The sugar conversion efficiencies (SCE) for all the varieties and hybrids are shown in Table 4. For the varieties Wray and BJ 248 the SCE were lower for both the strains, whereas for CFTR 01 strain high SCE was observed with Keller and both the hybrids. The highest sugar conversion efficiency of 92% was observed for S. cerevisiae CFTR 01 with NSSH 104. The invertase
