The chemical ecology of rotifers has been little studied. A yet unknown property is presented within some monogonant rotifers, namely the ability to produce an exogenic filamentous biopolymer, named ‘Rotimer’. This rotifer-specific viscoelastic fiber was observed in six different freshwater monogonants (Euchlanis dilatata, Lecane bulla, Lepadella patella, Itura aurita, Colurella adriatica and T...

Bioplastics have emerged as a promising alternative to conventional plastics, marketed environmentally friendly and sustainable materials. They provide variety of methods for efficient waste management contributing the goals circular economy. At their end-of-life stage, bioplastics can generate added value through aerobic anaerobic biological treatments (composting or digestion). In this study,...

Cellulose nanocrystals (CNC) were prepared by formic acid hydrolysis and TEMPO- (2,2,6,6-tetramethyl-piperidine-1-oxyl-) mediated oxidation. The CNCs reinforced into biopolymers chitosan (CHI), alginate (ALG), gelatin (GEL) to obtain “CNC-ALG-GEL” “CNC-CHI-GEL” hydrogels. synthesized hydrogels characterized for physicochemical, thermal, structural characterization using Fourier transform infrar...

This examination explains the utilization of bio-polymer powder for clayey soil enhancement. The article concentrates around examining strength attitude soils built up with homogenous bio-polymer. Carboxy methyl cellulose was determined as material to build normal soft soil. biopolymer has been added two separated rates (0.5 and 3%) by total weight Different tests were carried out consider impa...

Using a path integral technique, we show exactly that for a semiflexible biopolymer in constant extension ensemble, no matter how long the polymer and how large the external force, the effects of short-range correlations in the sequence-dependent spontaneous curvatures and torsions can be incorporated into a model with well-defined mean spontaneous curvature and torsion as well as a renormalize...

The wastes generated by the shrimp industry are approximately between 50 and 60% of catch volume. These residues such as head, viscera, shell potential pollutants if they not treated for proper disposal. One way to solve this problem is use functional food ingredients. In regard, rich in chitin, second most abundant biopolymer on planet after cellulose. Chitin composed N-acetyl glucosamine, a m...

Bacterial cellulose (BC) is a unique biopolymer synthesised by many bacteria as critical element of their biofilm matrix. The most known and efficient producers BC are from the genus Komagataeibacter. cellulose, with its properties, high crystallinity, mechanical strength, unprecedented ability to hold water, an object interest in industries. Despite enormous efforts that have been made develop...

the high hydrophilic property of biopolymer based plastics is one of the most important defects of them. blending biopolymers with compatible synthetic polymers and using nano particles such as nanoclay as nanofiller are improving methods that have been extensively considered in recent years. carboxymethyl cellulose (cmc) is one of the lowest cost biopolymers that have enormous applications in ...
