Caffeine degradation in solid state fermentation by Aspergillus tamarii: effects of additional nitrogen sources

Potential for biodegradation and sorption of acetaminophen, caffeine, propranolol and acebutolol in lab-scale aqueous environments

“…The concentration of caffeine in the sorption-only system decreased by 76% within 13 days and subsequently remained stable, while all of the caffeine in the combined sorption-biodegradation system was consumed by the fourth day (t 1/2 = 1.5 days). Caffeine biodegradation has been documented in single culture [25,26], mixed consortium [27] and in wastewater treatment plants (WWTPs) that used biological treatment systems [15,28]. Santos et al [15] monitored several pharmaceutically active compounds over a one-year period in the influents and effluents of WWTPs and found that more than 80% of the caffeine had been removed by the stipulated hydraulic retention time.…”

Catabolic pathways and biotechnological applications of microbial caffeine degradation

“…1. The metabolites formed thereafter have not been reported probably because the intermediates formed are rapidly metabolized (Hakil et al 1999).…”

Solid state cultivation — an efficient method to use toxic agro-industrial residues

“…If the toxic constituents could be removed, or at least degraded to a reasonably low level, it would open new avenues for their utilisation. There are some reports describing degradation of caffeine in different media such as synthetic medium, roast coffee infusion and coffee pulp (SCHWIMMER and KURTZMAN 1972, PORRES et al 1993, ROUSSOS et al 1994, HAKIL et al 1998, HAKIL and AUGUR 2000.…”
