Macroalgae are a desirable feedstock for LA fermentation due to their high carbohydrate and low lignin content. Ulva sp., Gracilaria sp., and Sargassum cristaefolium were evaluated as a feedstock for LA fermentation. Mild acid-thermal hydrolysis (sulfuric acid concentrations?5%) resulted in superior reducing sugar recovery. Gracilaria sp. attained maximum reducing sugar recovery (0.39?g/g biomass) and lactate yield (0.94?g/g). LA fermentation of fucose-rich hydrolysate of Sargassum cristaefolium is demonstrated for the first time, with 0.81?g/g LA yield and 0.36?g/g reducing sugars. Ulva sp. attained 0.21?g/g reducing sugars and 0.85?g/g LA yield. The efficiency of macroalgae for lactate bioconversion was in the order: red macroalgae?>?green macroalgae?>?brown macroalgae. L. rhamnosus and L. plantarum could efficaciously utilize seaweed sugars for LA production. Macroalgae can potentially replace lignocellulosic biomass as a feedstock in LA fermentation.
