Three hydrocarbonoclastic bacteria isolated from crude oil-impacted mesotidal waters of the Niger Delta area of Nigeria, and identified, by 16S rRNA sequencing, as Vibrio fluvialis OWPB63, Serratia sp. MWPB18 and Pseudomonas fluorescens OWPB17 demonstrated commendable protease production ability in skimmed milk-minimal medium. Protease biosynthesis commenced in all three bacteria before the first 2 h of fermentation with peak productivities of 4.12, 0.73 and 1.12 μg/mL/h reached at 12, 36 and… Expand

Kinetic modeling and quasi-economic analysis of fermentative glycolipopeptide biosurfactant production in a medium co-optimized by statistical and neural network approaches
Results showed that bio-catalytic rates of lipase and urease reached exponential values within the first 12 h of fermentation leading to high specific rates of substrate consumption and bacterial growth, suggesting that glycolipopeptide biosynthesis may proceed through stationary phase transpeptidation of the Glycolipid base.

Comparative Toxicity of Water Soluble Fractions of Four Oils on the Growth of a Microalga
Experimental data has shown that different oils have different potential for environmental damage, depending on the types and concentration of soluble and dispersed hydrocarbon present in the WSF. Expand
Deleterious effects of water-soluble fraction of petroleum, diesel and gasoline on marine pejerrey Odontesthes argentinensis larvae.
The histological examination of pejerrey larvae exposed to WSF of petroleum, diesel and gasoline after 96 h revealed a variety of lesions in the larvae, which are of importance since much attention has been paid to large visible surfaces of petroleum spills instead of potential toxic effects of dissolved aromatic hydrocarbons, which is more available to marine biota.

Low-cost fermentative medium for biosurfactant production by probiotic bacteria
Results obtained showed that supplemented cheese whey and molasses media can be used as a relatively inexpensive and economical alternative to synthetic media for biosurfactant production by probiotic bacteria, thus an attractive alternative as many of the potential applications for biosURfactants depend on whether they can be produced economically.
