Vanillin Genes

Sam5 & Sam8

  • Saccharothrix espeanensis has arrived from DSMZ culture collection
requires reviving and fcs and ech genes being PCR'd out
  • Sam8 and Sam5 expression vector kindly donated by Dr Anton Linnenbrink from the Institute for Pharmazeutische Wissenschaften in Germany
vector has been transformed into E. coli
need to PCR out genes when primers arrive

COMT

  • have grown up alfalfa seeds and genomic plant DNA has been extracted
attempted to amplify up COMT via PCR, but have had no promising results so far
  • RNA has been isolated from alfalfa
have attempted to amplify up cDNA of COMT gene and are waiting on results

fcs & ech

  • Pseudomonas fluorescens has arrived from NCIMB culture collection and has been revived

fcs

  • have carried out several PCRs to amplify out the fcs gene from Pseudomonas fluorescenes
PCRs did not result in one PCR product being produced, problem is most probably due to the P. fluorescens genome being of high GC content
are attempting to purify out fcs gene from agrose gel of PCR products

ech

  • the first set of primers ordered for ech did not work, as no PCR product was present after several PCR reactions
  • have sent away for a second set of primers and are awaiting their arrival


vector

  • we are going to modify a vector kindly donated by Norwich University, which can act as a shuttle vector between E. coli and a broad range of gram positive hosts, including Bacillis subtillis, Lactobacillus and Lactococcus
  • firstly we will ligate MITs wintergreen scent generating device into the vector to characterise how the vector works in our chosen gram positive organisms
  • secondly, when we have a working vanillin synthesis pathway, the vanillin biosynthesis pathway will be inserted into the vector and then transformed into Lactobacillus under the control of the arabinose promoter
Lactobacillus may then be used to make yoghurt giving us self flavouring yoghurt, when the arabinose inducer is added
