Moreover, cane molasses (3.5-17.5% w/v total sugar) and yeast powder (1.5-5% w/v) were used as alternative nutrients for both strains' cultivation. These media were formulated for analysis of cellular growth, P-Fructosyltransferase and Fructooligosaccharides (FOS) production. Transfructosylating activity (U-t) and FOS production were analyzed by HPLC. The highest enzyme production by both the strains was 3% (w/v) sucrose and 3% (w/v) peptone, or 3.5% (w/v) total sugars present in cane molasses and 1.5% (w/v) yeast powder. Cane molasses and yeast powder were as good as sucrose and peptone in the enzyme and FOS (around 60% w/w) production by studied strains.1003-1009engFructooligosaccharidesAspergillus japonicusAspergillus nigercane molassesyeast powderArtigo10.1007/s10295-006-0152-xWOS:000243075200004Acesso restrito
