Synthesis of surface active agents by Candida antarctica was considered. Based on chemical structure it was found that biosurfactants synthesized by yeast are glycolipids. Yield of glycolipid synthesis was depended on carbon source (lipids, carbohydrates) in the medium. Synthesis of biosurfactants by C. antarctica was induced by the presence of oils in the medium. During cultivation of C. antarctica in a fermenter with a medium containing soybean oil 45.49 g/dm3 of glycolipids was obtained.
Some results from structural and immunological studies of the major glycolipid from Rhodococcus equi were presented. This glycolipid showed to be a glucosylmonomycolate (GMM) with an aliphatic chain C38. Its value as taxonomic and immunodiagnostic marker was discussed.
This review summarizes the status of our knowledge on the structure, expression and function of CD1 proteins. An endosomal and non-endososomal pathways of CD1 antigen presentation are also described.
