show Abstracthide AbstractThe CES strain was isolated from soil at the University of Iowa Center for Biocatalysis and Bioprocessing using an enrichment procedure with caffeine as sole carbon and nitrogen source. Prior to isolation, coffee grounds had been amended to the soil for ten days. The soil was then collected and incubated in M9 minimum medium with .25 percent caffeine as described previously previously (Yu CL, Louie TM, Summers R, Kale Y, Gopishetty S, Subramanian M. J Bacteriol. 2009 Jul;191(14):4624-32. Epub 2009 May 15.) The strain was initially characterized as Pseudomonas sp. Strain CES (for Coffee Enriched Soil) based on 16S rRNA sequencing and FAME analysis. CES uses the N-demethylation pathway for caffeine breakdown.
