Potential of Microbial-decaffeination Process: A Review

Caffeine is described as an essential naturally occurring, viable, and marketable purine alkaloids which can be degraded by bacteria; the competence of bacteria to use caffeine as its sole source of carbon and nitrogen has been elucidated more than four decades ago. This paper presents a review of the potential of microbial decaffeination process using standard techniques of harvesting recent and appropriate information and data from Online and Library sources focusing on to bacterial caffeine degradation processes: N-demethylation and C-8 oxidation. These two processes were observed to be more efficient, safe, specific, and economically crucial to caffeine degradation. Various organisms have been isolated across the globe that are capable to degrading caffeine such as Klebsiella, Rhodococcus, Alcaligenes, Serratia, Phanerochaete, and Bacillus sp. Furthermore, innumerable biotechnological application of the bacterial caffeine degradation has been identified such as bioremediation of caffeine-polluted environment, bio-decaffeination, chemical production, and diagnostic tools.
