The effects of influent 5-Deoxystrigol concentrations on integral biogas upgrading and nutrient removal by different algal-fungal-bacterial consortium
The low quality of biogas and the difficulties in treating biogas slurry are important bottlenecks that limit the development of the fermentation industry. The effects of 5-deoxystrigol (5DS) on the growth rate, daily productivity, and photosynthetic performance of different algal-fungal-bacterial consortia were investigated, and the auxiliary activities of endophytic bacteria (S395–2), Ganoderma lucidum (G. lucidum), Bacillus licheniformis (B. licheniformis), and activated sludge in these systems were examined. The consortium Chlorella vulgaris (C. vulgaris) + G. lucidum + S395–2 was found to be the most effective combination for both biogas upgrading and nutrient removal. Removal efficiencies of chemical oxygen demand (COD), total nitrogen (TN), and total phosphorous (TP) were approximately 82.94 ± 7.88 %, 81.36 ± 7.79 %, and 83.27 ± 8.09 %, respectively, and the CO2 removal efficiency was observed to be about 69.89 ± 6.57 % at the optimum 5DS concentration of 10−11 M. On day 7 of the treatment, the CH4 content was elevated from 66.07 ± 4.84 % to 86.24 ± 8.44 %. The effect of 5DS treatments in different algal-fungal-bacterial consortia was positive in terms of growth performance and photosynthetic rate. The present study provides a framework for efficient biogas upgrading and nutrient removal by the three-phase symbionts.
期刊介绍:
Algal Research is an international phycology journal covering all areas of emerging technologies in algae biology, biomass production, cultivation, harvesting, extraction, bioproducts, biorefinery, engineering, and econometrics. Algae is defined to include cyanobacteria, microalgae, and protists and symbionts of interest in biotechnology. The journal publishes original research and reviews for the following scope: algal biology, including but not exclusive to: phylogeny, biodiversity, molecular traits, metabolic regulation, and genetic engineering, algal cultivation, e.g. phototrophic systems, heterotrophic systems, and mixotrophic systems, algal harvesting and extraction systems, biotechnology to convert algal biomass and components into biofuels and bioproducts, e.g., nutraceuticals, pharmaceuticals, animal feed, plastics, etc. algal products and their economic assessment
