Superior 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 کاملSuperior triacylglycerol (TAG) accumulation in starchless mutants of Scenedesmus obliquus: (II) evaluation of TAG yield and productivity in controlled photobioreactors
BACKGROUND Many microalgae accumulate carbohydrates simultaneously with triacylglycerol (TAG) upon nitrogen starvation, and these products compete for photosynthetic products and metabolites from the central carbon metabolism. As shown for starchless mutants of the non-oleaginous model alga Chlamydomonas reinhardtii, reduced carbohydrate synthesis can enhance TAG production. However, these muta...
متن کاملPhotolability of Photosynthesis in Two Separate Mutants of Scenedesmus obliquus: Preferential Inactivation of Photosystem I.
Two separate mutants of the green alga, Scenedesmus obliquus, are described in which photosynthesis is sensitive to moderate intensities of white light (100 mw cm(-2)). Heterotrophic cultures of both mutants lose photosynthetic activity when exposed to white light; the site of at least the initial phase of this inactivation is within photosystem I. Although all whole cell and cell-free reaction...

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...
