TL;DR: The results indicated that the recombinant enzymes of BGL1 displayed a 2–4-fold increase in their hydrolytic activity toward cellulosic substrates like avicel, amorphous cellulose, bacterial microcrystalline cellulOSE, and carboxy methyl cellulose in comparison with the native enzyme.
Journal ArticleDOI
Olfaction and taste: Human perception, physiology and genetics
TL;DR: A timely summary of some key developments in the understanding of odorant and tastant detection is offered, and how genetic components in human olfaction might be utilised to develop a ‘biosensor’ for aroma detection and discrimination is considered.

Wine and health.
TL;DR: Armstrong et al. as mentioned in this paper, G. O., et al., 2001. wine and health : research in action. South African Journal of Science, 97(7-8):279-282.
Journal ArticleDOI
Cellular differentiation in response to nutrient availability: The repressor of meiosis, Rme1p, positively regulates invasive growth in Saccharomyces cerevisiae.
TL;DR: It is shown that Rme1p positively regulates invasive growth and starch metabolism in both haploid and diploid strains by directly modifying the transcription of the FLO11 and STA2 genes, which encode a cell wall-associated protein essential for invasive growthand a starch-degrading glucoamylase, respectively.
