A deep-sea isolate of the psychrotolerant yeast Cryptococcus sp. (NIOCC#PY13) obtained from polymetallic nodule-bearing sediments of the Central Indian Basin was examined for its capacity to grow in the presence of various concentrations of the heavy metal salts i.e., ZnSO4 , CuSO4 , Pb(CH3 COO)2 and CdCl2 . It demonstrated considerable growth in the presence of 100 mg/l concentrations of the a...
BACKGROUND Microbial lipids are produced by many oleaginous organisms including the well-characterized yeast Yarrowia lipolytica, which can be engineered for increased lipid yield by up-regulation of the lipid biosynthetic pathway and down-regulation or deletion of competing pathways. RESULTS We describe a strain engineering strategy centered on diacylglycerol acyltransferase (DGA) gene overe...
The basidiomycetous yeast Rhodosporidium toruloides (anamorph, Rhodotorula glutinis) is a common phylloplane epiphyte with biocontrol potential. To understand how R. toruloides adheres to plant surfaces, we obtained nonadherent fungal mutants after chemical mutagenesis with methane-sulfonic acid ethyl ester. Sixteen attachment-minus (Att-) mutants were identified by three methods: (i) screening...
The augmentation of industrial and house wastes and the accidental oil spills raised the problem of their storage and treatment. Bioremediation is an interesting alternative for restauring the ecological equilibrum in polluted environments, based on microbial population dynamics and its ability to consume xenobiotics as carbon source. The yeast species described as having biodegrading abilities...
Rhodotorula (Rhodosporidium) toruloides is an oleaginous yeast with great biotechnological potential, capable of accumulating lipid up to 70% of its dry biomass, and of carotenoid biosynthesis. However, few molecular genetic tools are available for manipulation of this basidiomycete yeast and its high genomic GC content can make routine cloning difficult. We have developed plasmid vectors for t...
