Transfer ribonucleic acid from Scenedesmus obliquus D3.
Scenedesmus obliquus is a green alga whose cells have a well-defined nucleus, and contain a chloroplast. Even when grown in the dark these cells retain their chloroplast. Because of the toughness of the cell wall, extraction of tRNA requires either vigorous homogenization of the cells before phenol extraction or prolonged phenol extraction at 60°C. Determination of the amount of tRNA and its pu...
متن کاملSuperior triacylglycerol (TAG) accumulation in starchless mutants of Scenedesmus obliquus: (I) mutant generation and characterization
BACKGROUND Microalgae are a promising platform for producing neutral lipids, to be used in the application for biofuels or commodities in the feed and food industry. A very promising candidate is the oleaginous green microalga Scenedesmus obliquus, because it accumulates up to 45% w/w triacylglycerol (TAG) under nitrogen starvation. Under these conditions, starch is accumulated as well. Starch ...
متن کاملRising Water Temperatures Alter Lipid Dynamics and Reduce N-3 Essential Fatty Acid Concentrations in Scenedesmus Obliquus (chlorophyta)(1).
The biosynthesis of nutritionally important polyunsaturated fatty acids (PUFAs) in phytoplankton is influenced by environmental temperature. We investigated the potential of climate warming to alter lipid dynamics of Scenedesmus obliquus (Turpin) Kütz. by comparing lipid and fatty acid (FA) profiles as well as FA metabolism (using [1-(14) C] acetate) at 20°C and 28°C. We documented an overall d...
متن کاملAccumulation of Cu by Microalgae Scenedesmus obliquus and Synechocystis sp. PCC 6803
This study focused on the use of microbial potential for metal ion removal. Scenedesmus obliquus and Synechocystis sp. PCC 6803 were compared for accumulation of Cu in batch mode. During time course accumulation, S. obliquus accumulated Cu up to 124 μg mg -1 dry wt after 1h of incubation, whereas for Synechocystis sp. PCC 6803 it reached up to 64.9 μg mg -1 dry wt after 2h. Low biomass concentr...
متن کاملFormation of Large Thioredoxin / Accompanies Chloroplast Development in Scenedesmus obliquus
Chloroplast-free mutant cells C-2A ' of the green algae Scenedesmus obliquus lack thioredoxin / , which functions in the light activation of chloroplast enzymes, but do con tain the regular thioredoxins I and II. When dark-grown algae are transferred to light, thioredoxin / activity appears rapidly and increases in parallel with photosynthetic ac tivities; however it precedes chlorophyll bios...
