Biodegradation of deproteinized potato wastewater and glycerol during cultivation of Rhodotorula glutinis yeast Electron. J. Biotechnol.
Kot,Anna Maria; Blazejak,Stanislaw; Kurcz,Agnieszka; Gientka,Iwona.
Background Deproteinized potato wastewater and glycerol are two by-products which are difficult to dispose. The objective of this study was to determine the ability of Rhodotorula glutinis to use glycerol and nitrogen compounds present in deproteinized potato wastewater and to evaluate the ability of simultaneous biodegradation of potato wastewater and glycerol via microbiological methods. Results It has been found that R. glutinis used glycerol and potato wastewater as a source of carbon and nitrogen, respectively. The highest degree of glycerol content (70.6%) reduction was found after cultivation of the investigated strain using a medium with 5% glycerol. In this medium, a significant reduction in the total protein content, estimated at 61%, was...
