The results show that the soil column tests can be used to optimize operating conditions for hydrocarbon degradation and to assess the performance of the overall bioremediation process.

Production of hydrocarbon-degrading microorganisms using agricultural residues of Mangifera indica L. and Carica papaya as carbon source. 3 Biotech 2019; 9:43. [PMID: 30675453 DOI: 10.1007/s13205-019-1574-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2018] [Accepted: 01/11/2019] [Indexed: 11/26/2022] Open
Abstract
The aim of the present study was to evaluate the potential of oils from agricultural residues, such as Mangifera indica L. (mango) and Carica papaya (papaya) from the Papaloapan region, Mexico, as a carbon source for the production of hydrocarbon-degrading (hydrocarbonoclastic) microorganisms in an airlift bioreactor via a common metabolic pathway for hydrocarbons and fatty acids. Biomass growth and carbon source uptake were measured using optical density and gas chromatography, respectively. Gompertz, logistic, and Von Bertalanffy mathematical models were used to obtain kinetic parameters such as the lag phase, maximum specific growth, and consumption rate. The hydrocarbonoclastic consortium was able to grow using papaya (6.09 ± 0.23 g L-1) and mango (2.59 ± 0.30 g L-1) oils, which contain certain antibacterial fatty acids. Differences observed in maximum specific growth and consumption rates indicate that, although mango oil was consumed faster (0.33 day-1 for mango and 0.25 day-1 for papaya), papaya oil provided a higher rate of biomass production per microorganism (0.24 day-1 for mango and 0.44 day-1 for papaya). Additionally, the consortium was able to consume 13 g L-1 diesel as a sole carbon source and improve its maximum specific consumption rate following growth using the oils. Furthermore, the maximum specific growth rate was decreased, indicating a change in the consortium capabilities. Nevertheless, agricultural waste oils from the Papaloapan region can be used to cultivate hydrocarbonoclastic microorganisms. The present study creates the possibility of investigating carbon sources other than hydrocarbons for the production of hydrocarbonoclastic microorganisms.
