| Abstract: | The production of protein-enriched feed directly fermenting from sweet potato by submeged andsolid-state culture using amylolytic yeast (Sacharomycopis fibuligera AS2. 1145 ) was studied. Underoptimum condihons, the adult of batch in 2 L fermentor for 38 h were as folloWS: dxy matterweight was 25. 2 g/L, which contained 34.0% czude protein; utilizahon ratiO of suger was 68. 3%.Final pnduct contained 20 .0% crude protein by solid-state fennentation for 72 h. |
