This study investigated the nutritional quality of soybean meal (SBM) fermented by Aspergillus (FSBMA) and/or
followed by Lactobacillus fermentation (FSBMA+L). Both fermented products significantly improved protein utilization of SBM with
higher trichloroacetic acid (TCA) soluble true protein content, in vitro protein digestibility and available lysine content, especially in
FSBMA+L. Moreover, FSBMA+L produced a huge amount of lactic acid resulting in lower pH as compared to the unfermented SBM or
soybean protein concentrate (SPC) (p
