A. niger SIIM M276 showed an exciting inhibitor tolerance and
gluconic acid fermentability from dry dilute acid pretreated corn
stover hydrolysate without detoxification. Increasing oxygen supply
shortened lag phase and 76.67 g/L gluconic acid with the overall
yield of 94.91% was obtained from corn stover hydrolysate. The
cellulosic sodium gluconate showed similar property as cement
additive for extension of setting time and fluidity of cement mortar.
The study suggested that lignocellulose could be an important
alternative feedstock used for future industrial gluconic acid
production.
