Recent developments in microbial oils production: a possible alternative to vegetable oils for biodiesel without competition with human food? BABT
Christophe,Gwendoline; Kumar,Vinod; Nouaille,Régis; Gaudet,Geneviève; Fontanille,Pierre; Pandey,Ashok; Soccol,Carlos Ricardo; Larroche,Christian.
Since centuries vegetable oils are consumed as human food but it also finds applications in biodiesel production which is attracting more attention. But due to being in competition with food it could not be sustainable and leads the need to search for alternative. Nowdays microbes-derived oils (single cell oils) seem to be alternatives for biodiesel production due to their similar composition to that of vegetable oils. However, the cold flow properties of the biodiesel produced from microbial oils are unacceptable and have to be modified by an efficient transesterification. Glycerol which is by product of transesterification can be valorised into some more useful products so that it can also be utilised along with biodiesel to simplify the downstream...

Biodiversity of the oleaginous microorganisms in Tibetan Plateau BJM
Li,Shi Lin; Lin,Qiang; Li,Xin Ran; Xu,Hui; Yang,Yun Xi; Qiao,Dai Rong; Cao,Yi.
Microbial lipids, which are also known as single cell oils (SCO), are produced by oleaginous microorganisms including oleaginous bacteria, yeast, fungus and algae through converting carbohydrates into lipids under certain conditions. Due to its unique environment having extremely low temperature and anoxia, the Tibetan Plateau is amongst the regions with numerous rare ecotypes such as arid desert, salt marsh, alpine permafrost, hot spring, and lawn. By using a rapid, convenient screening method, we identified 31 strains of oleaginous microorganisms from different habitats in the Tibetan Plateau, which include wetlands, lawn, hot spring, alpine permafrost, and saline-alkali soil. Molecular identity analysis showed that they belong to 15 different species, 7...
