摘要：
The degree of protein enrichment of sweet potato residue by different amylolytic moulds in solid-state cultivation was much greater than that obtained using amylolytic yeasts. The optimum initial moisture content for protein enrichment was about 65% (w/w). Adding nitrogen sources to the culture twice (at the start of the incubation and after 24 h) considerably improved the final protein content. A co-culture of amylolytic mycelial fungi yielded a product with 32% (w/w) crude protein after 4 days' incubation at 30-degrees-C. In a column reactor, the highest temperatures reached were 42-degrees-C and 40-degrees-C and the minimum O2 concentrations were 1.5% and 2.5% of full saturation in the central and bottom layers, respectively.
