Summary: In this study, a cutinolytic fungus was isolated from the soil and identified as belonging to the genus Fusarium, specifically Fusarium verticillioides, based on 18s rDNA sequencing. The composition of the medium for enhanced cutinase production was optimized using classical and statistical methods. The optimized conditions resulted in a 14.57-fold increase in enzyme activity, with a maximum cutinase activity of 626.6 IUml(-1).

Summary: This research optimizes fermentation modification and papain enzymes for manufacturing virgin coconut oil. Through experimentation, it was observed that the addition of crude papain enzyme (CPE) and longer fermentation time increased the yield of virgin coconut oil. The optimal conditions for maximum yield and quality were obtained with a mass of crude papain enzyme of 993.5 mg and a fermentation time of 60 h.

Summary: In this study, a potent keratinolytic isolate, identified as Bacillus thuringiensis, was optimized for feather degradation using response surface methodology. The results showed that complete feather degradation and protein-rich hydrolysates could be obtained by supplementing the feather meal broth with glucose and adjusting the pH. The hydrolysates contained carboxyl and amino groups, indicating the presence of peptides and amino acids.

Summary: Chloride ions, which are omnipresent environmental pollutants, have devastating and irreversible effects on sustainable water ecosystems worldwide. This study employed bismuth oxide as an antichlor to effectively remove chloride, and conducted systematic investigations to assess the factors affecting dechlorination. The response surface methodology was used to optimize the dechlorination process, and various characterization techniques were employed to determine the composition and morphology of the dechlorinated products. The results showed that response surface methodology is a reliable approach for optimizing dechlorination parameters and improving the removal performance of almost non-removable chloride.
