High substrate costs decrease the profitability of polyhydroxyalkanoates (PHAs) production, and thus low-cost carbon substrates coming from agricultural and industrial residuals are tested for the production of these biopolymers. Among them crude glycerol, formed as a byproduct during biodiesel production, seems to be the most promising source of carbon. The object of this study was to characte...

Prodigiosin is a red pigment produced by Serratia marcescens. Prodigiosin is regarded as a promising drug owing to its reported characteristics of possessing anti-microbial, anti-cancer, and immunosuppressive activity. A factorial design was applied to generate a set of 32 experimental combinations to study the optimal conditions for pigment production using crude glycerol obtained from local b...

Biodiesel is produced by the transesterification of animal fats and vegetable oils, producing a large amount glycerol as by-product. The crude cannot be used in food or pharmaceutical industries. It crucial to transform into value-added products with applications different areas biodiesel economically viable. One possible its use precursor for synthesis carbon materials. glycerol-based material...

Orotic acid is an intermediate of the de novo pyrimidine biosynthesis that plays a crucial role in several nutraceutical supplements. In some microorganisms, blockage this pathway downstream dihydroorotate dehydrogenase (DHOD) leads to orotic accumulation. Here, Ashbya gossypii Agura3 auxotroph was shown accumulate and excrete (~1.5 g/L), trait further explored for production from raw substrate...
