Screening acute cytotoxicity biomarkers using a microalga as test organism.
The present study checked the suitability of the integration of flow cytometry (FCM) as technique and a freshwater microalga (Chlamydomonas moewusii) as cell system model for ecotoxicological studies, looking for sensitive biomarkers of acute cytotoxicity of potential contaminants in aquatic systems. The detection of the potential acute toxicity of a pollutant is of interest because pulse disch...
متن کاملComparison of the sensitivity of different toxicity test endpoints in a microalga exposed to the herbicide paraquat.
The use of herbicides constitutes the principal method of weed control but the introduction of these compounds into the aquatic environment can provoke severe consequences for non-target organisms such as microalgae. Toxic effects of these pollutants on microalgae are generally evaluated using phytotoxicity tests based on growth inhibition, a population-based parameter. However, physiological c...
متن کاملBiosynthesis of Silver Nanoparticles Using Chlamydomonas reinhardtii and its Inhibitory Effect on Growth and Virulence of Listeria monocytogenes
Background: Biosynthesis of nanoparticles using microorganisms, enzymes, and plant extracts is regarded as an alternative to chemical methods. Microalgae appear to be an efficient biological platform for nanoparticle synthesis as they grow rapidly and produce large biomass at lower cost. Objectives: The possibility of silver nanoparticles biosynthesisby freshwater green microalgae, Chlamydomona...
متن کاملInvestigation of an Optimized Context for the Expression of GFP as a Reporter Gene in Chlamydomonas Reinhardtii
Background: Chlamydomonas reinhardtii is a novel recombinant eukaryotic expression system with many advantages including fast growth rate, rapid scalability, absence of human pathogens and the ability to fold and assemble complex proteins accurately, however, obstacle relatively low expression level necessitates optimizing foreign gene expression in this system. The Green Fluorescent Protein (G...
متن کاملThe herbicide paraquat induces alterations in the elemental and biochemical composition of non-target microalgal species.
Huge quantities of pesticides are dispersed in the environment, affecting non-target organisms. Since paraquat affects the photosynthetic process, the biochemical composition of affected species should be altered. The effect of paraquat on Chlamydomonas moewusii, a freshwater non-target species, was studied. After 48 h of herbicide exposure, growth rate, dry weight, and chlorophyll a and protei...
