Microbial cellulase production and its potential application for textile industries

Annals of Microbiology, Journal Year: 2023, Volume and Issue: 73(1)

Published: April 10, 2023

Abstract Purpose The textile industry’s previous chemical use resulted in thousands of practical particulate emissions, such as machine component damage and drainage system blockage, both which have implications. Enzyme-based processing is cost-effective, environmentally friendly, non-hazardous, water-saving. purpose this review to give evidence on the potential activity microbial cellulase industry, mostly confined realm research. Methods This was progressive by considering peer-reviewed papers linked production, its prospective application for industries appraised produced develop assessment. Articles were divided into two categories based results trustworthy educational journals: methods used produce diversity microorganisms through fermentation processes approaches microbes fermentation. Submerged (SMF) solid-state (SSF) techniques are currently being meet industrial demand production bio industry. Results Microbial vital increasing day due no side effect environment human health becoming increasingly important. In conventional processing, gray cloth subjected a series treatments that involved breaking dye molecule’s amino group with Cl − , started accelerated dye(-resistant) bond cracking. A enzyme primarily derived from variety species found various ecological settings biotextile/bio-based product technology future needs applications. Conclusion Cellulase has been advantages cellulose-based textiles, well quality enhancement fabric maintenance over traditional approaches. Cellulase’s role industry chosen an appropriate sound solution long healthy lifestyle.

A Review on Reinforcements and Additives in Starch-Based Composites for Food Packaging

Polymers, Journal Year: 2023, Volume and Issue: 15(13), P. 2972 - 2972

Published: July 7, 2023

The research of starch as a matrix material for manufacturing biodegradable films has been gaining popularity in recent years, indicating its potential and possible limitations. To compete with conventional petroleum-based plastics, an enhancement their low resistance to water limited mechanical properties is essential. This review aims discuss the various types nanofillers additives that have used plasticized including nanoclays (montmorillonite, halloysite, kaolinite, etc.), poly-saccharide (cellulose, starch, chitin, chitosan nanomaterials), metal oxides (titanium dioxide, zinc oxide, zirconium essential oils (carvacrol, eugenol, cinnamic acid). These reinforcements are frequently enhance several physical characteristics properties, thermal stability, moisture resistance, oxygen barrier capabilities, biodegradation rate, providing antimicrobial antioxidant properties. paper will provide overview development starch-based nanocomposite coatings applied food packaging systems through application additives.

Advances in drug delivery applications of modified bacterial cellulose-based materials

Frontiers in Bioengineering and Biotechnology, Journal Year: 2023, Volume and Issue: 11

Published: Aug. 4, 2023

Bacterial cellulose (BC) is generated by certain species of bacteria and comprises polysaccharides with unique physical, chemical, mechanical characteristics. Due to its outstanding biocompatibility, high purity, excellent strength, water absorption, highly porous structure, bacterial has been recently investigated for biomedical application. However, the pure form hardly used as a material due some inherent shortcomings. To extend applications in drug delivery, modifications native are widely improve properties. Usually, can be carried out biological methods. In this review, brief introduction production fabrication first given, followed up-to-date in-depth discussions modification. Finally, we focus on potential delivery system.

Bacterial Cellulose Nanofibers Modified with Quaternary Ammonium Salts for Antimicrobial Applications

ACS Applied Nano Materials, Journal Year: 2023, Volume and Issue: 6(6), P. 4854 - 4863

Published: March 2, 2023

Nanofibrillated bacterial cellulose (NFBC) is a recyclable, biodegradable, and nontoxic biopolymer whose fibers are much longer than other nanofibers prepared from wood pulp. NFBC promising material for use as an additive in food pharmaceutical industries nanofiller fiber-reinforced nanocomposite resins; however, it easily microbially degraded and, consequently, cannot be used long-term applications. In this study, was endowed with antimicrobial properties through modification by aqueous alkaline solution of 2,3-epoxypropyltrimethylammonium chloride (EPTMAC). The structure the modified analyzed detail using solid-state NMR infrared spectroscopy, well X-ray diffractometry, which revealed that only surface layer each fiber had been conjugated quaternary ammonium EPTMAC groups, amount added during preparation determining degree molar substitution (MS) cationic groups. addition, increasing MS resulted positive charge led to increase transparency nanofiber dispersion owing electrostatic repulsion between nanofibers. Despite these differences, morphologies crystal structures were almost identical those pristine NFBC, suggesting selectively reacts hydroxyl groups NFBC. cell culture experiments against Klebsiella pneumoniae, Gram-negative bacterium, most likely because positively charged.
