| dc.description.abstract | Aloe vera rind (AVR), an agro-industrial by-product, contained many bioactive
compounds, which can be wasteful if improperly discharged or treated. One of the
approaches for agro-industrial waste valorization is solid-state fermentation (SSF).
This study aimed to determine the SSF and post-SSF extraction conditions for the
highest total phenolic content (TPC) in AVRE and the subsequent antibacterial and
surface disinfection capability of fermented AVRE. The optimal conditions for SSF were
identified at temperature of 32 °C, a moisture content of 60%, and a fermentation
duration of 5 days. The post-SSF extraction conditions were determined as 105 mins
with temperature at 45°C, solid to solvent ratio (SSR) at 1:15, and ethanol 70%. At
optimal conditions, the fermented AVRE had higher TPC than unfermented AVRE. In
addition, the change in phytochemical compositions after SSF was evaluated. Besides,
mycotoxins were undetectable in fermented AVRE. In accordance with the improved
TPC, the antibacterial effectiveness of fermented AVRE was also elevated, as
demonstrated by a reduction in the minimum inhibitory concentration (MIC) value.
Moreover, fermented AVRE was more efficient than unfermented AVRE in reducing
surface microorganisms. Overall, the study suggested that SSF was an effective
technique for improving the TPC, antibacterial activities and surface disinfectant
potential of AVRE | en_US |
