✦ Synopsis

An amylolytic yeast strain identified as Saccharomyces cerevisiae was isolated from yam tuber. Studies on the effect of physical agents such as pH and temperature on the activity of the amylase showed that the optimum pH and temperature for the amylase produced by the S. cerevisiae were 5.0 and 60 "C, respectively. Heavy metal resistance study on the amylolytic yeast strain indicated different levels of resistance to copper (6.0 m), zinc (3.0 m) and manganese (15.0 m) ions. The results are discussed in relation to the potential use of an amylolytic yeast in the brewing industry in Nigeria.
