Erythritol Production by a Yeastlike Fungus.
A yeastlike fungus, probably belonging to the genus Torula, was isolated from fresh pollen and was shown to produce erythritol in yields of 35 to 40% of the sugar utilized. The ability to produce erythritol is an inherent characteristic of the isolate, but unfavorable fermentation conditions can lead to the production of glycerol at the expense of erythritol. By the use of a synthetic medium, i...
متن کاملLipid and citric acid production by wild yeasts grown in glycerol.
In this study, crude glycerol was used as a carbon source in the cultivation of wild yeasts, aiming for the production of microbial lipids and citric acid. Forty yeasts of different sources were tested concerning their growth in crude and commercial glycerol. Four yeasts (Lidnera saturnus UFLA CES-Y677, Yarrowia lipolytica UFLA CM-Y9.4, Rhodotorula glutinis NCYC 2439, and Cryptococcus curvatus ...
متن کاملProduction of Food Grade Yeasts
Yeasts have been known to humans for thousands of years as they have been used in traditional fermentation processes like wine, beer and bread making. Today, yeasts are also used as alternative sources of high nutritional value proteins, enzymes and vitamins, and have numerous applications in the health food industry as food additives, conditioners and flavouring agents, for the production of m...
متن کاملProduction of xylitol by yeasts
Xylitol is a naturally occuring sugar alcohol, which is currently produced chemically on a large scale. In recent years the bioconversion of D-xylose from lignocellulosic residues into xylitol, gained an increased attention as an alternative procedure , due to its high efficiency and reduced cost of such technology. The biotechnological method of producing xylitol involves microorganisms that a...
متن کاملProduction of pectic enzymes in yeasts.
When grown in the appropriate medium, several yeast species produce pectinases able to degrade pectic substances. It is mainly exocellular endopolygalacturonases that break pectins or pectate down by hydrolysis of alpha-1,4-glycosidic linkages in a random way. Biochemical characterisation of these enzymes has shown that they have an optimal pH in the acidic region and an optimal temperature bet...
