Wongkiew S, Polprasert C, Noophan PL, Koottatep T, Kanokkantapong V, Surendra KC, Khanal SK. Effects of vermicompost leachate on nitrogen, phosphorus, and microbiome in a food waste bioponic system. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2023; 339:117860. [PMID: 37086642 DOI: 10.1016/j.jenvman.2023.117860] [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: 02/22/2023] [Revised: 03/29/2023] [Accepted: 04/01/2023] [Indexed: 05/03/2023]
Abstract
Food waste is rich in nutrients, such as nitrogen and phosphorus, and can be integrated with bioponics, a closed-loop agricultural system that combines hydroponics with biological nutrient recovery. Vermicompost leachate (VCL) supplementation has been shown to improve the co-composting of organic waste (i.e., compost quality) and the biodegradation of organic compounds. Thus, VCL has high potential for enhancing nutrient availability in bioponics from food waste. However, the understanding of nitrogen and phosphorus availability in food waste-based bioponics is limited, both with and without VCL. In this study, food waste derived from cafeteria vegetable waste was used as the substrate (500 g dry wt./system) in bioponics to grow lettuce (Lactuca sativa L.) for two consecutive cycles (35 days/cycle) without substrate replacement. VCL was applied weekly (1-5% v/v) and compared to the control without VCL. The results showed that the food waste in bioponics provided nitrogen and phosphorus for plant growth (15.5-65.8 g/lettuce head). Organic-degrading and nutrient-transforming bacteria (Hydrogenispora, Clostridium_sensu_stricto_1, Ruminiclostridium_1, Cellvibrio, Thauera, Hydrogenophaga, and Bacillus) were predominantly found in plant roots and residual food waste. VCL addition significantly increased nitrate, phosphate, and chemical oxygen demand levels in bioponics, owing to the nutrients in VCL and the enhancement of keystone microorganisms responsible for organic degradation and nutrient cycling (e.g., Ellin6067, Actinomyces, and Pirellula). These findings suggest that nitrogen, phosphorus, and organic carbon concentrations in an ecosystem of nutrient-transforming and organic-degrading microbes are key in managing nutrient recovery from food waste in bioponics.

Abstract
Despite the important roles that marine sponges play in ecosystem functioning and structuring, little is known about how the sponge holobiont responds to local anthropogenic impacts. Here we assess the influence of an impacted environment (Praia Preta) on the microbial community associated with the endemic sponge Aplysina caissara in comparison to a less-impacted area (Praia do Guaecá) from the coast of São Paulo state (Brazil, southwestern Atlantic coast). We hypothesized that the local anthropogenic impacts will change the microbiome of A. caissara and that the community assembly will be driven by a different process (i.e. deterministic versus stochastic) under distinct levels of impact. The microbiome at the amplicon sequence variants level was found to be statistically distinct between sponges from the different sites, and this was also seen for the microbial communities of the surrounding seawater and sediments. Microbial communities of A. caissara from both sites were found to be assembled by deterministic processes, even though the sites presented distinct anthropogenic impacts, showing a pivotal role of the sponge host in selecting its own microbiome. Overall, this study revealed that local anthropogenic impacts altered the microbiome of A. caissara; however, assembly processes are largely determined by the sponge host.

Abstract
Identification of dissimilatory nitrate reduction to ammonium (DNRA) and denitrification in the dynamic cake layer of a full-scale anoixc dynamic membrane bioreactor (AnDMBR) for treating hotel laundry wastewater was studied. A series of experiments were conducted to understand the contributions of DNRA and canonical denitrification activities in the dynamic cake layer of the AnDMBR. The dynamic cake layer developed included two phases - a steady transmembrane pressure (TMP) increase at 0.24 kPa/day followed by a sharp TMP jump at 1.26 kPa/day four to five days after the AnDMBR start-up. The nitrogen mass balance results showed that canonical denitrification was predominant during the development of the dynamic cake layer. However, DNRA activity and accumulation of bacteria equipped with a complete DNRA pathway showed a positive correlation to the development of the dynamic cake layer. Our metagenomic analysis identified an approximately 18% of the dynamic cake layer bacterial community has a complete DNRA pathway. Pannonibacter (1%), Thauera (0.8%) and Pseudomonas (3%) contained all genes encoding for funcional enzymes of both DNRA (nitrate reductase and DNRA nitrite reductase) and denitrification (nitrate reductase, nitrous oxide reductase and nitric oxide reductase). No other metagenome-assembled genomes (MAGs) possessed a complete cononical denitrification pathway, indicating food-chain-like interactions of denitrifiers in the dynamic cake layer. We found that COD loading rate could be used to control DNRA and canonical denitrification activities during the dynamic cake layer formation.

Abstract
As the most widely used anionic surfactant, linear alkylbenzene sulfonate (LAS) requires biological alkane degradation when it is treated using an activated sludge (AS) process in a wastewater treatment plant because of its structural carboxylic unavailability. As consumption of LAS is gradually increasing, LAS loading into the WWTP is accordingly increasing. However, fewer studies have examined the involvement of the AS microbial community in the LAS degradation. In this study, metagenomic approaches were used to define microbiomes involved in LAS degradation in AS, with a particular focus on ω-hydroxylation. The abundance and diversity of alkane-degrading genes were investigated, and these genes were integrated with reconstructed metagenome-assembled genomes (MAGs). Additionally, the association of functional genes and MAGs with respect to LAS degradation was investigated. The results showed that alkB and cytochrome P450 genes were only shared within specific MAGs. Unique sets of genes with diverse abundances were detected in each sample. The MAGs with the alkB and cytochrome P450 genes were strongly associated with the other MAGs and involved in positive commensal interactions. The findings provided significant insights into how the AS microbiomes, which have continuously treated anionic surfactants for decades, potentially metabolize LAS and interact with commensal bacteria.

Deterioration of biological pollutants removal induced by linear alkylbenzene sulphonates in sequencing batch reactors: Insight of sludge characteristics, microbial community and metabolic activity. BIORESOURCE TECHNOLOGY 2020; 315:123843. [PMID: 32688258 DOI: 10.1016/j.biortech.2020.123843] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/13/2020] [Revised: 07/07/2020] [Accepted: 07/10/2020] [Indexed: 06/11/2023]
Abstract
Linear alkylbenzene sulfonates (LAS) are widely detected in wastewater, and pose potential risks to environment. The influences of LAS on the typical pollutants removal in sequencing batch reactors (SBRs) were evaluated. The results indicated that the removal efficiency of COD, NH4+ and PO43- was respectively reduced by 10.5-27.5%, 5.4-7.3% and11.6-28.9% with the exposure of 10-50 mg/L LAS. Mechanisms investigation found that LAS disrupted the sludge structure and reduced the biomass in reactors due to the saponification effects. Also, the presence of LAS altered the microbial community of activated sludge, and reduced the abundances of functional bacterial responsible for pollutants removal (i.e.Candidatus Accumulibacter, Nitrospira, Denitratisoma and etc.). Moreover, the LAS exhibited negative impacts on the microbial activity with increased LDH release but decreased ATP concentration. The genes expressions for microbial metabolism (i.e. carbohydrate metabolisms, energy metabolism) and typical pollutants removal (i.e. electron transport, phosphonate transport) were all downregulated in LAS-exposed SBRs.

Abstract
This review summarizes the recent development and studies of anaerobic membrane bioreactor (AnMBR) to control fouling issues. AnMBR is an emerging waste water treatment technology mainly because of its low sludge residual, high volumetric organic removal rate, complete liquid-solid separation, better effluent quality, efficient resource recovery and the small footprint. This paper surveys the fundamental aspects of AnMBRs, including its applications, membrane configurations, and recent progress for enhanced reactor performance. Furthermore, the membrane fouling, a major restriction in the practical application of AnMBR, its mechanism and antifouling strategies like membrane cleaning, quorum quenching, ultrasonic treatment, membrane modifications, and antifouling agents are briefly discussed. Based on the review, the key issues that require urgent attention to facilitate large scale and integrated application of AnMBR technology are identified and future research perspectives relating to the prevalent issues are proposed.
