Lake Dianchi is a shallow and turbid lake, located in Southwest China. Since 1985, Lake Dianchi has experienced severe cyanabacterial blooms (dominated by Microcystis spp.). In extreme cases, the algal cell densities have exceeded three billion cells per liter. To predict and elucidate the population dynamics of Microcystis spp. in Lake Dianchi, a neural network based model was developed. The c...

Indicator organisms and antibiotic resistance were used as a proxy to measure microbial water quality of ballast tanks of ships, and surface waters in a tropical harbor. The survival of marine bacteria in ballast tanks appeared to diminish over longer water retention time, with a reduction of cell viability observed after a week based on heterotrophic plate counts. Pyrosequencing of 16S rRNA ge...

Cyanobacteria are an important source of natural products. In this article, we briefly review the responses of cyanobacteria to different stresses. Abiotic stresses (temperature, salt, heavy metals, metalloid and ultraviolet (UV) influence cell growth and metabolism in cyanobacteria. Salt stress is a major abiotic factor that decrease...

Algal blooms occur in freshwater bodies throughout the world, often leading to fish kills. Cases of these kills along Ural River were reported 2018–2019, involving significant amount sturgeon farming areas. In this study, analysis algal samples from delta up 100 km inland was carried out August December 2019 using imaging flow cytometry (IFC), molecular biological, and microscopic techniques. W...

aphanius ginaonis is exclusive to the geno hot spring, located in the hormozgan province. in this paper some biological aspects of aphanius ginaonis and contents of its digestive tract and its relation with cyanobacteria (blue-green algae) in the geno hot spring was examined. sampling was conducted monthly, samples were fixed in 5% formalin immediately after fishing and transferred to the ichth...
