Arsenic availability, toxicity and direct role of GSH and phytochelatins in As detoxification in the green alga Stichococcus bacillaris.
TLDR
The intracellular concentration of As was greater than that of non-protein SH groups which suggests that not all the arsenic in algal cells was complexed and detoxified by thiol groups.
Concentrations of phytochelatins and glutathione found in natural assemblages of seaweeds depend on species and metal concentrations of the habitat.
TLDR
Results clearly show that natural assemblages of seaweeds, belonging to disparate phylogenetic groups produce PCs when exposed to a mixture of metals in their environment, however, the involvement of thiol peptides in metal homeostasis, detoxification and resistance varies between seaweed species that are growing under the same environmental conditions.
Phytochelatin production in freshwater algae Stigeoclonium in response to heavy metals contained in mining water; effects of some environmental factors.
TLDR
Production of phytochelatins (PC) in algae of the genus Stigeoclonium exposed to the heavy metal mixture is discussed in the context of various metal bioavailability and the algal adaptation to complex aquatic environment.
Relationship between Cyanobacterial bloom composition and anatoxin-a and microcystin occurrence in the eutrophic dam reservoir (SE Poland)
TLDR
First time in Poland, mass occurrence of Anabaena strains producing anatoxin-a was observed and the total abundance of potential microcystin producers was positively correlated with the content of these hepatotoxins in the reservoir water.
Resistance, accumulation and allocation of zinc in two ecotypes of the green alga Stigeoclonium tenue Kütz. coming from habitats of different heavy metal concentrations
TLDR
The data obtained suggest that the Zn-tolerant ecotype S. tenue (T) is able to detoxify the excess of accumulated zinc more effectively than the sensitive ecotype, however, vacuolar Zn compartmentalisation does not seem be the main tolerance mechanism.
Influence of photoperiods on the growth rate and biomass productivity of green microalgae
TLDR
The unicellular species of the green microalgae from the genus Neochloris, examined for the first time in this study, are promising prospective objects for algal biotechnology.
Correlations between toxic Pb effects and production of Pb-induced thiol peptides in the microalga Stichococcus bacillaris.
TLDR
It has been stated, on the basis of the level of Pb-induced thiol peptides, that Pb availability to algae changed significantly within the range of the pH values studied, and was limited in the presence of calcium and of some complexing ligands like orthophosphate, chloride and citrate.
Response of two terrestrial green microalgae (Chlorophyta, Trebouxiophyceae) isolated from Cu-rich and unpolluted soils to copper stress.
TLDR
Low intracellular Cu-accumulation and maintenance of high GSH level concomitant with PCs production seem to be responsible for a higher Cu-resistance of S. minor than G. terricola.
Effects of microcystin-containing cyanobacterial extract on hematological and biochemical parameters of common carp (Cyprinus carpio L.)
TLDR
It is concluded that not only consumption of food containing toxins but also MCs dissolved in water may pose a threat to fish health and detected changes in lysozyme and ceruloplasmin activity may have distinct effects in fish resistance against pathogens or oxidative stress.
Toxicity of cyanobacterial bloom in the eutrophic dam reservoir (Southeast Poland).
TLDR
High-performance liquid chromatography analysis of surface scum sampled during Anabaena circinalis domination revealed the presence of anatoxin-a at a high concentration, and the cyanobacterial extract was classified at class IV toxicity, which means high toxic hazard.
