Because of the high variability of yeast species and their population sizes, and the difficulty in microbial profiling of fermentation, few studies have reported on wine chemical composition (Beh et al. 2006). General characteristics are recorded in Table 8D.5. These data suggest that the diminished role of Saccharomyces allows some of the mn-Saccharomyces characteristics to be more evident and to...

Murrah buffaloes fed on a diet of wheat straw and concentrate mixture (50 50) and supplemented with a feed additive (a mixture of Allium sativum, 1% and Mentha piperita oil, 0.1% of DMI) (Mix 1) on every alternate day resulted in 7% reduction in methane emission (l/kg DMI), but this reduction in methane emission was attributed to reduction in dry matter intake (Verma et al. 2009). There was no adverse effect on rumen fermentation pattern, enzyme and microbial profiles. 

In another experiment, a mixture of three plants (Mix 3) fed to buffalo calves at the rate of 1%, 2% and 3% of DMI, resulted in a dose dependent inhibition in methane emission (l/kg DDM) since per cent inhibition increased with an increase in dose of the feed additive (Chaudhary et al. 2009) without affecting dry matter digestibility at any of the levels of feed additives tested. The VFA and fibre degrading enzyme activities were not affected, whereas, there were a few changes in the rumen microbial profile as estimated by real time-PCR, but these were not responsible for any significant change in rumen fermentation.

Profiling of VOC emissions from different strains of Escherichia coli, Klebsiella, Cit-robacter, P aeruginosa. Staphylococcus aureus and H. pylori was performed in an in vitro study by Lechner etal. [19], In agreement with the earlier microbial profiling based on VOC emissions by Critchley et al., the work by Lechner and co-workers showed substantial differences in the mass spectral patterns between the various microbial cultures. Furthermore, certain m/z ions were associated with specific bacteria, an observation that provided further support for the idea that the analysis of VOC emissions from bacteria using PTR-MS could be used to differentiate bacterial strains in vitro.
