In vitro fermentation study demonstrates efficient succinic acid production from wheat straw hydrolysate by Actinobacillus succinogenes, highlighting sustainable chemical synthesis.
Key Points
To optimize the fermentation medium composition for the bioconversion of wheat straw hydrolysate into succinic acid using Actinobacillus succinogenes.
Tested two dilutions of hydrolyzed wheat straw (50% and 90% v/v) as the primary carbon source.
Evaluated yeast extract supplementation at 10 and 25 g·L⁻¹ alongside magnesium carbonate buffering agent at 30 and 60 g·L⁻¹ in various combinations.
Achieved a peak succinic acid concentration of 12.87 g·L⁻¹ with an overall yield of 62.1%.
Identified optimal fermentation conditions as 90% (v/v) hydrolysate supplemented with 10 g·L⁻¹ yeast extract and 60 g·L⁻¹ magnesium carbonate.
