New Findings Reported from Federal University Describe Advances in Science and Technology

May 14, 2014



By a News Reporter-Staff News Editor at Biotech Week -- Current study results on Science and Technology have been published. According to news reporting originating from Fortaleza, Brazil, by NewsRx correspondents, research stated, "Glycerol, a co-product of the biodiesel industry, may be a suitable raw material for the production of high added-value compounds by the microorganisms. This study aimed to use the glycerol obtained from the biodiesel production process as the main carbon source for biosurfactant production by Bacillus subtilis ATCC 6633."

Our news editors obtained a quote from the research from Federal University, "Results indicated that the strain lowered the surface tension of the cell-free fermented broth to 31.5 +/- 1.6 mN/m, indicating the production of biosurfactant. The critical micelle concentration (CMC - 33.6 mN/m) obtained was similar to the previously reported for biossurfactants isolated from other Bacillus."

According to the news editors, the research concluded: "The produced biosurfactant was able to emulsify n-hexadecane and soybean oil."
