Effect of initial cell concentration on ethanol production by flocculent Saccharomyces cerevisiae with xylose-fermenting ability.

abstract：:There is a lack of fundamental knowledge about the scale up of biosurfactant production. In order to develop suitable technology of commercialization, carrying out tests in shake flasks and bioreactors was essential. A reactor with integrated foam collector was designed for biosurfactant production using Bacillus subt...
