Summary
Halophytic plants like Typha domingensis are valuable lignocellulosic biomass sources. Thermostable cellulase from Neobacillus sedimentimangrovi UE25 efficiently saccharified this biomass, yielding significant reducing sugars for bioconversion.
Area of Science:
- Biotechnology
- Biomass Valorization
- Enzymology
Background:
- Halophytic plants offer abundant lignocellulosic biomass for bioconversion.
- Typha domingensis is a promising halophytic resource for value-added products.
Purpose of the Study:
- To investigate the enzymatic saccharification of Typha domingensis biomass using cellulase from Neobacillus sedimentimangrovi UE25.
- To optimize saccharification conditions for enhanced reducing sugar yield.
Main Methods:
- Production of Neobacillus sedimentimangrovi UE25 cellulase using Typha domingensis biomass as a substrate.
- Enzymatic saccharification of Typha domingensis cellulose.
- Optimization of saccharification parameters (temperature, enzyme units, time) using Central Composite Design.
- Analysis of structural changes using Fourier Transform Infrared spectroscopy and Scanning Electron microscopy.
Main Results:
- Cellulase production yielded 159.84 IU/mL endoglucanase when using Typha domingensis biomass.
- Initial saccharification produced 172 mg/g reducing sugars.
- Optimized conditions (60°C, 14.6 enzyme units/g, 13.4 h) yielded 610.65 mg/g reducing sugars.
- Structural modifications of the biomass were confirmed by spectroscopy and microscopy.
Conclusions:
- Typha domingensis biomass is an effective substrate for thermostable cellulase production.
- Enzymatic saccharification of Typha domingensis biomass is efficient for producing reducing sugars.
- This study supports sustainable utilization of halophytic biomass in saline environments.
