Abstractbeta-poly(L-malic acid) (PMLA) production by Aureobasidium pullulans ipe-1 using Jerusalem artichoke tuber (JA) hydrolysate as a low cost carbon source was developed. The PMLA production was favored by JA pretreated with 0.06 M nitric acid without adding exogenous nitrogen sources into fermentation medium. With an initial 130 g/L total sugar of the JA hydrolysate, the highest PMLA productivity 0.52 g/L.h was achieved, which was increased by 2.0 folds compared to that with sole glucose case. To further enhance PMLA productivity, the cells were immobilized in luffa sponge matrices, and repeated batch culture was carried out for 4 cycles. The resulting PMLA productivity was further enhanced by 50% compared with the batch culture. The cost of PMLA production in the JA case was only 5.4% of that in the glucose case. The outcomes of this work provided a strategy of PMLA production on a commercial scale.
