Methodologies and Applications of Proteomics for Study of Yeast Strains: An Update.

Yeasts are one of the mostly used microorganisms as models in several studies. A wide range of applications in different processes can be attributed to their intrinsic characteristics. They are eukaryotes and therefore valuable expression hosts that require elaborate post-translational modifications.

Continuous ethanol production in a nonconventional five-stage system operating with yeast cell recycling at elevated temperatures.

Three ranges of increasing temperatures (35-43, 37-45, 39-47 degrees C) were sequentially applied to a five-stage system continuously operated with cell recycling so that differences of 2 degrees C (between one reactor to the next) and 8 degrees C (between the first reactor at the highest temperature and the fifth at the lowest temperature) were kept among the reactors for each temperature range. The entire system was fed through the first reactor. The lowest values of biomass and viability were obtained for reactor R(3) located in the middle of the system.

Nineteen childhood near drowning cases admitted to a private general hospital from December 31, 1983 through out December 1987 at a mean age of 2 years 3 months are discussed. All patients had diagnosis when first found by relatives, 16 were apneic and only 11 received some kind of resuscitation which complied with accepted standards in 4 of them. Seven cases were admitted in stage A of Conn, two in stage B and ten in stage C.
