Abstract:
... In this work, the performance and mechanism for the boosting effects of fructose as an additional co-metabolite towards the biological treatment of reactive black 5 were systematically investigated. A decolorization efficiency of 98% was obtained in sample FRU200 (with 3 g/L fructose added based on 3 g/L yeast extract), which was 21% higher than that without fructose. Several intermediates with lo ...

Abstract:
... The present work studied to evaluate the effectiveness under the interaction of bacterial consortium and biochar applied to give impetus to bacterial community activities among cow manure composting. High-throughput sequencing technique and six treatments were carried out: T2, T3 and T6 were single apply of bacteria culture (C), 12%wood biochar (12%WB) and 12%wheat straw biochar (12%WSB), respecti ...

Abstract:
... Succession and metabolism functions of bacterial communities were determined in maize straw composting with earthworm casts and zeolite addition by using high-throughput sequencing, Biolog and PICRUSt. Results showed that earthworm casts and zeolite addition increased the temperature, decreased NH₄⁺ contents and affected bacterial community structure. The relative abundances of Firmicutes and Beta ...

Abstract:
... In this paper, the influence of clay amendment on antibiotic resistance genes (ARGs) fate and their relation with bacterial diversity in poultry manure (PM) composting was evaluated. The results confirmed that 4% clay amendment was significantly reduce the relative abundances (RAs) 94% of ARGs, while higher dosage of clay blended treatments (T5 and T6) composts were observed relatively very high p ...

Bacillus (bacteria); Chlorella vulgaris; antioxidants; bacteria; bacterial communities; biomass; culture media; flocculation; harvesting; microalgae; proteins; recycling
Abstract:
... Microalgal cultivation and harvesting are two main factors that restrict the development of microalgae. To help solve these two questions, flocculating bacteria and recycling culture medium were investigated in this study. Proteins in bacterial cells of Bacillus sp. y3 and y6 exhibited direct flocculation activities on Chlorella vulgaris cells. The recycling culture media after harvest of microalg ...
