The production of extracellular polysaccharides by a hydrocarbon assimilating yeast.
Investigations were made on the extracellular polysaccharides production by a hydrocarbon assimilating yeast. The yeast Candida lipolytica was grown on two different media containing n-hexadecane as the sole carbon source. Polymeric materials precipitated from the culture medium with ethanol were determined gravimetrically at various growth periods. The hydrolysis of the precipitated material and their chromatographic analysis revealed the presence of mannose, glucose and galactose in the yeast extract-containing medium. The proportions of these sugars differed at various growth periods. The hydrolysates of the polymers of the yeast extract-free medium contained more xylose than those of the yeast extract containing medium.
