Microbial synthesis of fat by means of the RHODOTORULA GRACILIS yeast.Peer-reviewed article

R. PRAUS, J. PROTIVA, J. DYR

The article deals with the possibility of utilizing raw materials which have been so far lost as waste products of plants manufacturing glucose from starch. Since the dextroner (hydrol) does not practically contain any nitrogen, it is extremely suitable for microbial synthesis of far through the Rhodotorula Gracilis yeast. It can be reasonably expected, that after the yeast have adapted themselves to the dextroner (hydrol) the same results can be achieved as with glucose i.e. the far coefficient well over 22% and far content in the yeast dry matter over 70%. Experiments have been made on a laboratory scale to determine the relation between the duration of fermentation and fat yield. Conclusion can be made, that the microbial synthesis of fat, provitamin A, torulen (suitable for food industry as a dyestuff) and provitamin D should be given full attention.
