Aglycone isoflavones are estrogen-like bioactive compounds found in low amounts in soybean, which are increased by biotransformation processes. This study investigated two biotransformation processes of soybean extracts with Aspergillus awamori fungus, evaluating aglycone content and capability of stimulation of collagen-I deposition. Isoflavones were quantified via HPLC; cytotoxicity of biotransformed extracts toward mouse and human fibroblasts was evaluated via NRU and apoptosis/necrosis assays; and collagen-I deposition was measured through Western blot, immunofluorescence, and immunoassay. BSE-2 was the biotransformed soybean extract with the highest aglycone content and did not decrease viability or demonstrated cytotoxicity to either L929 or HDFa cells. BSE-2, at the optimal concentration of 1.33 mu g/mL, increased substantially collagen-I amount in HDFa intracellular matrix compared to non-biotransformed soybean extract (NBSE) and immunoassay demonstrated that the extracellular deposition was mostly inhibited by BSE-2 concentrations, except at 1.33 mu g/mL. Hence, biotransformed soybean extract by the enzymatic filtrate of Aspergillus awamori fungus demonstrated a high nutricosmetic potential, showing safeness and effective collagen-I augmentation.
