영문 초록

Exclusive exposure of caffeine might bring some adverse effects to human health, and cause some risks to environment. Microbial decaffeination might be a new alternative approach because of its high specificity and efficiency. Many studies revealed that several microorganisms can degrade caffeine, including genera Alcaligenes,Rhodococcus, Klebsiella, Acinetobacter, Enterobacter, Stenotrophomonas and Pseudomonas. Biodegradation of caffeine can be significantly influenced by temperature, pH, aeration rate and initial caffeine concentration of the incubation. There are two main pathways of caffeine biodegradation: C-8 oxidation and N-demethylation, while N-demethylation is the general catabolism pathway in bacteria. Application of microbial decaffeination has also been discussed in this review.
