Summary: The aim of this study was to isolate and identify a highly efficient cellulolytic bacteria strain that can be used in acidic environments for the effective utilization of agricultural waste. A strain labeled as B13-2 with high cellulase production was screened and identified as Raoultella terrigena. The culture conditions of strain B13-2 were optimized, and it was found that the optimum conditions resulted in a 140% increase in cellulase activity compared to before optimization. Strain B13-2 showed higher cellulase production when rice straws were used as the natural carbon source, and exhibited a stronger ability to degrade cellulose under acidic conditions.

Summary: This research introduces a new and eco-friendly method to create multifunctional nanobiocomposites which can efficiently remove toxic heavy metals and dyes, as well as disinfect microorganisms in wastewater. The nanobiocomposites (KAC-CS-AgNPs) were made by incorporating photochemically generated silver nanoparticles into a chitosan-modified activated carbon derived from kenaf, using a unique self-activation method. The experiment results demonstrated exceptional adsorption efficiency for copper, lead, and Congo Red dye, as well as potent antibacterial activity against Staphylococcus aureus and Escherichia coli. The synthesized nanocomposite has great potential for commercial applications. Rating: 9/10.

Summary: The study aimed to investigate cellulase production from coconut-mesocarp by the bacterial strain FW2 isolated from kitchen food waste in South Korea. The strain exhibited tolerance to a wide range of temperature, pH, and high salt concentrations. Optimal enzyme activity conditions were found to be 40-50 degrees C, pH 7.0-7.5, and 0-10% NaCl, resulting in high levels of CMCase, Avicelase, and FPase activities. The results suggest that enzyme production by strain FW2 may have significant commercial values for various applications including industry and waste treatment.

Summary: The feasibility of microalgal biomass as a promising and renewable source for biofuel production is extensively studied. Microalgal biomass can be cultivated under various conditions, including photoautotrophic, heterotrophic, photoheterotrophic, and mixotrophic cultivation. Mixotrophic cultivation shows higher biomass productivity and yields more polyunsaturated fatty acids compared to photoautotrophic cultivation. The use of industrial wastewaters for mixotrophic cultivation can reduce contaminants' load while producing productive microalgal biomass. This review focuses on sustainable cultivation of microalgae in different types of wastewaters.
