Subjective interview quality metrics predict scoring performance in the administration of the PANSS

The strain Bacillus oceanisediminis H2, which was isolated from tannery processing industrial wastelands, grown on biosurfactant production media supplemented with glucose as carbon source and urea as nitrogen source was successful in the production of a crude biosurfactant. The crude biosurfactant was purified using silica-gel column chromatography and thin layer chromatography (TLC), which was then lyophilized for further analysis. TLC of both the crude and purified biosurfactant showed similar Rf values of 0.678 (of one of the spots) and 0.614 respectively. The solid purified product was then subjected to FTIR and LC-MS analysis which confirmed that the purified biosurfactant is surfactin by nature. The crude biosurfactant produced has the ability to reduce surface tension to 46.909 mN/m from 72 mN/m as that of water.
