Candida lipolytica is shown to produce an extracellular polymer with emulsifying properties when grown on n-tetradecane or a mixture of linear hydrocarbons. A device for biosurfactant isolation is presented. The polymers recovered from the fermentation broth were found to be complex molecules with a

โฆ Synopsis
Induction of ascospore formation in hydrocarbon utilizing aseosporogenous yeasts was observed during the growth of the yeasts on gas oil, diesel oil, white kerosene and n-alkanes. Studies of relationships between cell morphology and cell growth showed that ascospores were formed during the active growth phase on gas oil but not on glucose. Contact of yeast cells with hydrocarbons may be the possible reason for sporogenesis on hydrocarbons.

The transport of insoluble siibstrates such as hydrocarbons to microorganisms is often postulated to be dictated by the availability of the hydrocarbon surface area. Many publications, qualitative and quantitative, have appeared to substantiate this hypothesis. Experiments have been performed in our
