“…The brewer's bottom yeast possesses scarcely half of the acid phosphatase activity found in commercial baker's yeast (Suomalainen et al, 1960 ). Acid phosphatases have also been studied in the other conventional yeast Schizosaccharomyces pombe (Dibenedetto and Cozzani, 1975 ;Schweingruber et al, 1986 ); in several non-conventional yeasts like Arxula adeninivorans (Buttner et al, 1991 ;Minocha et al, 2007 ), Yarrowia lipolytica (Lopez and Dominguez, 1988 ), Kluyveromyces lactis (Altikrete et al, 1984 ), Candida albicans (Odds and Hierholzer, 1973 ), as well as in the methylotrophic yeasts, Hansenula polymorpha (Phongdara et al, 1998 ) and Pichia pastoris (Payne et al, 1995 ). Several investigations have also been carried out on the role of yeasts (conventional like S. cerevisiae as well as various non-conventional yeasts) in phytate degradation [Table 31.2 ].…”
