Although single-species laboratory toxicity tests with microalgae are sensitive and highly reproducible, they lack environmental realism. Interactions between algae and their associated bacteria, either in the plankton or in biofilms, may alter algal sensitivity to contaminants, which are not mimicked in laboratory toxicity tests. This study investigated the effects of simple algal-bacterial re...

Abstract
 Nowadays, the use of microalgae species as raw materials in biopharmaceutical production is on agenda. The reason behind this idea that are cell factories able to efficiently utilize carbon dioxide for numerous biologically active compounds. However, there several problems remain be solved recombinant protein from microalgaes. One critical requirements produce a bio-compatible N-...

Microalgae are a natural source of lipids, carotenoids, and other value-added compounds. The combination nutrients their precise ratio have significant impact on the productivity microalgae-mediated biomass, lipid, chlorophyll, carotenoid production three microalgae species, namely, Monoraphidium sp., Chlorella sorokiniana, Scenedesmus obliquus, were investigated by employing standard photoauto...

Microalgae based biofuels are getting attention due to energy crisis and enviromental protection. In the present study, the Chlorella sp. was cultivated in BG-11 medium at batch mode. The effect of different nitrogen (sodium nitrate, potassium nitrate and urea) and organic carbon (glucose, glycerol and sucrose) sources were analyzed on growth and lipid accumulation on this species. The highest ...

<p>An experimental research on production of biodiesel from lipids chlorella vulgaris has been done through transesterification reaction process. The series cultures carried out and the optimum growth time was determined. synthesis is processed by two steps i.e., isolation lipids. objective study to develop a simultaneous waste water treatment system renewable energy utilizing algal growt...

BACKGROUND Lack of accounting for proton uptake and secretion has confounded interpretation of the stoichiometry of photosynthetic growth of algae. This is also problematic for achieving growth of microalgae to high cell concentrations which is necessary to improve productivity and the economic feasibility of commercial-scale chemical production systems. Since microalgae are capable of consumin...

Microalgae biomass has become a valuable material, the attractiveness of which is familiar to a wider group of customers, not only as a biomass (a prepared product), but also as a raw material for the production of a number of valuable substances like ethanol, hydrogen, hormones, biostimulants, and many other. Human nutrition, animal feeding, biofuel production, and sustainable agriculture – th...
