41. Hi i recently did a biological experiment investigation, involving different respiratory substrates for yeast cells Saccharomyces cerevisiae. 42. There are currently seven species in this genus including the type species Saccharomyces cerevisiae virus L-A. 43. The first yeast expression platform was based on the baker s yeast " Saccharomyces cerevisiae ". 44. The yeast species " Saccharomyces cerevisiae " has been used in baking and infection in humans. 45. It is also present in other species including humans, but not " Saccharomyces cerevisiae ". 46. The yeast " Saccharomyces bulderi " can be used to ferment gluconolactone to ethanol and carbon dioxide. 47. The first signaling scaffold protein discovered was the Ste5 protein from the yeast " Saccharomyces cerevisiae ". 48. Once the starch is converted to sugar it can be readily fermented by " Saccharomyces cerevisiae ". 49. The protein encoded by this gene shares the sequence similarity with Xenopus importin-alpha and Saccharomyces cerevisiae Srp1. 50. This protein is similar to a Saccharomyces cerevisiae protein that participates in meiotic segregation fidelity and crossing-over.
