Vernalophrys algivore gen. nov., sp. nov. (Rhizaria: Cercozoa: Vampyrellida), a New Algal Predator Isolated from Outdoor Mass Culture of Scenedesmus dimorphus.
Microbial contamination is the main cause of loss of biomass yield in microalgal cultures, especially under outdoor environmental conditions. Little is known about the identities of microbial contaminants in outdoor mass algal cultures. In this study, a new genus and species of vampyrellid amoeba, Vernalophrys algivore, is described from cultures of Scenedesmus dimorphus in open raceway ponds a...
متن کاملThe growth of Scenedesmus sp. attachment on different materials surface
BACKGROUND Microalgae has been concerned as a potential source of biodiesel in the recent years. However, it is costly to harvest microalgae as it is commonly cultured in water and the cells are too small to harvest. In order to reduce the cost of cultivation and harvesting, it is important to improve the biomass productivity of microalgae. Here, we utilized the attachment method to culture mic...
متن کاملThe Growth of Monoraphidium sp. and Scenedesmus sp. Cells in the Presence of Thorium
Toxicity of thorium by Monoraphidium sp. and Scenedesmus sp. was studied. Microalgal cultures were inoculated in ASM-1 medium in presence and absence of thorium. Its effect was monitored by direct counting on Fuchs-Rosenthal chamber and with software. The toxicity of thorium over the species was observed for concentrations over 50.0 mg/L. After 30 days, Monoraphidium cells decreased their conce...
متن کاملCultivation of Microalgae Chlorella sp. and Scenedesmus sp. as a Potentional Biofuel Feedstock
The growth of two robust algae strains Chlorella sp. and Scenedesmus sp. growing in Lithuanian lakes was investigated with the aim to obtain optimum conditions for biomass cultivation for biofuel production in the Lithuanian environment. Samples were taken from different nitrogen sources and of different concentrations, with addition of various concentrations of CO2 and in the presence of salt....
متن کاملThe effect of immobilization of Scenedesmus sp. ISC 109 on potential of reduction of Chromium
Recently, biological methods are used for remediation of various pollutants especially heavy metals. Algae are organisms which can accumulate and transform these pollutants with different mechanisms. In this regard immobilization of these microorganisms is a technique that is used for different purpose. So after primary screening of microalgae (Spirulina, Tetraselmis, Chlorella, Scenedesmus, Mi...
