Motivated by the negative impact of fossil fuel consumption on environment, need arises to produce materials and energy from renewable sources. Cellulose, main biopolymer Earth, plays a key role in this context, serving as platform for development biofuels, chemicals novel materials. Among latter, micro- nanocellulose have been receiving increasing attention last few years. Their many attractiv...

AIMS The effect of synthetic media on the submerged mycelial growth and exo-biopolymer production in various edible mushrooms was investigated in shake flask culture. METHODS AND RESULTS Among 19 mushrooms examined, the relatively high yield in mycelial biomass and exo-biopolymer production was achieved in potato malt peptone (PMP) medium. In particular, Ganoderma lucidum NO. 1 and Phellinus ...

Agriculture waste such as sugarcane bagasse (SCB) is composed mostly of cellulose, a very versatile natural biopolymer with well-established applications in many industries. The purpose this study was to use combination treatment methods which include alkaline and mild acid hydrolysis assisted ultrasonication extract cellulose nanofibers (CNFs) from bagasse. Initially, the SCB fibers were treat...

Root knot nematode, Meloidogyne spp. causes severe yield losses in vegetable crops. Chitosan is one of the most abundant biopolymer available worldwide next to cellulose. It known have anti-nemic, anti-fungal and anti- bacterial properties. Application chitosan induces systemic resistance tomato plants against pathogens by increasing phenolic content antioxidant enzymes viz., Polyphenol oxidase...

Recent advancements in the synthesis, properties, and applications of chitosan as second after cellulose available biopolymer nature were discussed this review. A general overview processing production procedures from to Z was highlighted. Chitosan exists three polymorphic forms which differ degree crystallinity (?, ?, ?). Thus, deacetylation, crystallinity, surface area, molecular mass signifi...

The Covid-19 pandemic has increased the need for personal protective equipment (PPE), especially medical personnel: face masks, full clothing, gloves and goggles. To date, they are usually made of thermoplastic polymers, such as polypropylene (PP). reduce risk secondary infections it is essential to enhance antimicrobial (especially antibacterial antiviral) properties materials used in PPE. The...

Despite the shrinkage of water availability worldwide, demand has been climbing due to rapidly increasing human population and impacts numerous hydroclimatic factors. To feed growing meet with exigent need for freshwater, new sources must be identified utilized. In recent years, biopolymer-based hydrogels have explored as a sustainable inexpensive solution capture moisture from humid air supply...

Biopolymers have been employed in many soil applications, such as oil-contaminated soil remediation, due to their environmentally friendly characteristics. This study focused on changes in the wettability and viscosity of polyethylene oxide (PEO) and sodium alginate (SA), according to the variation in concentration and their impact on oil-contaminated soil remediation using biopolymer-decane di...

Cellulose is a biopolymer that has long been used as a biomaterial and its different sources, as Bacterial Cellulose (BC), have shown to possess impressive mechanical properties, which can lead to the development of new biomedical implants. Bacterial Cellulose is a polysaccharide secreted by bacteria as Gluconacetobacter xylinus: BC is composed of highly hydrated nanofibrils and it is character...
