Under anaerobic conditions, microcystins (MCs)-degrading bacteria from shrimp pond sediment and the intestine were repeatedly enriched using Widdel medium with MCs as sole source of carbon nitrogen. The succession two bacterial communities during enrichment was compared, MC-degrading strains isolated final communities. results showed that, increase in time, alpha diversity indices decreased significantly at first (p<0.05) then increased gradually, but difference not significant...
To investigate the effects of lead(II) on production extracellular polysaccharides (EPS), including bound (bEPS) and soluble (sEPS), colony formation Microcystis aeruginosa, cultures M. aeruginosa were exposed to four concentrations (5.0, 10.0, 20.0 40.0 mg/L) for 10 d under controlled laboratory conditions. The results showed that 5.0 10.0 mg/L stimulated growth throughout experiment while inhibited in first 2 exposure then it. As compared control group, significant increases bEPS sEPS...
With the increasing occurrence of dietary lead (Pb) contamination in aquaculture, a better understanding toxic effects Pb on aquatic animals is needed. Tilapia (Oreochromis niloticus) were exposed to at concentrations 0, 100, 400 and 800 μg g−1 dry weight for 60 days, accumulation tissues blood, oxidative stress posterior kidney DNA damage peripheral blood cells investigated. The results showed that exposure resulted significant which increased with concentrations. accumulated sampled...
The effects of 40 Chinese herbs on Microcystis aeruginosa growth were monitored spectrophotometrically. Golden thread (Coptis chinensis) exhibited the best inhibitory effects. Cell density M. decreased with increasing concentrations golden and prolongation exposure time. Decreases in protein content, carbohydrate chlorophyll a content observed concentration-dependent manner after 96 h exposure. Changes cell density, exposed to berberine, main component thread, also investigated. It was that...
Abstract Berberine is a potent algicidal allelochemical of Microcystis aeruginosa. To optimize its application in the control blooms, effects berberine on growth and photosynthetic activities M. aeruginosa non-target green alga, Chlorella pyrenoidosa, were compared. The results showed that activity was light dependent. had no C. pyrenoidosa with or without exposure. Under light-dark conditions, significantly decreased chlorophyll fluorescence parameters while significant berberine-induced...
To investigate the sequestration and distribution characteristics of Cd(II) by Microcystis aeruginosa its role in colony formation, M. was exposed to six different concentrations for 10 days. exposure caused hormesis growth .

The cyanobacterium Microcystis occurs as colonies of different sizes with varying abundance toxic genotypes versus non-toxic under natural conditions. To investigate the effects on colony formation, samples collected from mainstream Haihe River July to October 2015 were sieved into four classes <8 μm, 8-20 20-90 μm and >90 μm. Each size class was analyzed for proportion genotypes, microcystins (MCs) cellular production genotypes. results showed smallest (<8 μm) lowest highest MC-RR MC-YR...
To understand how environmental conditions affect the allelopathic inhibition of toxic Microcystis aeruginosa by berberine, independent effects some factors, including temperature, light, and aeration, on growth extracellular microcystin (MC) content M. (FACHB 905) treated with 0.000 0.001% (w/v) berberine were investigated. The results showed that higher temperature light density, aeration in daytime beneficial for under measured conditions. closely associated Berberine had best inhibitory...
To further understand the role of attached bacteria in formation Microcystis colonies, we conducted a field investigation Chentaizi River Tianjin, China, which frequently suffers blooms summer. The results showed average cell density was 2.31 × 107 cell/L from July 19 to 27, 2021. Free-living and communities shared similar phylum diversity, but abundance changed obviously. colony size bacterial number an increasing trend during whole sampling period. There significant positive correlation...
