Show abstract
An integrated biorefinery for ethanol and lactic acid production from the biomass of cyanobacterium Arthrospira platensis was investigated. Different pretreatments consisting of supercritical fluid extraction (SFE) and microwave assisted extraction (MAE) with non-polar (MAE-NPS) and polar solvents (MAE-PS) were tested on cyanobacterial biomass to obtain bioactive metabolites and the resulting residual biomass was used as a substrate for fermentation with Saccharomyces cerevisiae LPB-287 and Lactobacillus acidophilus ATCC 43121 to produce ethanol and lactic acid, respectively. The maximum concentrations achieved in our processes were 3.02{+/-}0.07 g/L of ethanol by the MAE-NPS process at 120 rpm 30 {degrees}C, and 9.67{+/-}0.05 g/L of lactic acid by the SFE process at 120 rpm 37 {degrees}C. Our results suggest that the proposed approach can be successfully applied in bioactive metabolites extraction and subsequently in the production of Ethanol and Lactic acid from A. platensis depleted biomass.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
