Cellulolytic enzymes produced by spore-forming bacteria seem to be a potential solution to the degradation of lignocellulosic waste. In this study, several dozen bacterial spore-forming strains were isolated from soil and one of them was selected for further studies. The studied bacterial strain was identified to genus Bacillus (strain 8E1A) by 16S rRNA gene sequencing. Bacillus sp. 8E1A showed an activity of carboxymethyl cellulase (CMCase) with visualization with Congo Red-25 mm (size of clear zone). To study CMCase, filter paper hydrolase (FPase), and microcrystalline cellulose Avicel hydro

Abstract:

Microcrystalline cellulose (MCC) from bamboo is a natural biodegradable polymer that can be applied as barrier materials in the form of films. Bamboo contributes to 90% of the total mass of the dry weight comprised of cellulose, hemicellulose, and lignin. In this study, Gigantochloaalbociliata (Buluh Madu) was chosen due to the fast-growing species, cheaper and abundance in Malaysia. This bamboo was undergone Kraft pulping process to get the pure cellulose and then continued with the acid hydrolysis process to produce microcrystalline cellulose (MCC).

AbstractCrosslinked natural rubber (NR)/microcrystalline cellulose (MCC) composite was prepared by dry mixing of NR with MCC extracted from cotton fiber. MCC was first extracted from cotton fiber by acid hydrolysis processing, then applied to block natural rubber as a reinforcement. MCC grafted maleic anhydride (MA) was also synthesized and applied to the composites to improve the compatibility between natural rubber and cellulose. Obtained cellulose samples were subjected to infrared spectroscopy (FTIR) to confirm the purity of cellulose structure and the presence of MA grafted on MCC chains.

In geotechnical engineering, the enhancement of soil properties is crucial for cost-effective construction practices. This study investigates the impact of incorporating microcrystalline cellulose into styrene-butadiene emulsion modified cement-stabilized soils. The mechanical properties, including unconfined compressive strength (UCS) and indirect tensile strength (ITS), were evaluated alongside morphological analysis using scanning electron microscopy. Results indicate that the addition of microcrystalline cellulose influences the mechanical behavior of the composite material in a nuanced ma
