Perni et al. AMB Express 2013, three:66 http://www.ambexpress.com/content/3/1/ORIGINAL ARTICLEOpen AccessOptimisation of engineered Escherichia coli biofilms for enzymatic biosynthesis of LhalotryptophansStefano Perni1, Louise Hackett1, Rebecca JM Goss2, Mark J Simmons1 and Tim W Overton1AbstractEngineered biofilms comprising a single recombinant species have demonstrated outstanding activity as novel biocatalysts for a array of applications.Quinazoline-8-carboxylic acid In stock In this perform, we focused on the biotransformation of 5haloindole into 5halotryptophan, a pharmaceutical intermediate, employing Escherichia coli expressing a recombinant tryptophan synthase enzyme encoded by plasmid pSTB7. To optimise the reaction we compared two E. coli K12 strains (MC4100 and MG1655) and their ompR234 mutants, which overproduce the adhesin curli (PHL644 and PHL628). The ompR234 mutation improved the quantity of biofilm in each MG1655 and MC4100 backgrounds. In all cases, no conversion of 5haloindoles was observed making use of cells with out the pSTB7 plasmid. Engineered biofilms of strains PHL628 pSTB7 and PHL644 pSTB7 generated extra 5halotryptophan than their corresponding planktonic cells. Flow cytometry revealed that the vast majority of cells had been alive immediately after 24 hour biotransformation reactions, each in planktonic and biofilm types, suggesting that cell viability was not a significant aspect in the higher efficiency of biofilm reactions.12289-94-0 site Monitoring 5haloindole depletion, 5halotryptophan synthesis plus the percentage conversion on the biotransformation reaction recommended that there were inherent differences among strains MG1655 and MC4100, and amongst planktonic and biofilm cells, when it comes to tryptophan and indole metabolism and transport.PMID:24423657 The study has reinforced the will need to thoroughly investigate bacterial physiology and make informed strain selections when building biotransformation reactions. Key phrases: E. coli; Biofilm; Biotransformation; Haloindole; HalotryptophanIntroduction Bacterial biofilms are renowned for their enhanced resistance to environmental and chemical stresses such as antibiotics, metal ions and organic solvents when compared to planktonic bacteria. This property of biofilms is usually a cause of clinical concern, specially with implantable health-related devices (like catheters), given that biofilmmediated infections are regularly harder to treat than tho.
