Aerobic Denitrification Promoting by Actinomycetes Coculture: Investigating Performance, Carbon Source Metabolic Characteristic, and Raw Water Restoration

Environmental Science & Technology, Год журнала: 2023, Номер 58(1), С. 683 - 694

The coculture theory that promotes denitrification relies on effectively utilizing the resources of low-efficiency microbes. Here, strains Streptomyces sp. PYX97 and TSJ96 were isolated showed lower capacity when cultured individually. However, enhanced nitrogen removal (removed 96.40% total nitrogen) organic carbon reduction 92.13% dissolved carbon) under aerobic conditions. Nitrogen balance analysis indicated coculturing efficiency nitrate converted into gaseous reaching 70.42%. Meanwhile, promoted cell metabolism source metabolic activity. thrived in conditions C/N = 10, alkalescence, 150 rpm shaking speed. reduced CODMn raw water treatment by 83.32 84.21%, respectively. During this treatment, activity density increased reactor. Moreover, could utilize aromatic protein soluble microbial products during processes treatment. This study suggests inefficient actinomycete be a promising approach for treating polluted bodies.

Increasing fish production in recirculating aquaculture system by integrating a biofloc-worm reactor for protein recovery

Water Research X, Год журнала: 2024, Номер 24, С. 100246 - 100246

Aquaculture, producing half of global fish production, offers a high-quality protein source for humans. Improving nitrogen use efficiency (NUE) through microbial recovery is crucial increasing production and reducing environmental footprint. However, the poor palatability high moisture content make its utilization challenging. Here, biofloc-worm reactor was integrated into recirculating aquaculture system (BW_RAS) first time to convert Tubificidae (Oligochaeta) biomass, which used as direct feed culturing fish. Batch experiments indicated that an aeration rate 0.132 m
