Production of alcohol and edible yeast with extract of carob fruit

Journal Article:

Abstract

Media based on extraction from carob fruit (Ceratonia siliqua) have been used successfully in laboratory production of edible yeast and of alcohol. The fruit is a pod, 25 to 40 g, with sweet meaty flesh containing 34% sugar (dry weight), half sucrose and half invert sugar. Because of butyric acid and tannin, no antimicrobial need be added to the pulp prepared by adding H/sub 2/O (3 times weight) and autoclaving 1 hour in flowing stream. Of 3 yeast spp., Candida pulcherrima, Hansenula anomala, and Rhodotorula rubra, the latter (notable for carotenoid content) produced the most dry material in 48 hours at 32/sup 0/ on a reciprocating shaker with medium containing (NH/sub 4/)/sub 2/SO/sub 4/ 2.52 and extraction contributing 20 g reducing sugar/1. Alcohol fermentation, heretofore effected by natural microflora, was attempted with pure cultures of 4 yeast spp., Saccharomyces cerevisae (4 strains), S. oviformis (2 strains), S. beticus, and S. chevalieri. All were suitable except one strain of S. oviformis. The carob extraction had enough nitrogenous and growth substances so that no other medium ingredient was needed. With reducing sugar level t 23 g/100 mil, alcohol yield was close to the theoretical unitage (13.5) after 17-days growth. The range for  More>>
