Genetic polymorphism in brazilian microcystis spp. (Cyanobacteria) toxic and non-toxic through RFLP-PCR of the cpcBA-IGS [PDF]

, 2009
The escalating occurrence of cyanobacterial toxic blooms demands a better understanding of genetic variability as an auxiliary expedient in species identification, collaborating with the monitoring of water destined to public supply.

The molecular ecology of Microcystis sp. blooms in the San Francisco Estuary

Environmental Microbiology, 2017
Summary Harmful blooms of the cyanobacterium Microcystis sp. have become increasingly pervasive in the San Francisco Estuary Delta (USA) since the early 2000s and their rise has coincided with substantial decreases in several important fish species.

“Chlorella” sp. as a food supplement during the Nile tilapia larviculture "Chlorella" sp. como suplemento alimentar durante a larvicultura de tilápia do Nilo

Revista Brasileira de Saúde e Produção Animal, 2011
This study aimed to evaluate the Chlorella sp. influence as a food supplement on Nile tilapia, Oreochromis niloticus, larviculture. The experimental design was completely randomized and consisted of three treatments and three replicates. In one treatment

Cianobactérias e Toxicidade: Impacte na Saúde Pública em Portugal e no Brasil [PDF]

, 2012
Um aumento da concentração de nutrientes na água poderá desencadear fluorescências de cianobactérias (densidades >200 cel/mL). Sob determinadas condições as cianobactérias produzem toxinas responsáveis pelo envenenamento de animais e humanos.

The toxic effects of meta‐tyrosine are related to its misincorporation into the proteome and to altered metabolism in cyanobacteria

The FEBS Journal, Volume 292, Issue 20, Page 5439-5456, October 2025.
This study reveals that meta‐tyrosine (m‐Tyr), a nonproteinogenic analog of aromatic amino acids, disrupts protein synthesis and photosynthesis in cyanobacteria by being misincorporated by Phenylalanyl‐tRNA synthetase (PheRS) into essential proteins. Through molecular, biochemical, and proteomic analyses in Synechocystis, the research shows that m‐Tyr ...

Bacteria homologus to Aeromonas capable of microcystin degradation [PDF]

, 2014
Water blooms dominated by cyanobacteria are capable of producing hepatotoxins known as microcystins. These toxins are dangerous to people and to the environment. Therefore, for a better understanding of the biological termination of this increasingly

Demographic responses of Heterocypris incongruens (Ostracoda) related to stress factors of competition, predation and food

Journal of Limnology, 2016
Heterocypris incongruens is a widely distributed ostracod which can maintain its populations under stressful conditions such as those in temporary ponds and under low-quality diets, for example, detritus.

Potentially Toxic Cyanobacteria and Quantification of Microcystin-LR and Cylindrospermopsine in Four Dams of Guanajuato, Mexico

Nova Scientia
The quality and availability of water are at risk due to the presence of cyanobacteria blooms capable of producing cyanotoxins. The purpose of this research was to determine their occurrence in four dams in Mexico.

Grazing on Microcystis (Cyanophyceae) by testate amoebae with special reference to cyanobacterial abundance and physiological state [PDF]

, 2011
We examined the growth of testate amoebae preying on Microcystis whose physiological states were different in laboratory experiments and a hypertrophic pond.
