Caffeine degradation by food microorganisms

6 Aerobic Degradation by Microorganisms

Caffeine Degradation by Yeasts Isolated from Caffeine Contaminated Samples

Five yeast species isolated from caffeine contaminated samples were screened for their capability of caffeine degradation. Based on the degradation efficiency, isolate was selected and identified as Trichosporon asahii which showed 60 % degradation of caffeine in 72 hours when caffeine was utilized as the sole carbon and nitrogen source. The influence of various factors such as pH, temperature,...

Enhanced degradation of isofenphos by soil microorganisms

Laboratory experiments were conducted to investigate the enhanced degradation of isofenphos [ 1methylethyl 24 [ethoxy[ (1-methylethyl)amino]phosphinothioyl]oxy] benzoate] in soil and to elucidate the microbiology of this phenomenon. [U-ring-'4CIIsofenphos was most rapidly degraded in Iowa cornfield soils that had a history of isofenphos insecticide use. Between 13 and 42% of an applied dose of ...

Catabolism of caffeine in plants and microorganisms.

Caffeine has been found in tissues of several plants. Because of its stimulating effect on the central nervous system, a great number of reports have been published on its content in beverages and foodstuffs. However, a much more restricted number of reports have dealt specifically with caffeine metabolism in plants. This review presents, in chronological manner, the contribution of these repor...
