英文摘要	Membrane-assisted beta-poly(L-malic acid) (PMLA) production from bagasse hydrolysates was developed. For the first time, it was found that mixing the acid and enzyme hydrolysates was unfavorable for PMLA production because too high hexose: pentose ratio and glucose concentration in the mixed sugar could inhibit the assimilation of pentose. 120 g/L sugar concentrations in the acid hydrolysate was suitable for PMLA production with 23.2 g/L PMLA and 34.7 g/L biomass. Moreover, an integrated membrane process consisting of ultrafiltration, nanofiltration and reverse osmosis membranes could concentrate sugars and adjust acetic acid concentration prior to fermentation of lignocellulosic sugars. Meanwhile, it was found that 1.46 g/L acetic acid was preferred for PMLA production from enzyme hydrolysate or sole glucose which respectively increased PMLA production and cell growth by 25.4% and 5.9% from sole glucose, while it showed no significant enhancement in PMLA production with a higher cell growth and productivity from acid hydrolysate.
