“The Effect of VFA as a sole carbon source on lipid accumulation by Cryptococcus albidus for
Biodiesel production.”
Volatile fatty acids produced from anaerobic digestion of food waste in an anaerobic digester operating at
37oC and an HRT of 2 days, were used as the sole carbon source for the accumulation of intracellular lipids
by Cryptococcus albidus. Lipids were then extracted and transesterified into biodiesel. Yeast cultures were
grown in an aerobic 6.0 L batch reactor at 23 C and pH 6.0 with ammonium chloride as the nitrogen source.
Cryptococcus albidus was also grown using pure acids with the fermenter VFA composition (succinic:
acetic: propionic: valeric 1.2: 3.8: 4.1: 0.9) and with VFAs (acetic, propionic, butyric acids) in a ratio of
6:1:3. The lipid yield was found to be 0.098 g/g VFA and 0.06 g/g VFA respectively. The highest lipid
content (19.7%) was obtained on pure acids with the fermenter VFA composition.

“Multiplex genotyping of the p53 gene using solid phase capturable dideoxynucleotides and mass
spectrometry.”
In this study, MALDI-TOF based Single Base Extension (SBE) method with and without solid phase
capture (SPC) was used for the genotyping of potential point mutation sites in the exon 8 of a synthetic p53
gene template and exons 11, 25 and 34 of the human sorlitin based gene, SORL A, mutation of which for
apolipoprotein E (APOE) is predictive of Alzheimer’s disease. Lack of APOE receptor is suspected to be a
contributory factor to Alzheimer’s: a significant reduction in SORL1 expression has been found in the brain
tissue of Alzheimer’s disease patients.
Manipal University: January-May 2011
“A Comparison of Lipase yield of the wildtype and mutant Bacillus subtilis strain in different
reactor operation modes”
The effect of different reactor operation modes on the lipase yield from mutant and the wildtype strain of B.
Subtilis were studied.The optimum media composition for lipase production was determined through shake
flask culture studies. Batch studies were performed on both the wildtype and UV mutated strains, while fed-
batch and continuous reactor was studied only for the wildtype strain. A mathematical model for lipase yield
in batch mode was also proposed, optimized and validated.
