Microbial Cellulose Utilization: Fundamentals and Biotechnology
- L. Lynd, P. Weimer, W. V. van Zyl, I. Pretorius

- 1 September 2002
A concluding discussion identifies unresolved issues pertaining to microbial cellulose utilization, suggests approaches by which such issues might be resolved, and contrasts a microbially oriented cellulose hydrolysis paradigm to the more conventional enzymatically oriented paradigm in both fundamental and applied contexts.
Yeast and bacterial modulation of wine aroma and flavour
Wine is a highly complex mixture of compounds which largely define its appearance, aroma, flavour and mouth-feel properties. The compounds responsible for those attributes have been derived in turn…
Tailoring wine yeast for the new millennium: novel approaches to the ancient art of winemaking

- 15 June 2000
In light of the limited knowledge of industrial wine yeasts' complex genomes and the daunting challenges to comply with strict statutory regulations and consumer demands regarding the future use of genetically modified strains, this review cautions against unrealistic expectations over the short term.
Yeast and its Importance to Wine Aroma - A Review
The importance of untapping the hidden wealth of indigenous yeast species present on grapes, and the selection and genetic development of yeast starter culture strains with improved flavour profiles are highlighted.
Expression Levels of the Yeast Alcohol Acetyltransferase Genes ATF1, Lg-ATF1, and ATF2 Control the Formation of a Broad Range of Volatile Esters

Interestingly, overexpression of different alleles of ATF1 and ATF2 led to different ester production rates, indicating that differences in the aroma profiles of yeast strains may be partially due to mutations in their ATF genes.
Flavor-active esters: adding fruitiness to beer.
Whole-Genome Comparison Reveals Novel Genetic Elements That Characterize the Genome of Industrial Strains of Saccharomyces cerevisiae
This work produces whole-genome assemblies of six commercial strains of S. cerevisiae, suggesting that, despite the scrutiny that has been directed at the yeast genome, there remains a significant reservoir of ORFs and novel modes of genetic transmission that may have significant phenotypic impact in this important model and industrial species.
Yeast modulation of wine flavor.
Muc1, a mucin-like protein that is regulated by Mss10, is critical for pseudohyphal differentiation in yeast.

It is reported that haploid and diploid starch-degrading S. cerevisiae strains were able to switch from a yeast form to a filamentous pseudohyphal form in response to carbon limitation in the presence of an ample supply of nitrogen.
Controlled Expression of the Dominant Flocculation Genes FLO1, FLO5, and FLO11 in Saccharomyces cerevisiae

The data clearly demonstrate that the flocculation behavior of yeast strains can be tightly controlled and fine-tuned to satisfy specific industrial requirements.
