A review on chitin dissolution as preparation for electrospinning application.

Electrospinning has been acknowledged as an efficient technique for the fabrication of continuous nanofibers from polymeric based materials such as polyvinyl alcohol (PVA), cellulose acetate (CA), chitin nanocrystals and others. These nanofibers exhibit chemical and mechanical stability, high porosity, functionality, high surface area and one-dimensional orientation which make it extremely beneficial in industrial application. In recent years, research on chitin - a biopolymer derived from crustacean and fungal cell wall - had gained interest due to its unique structural arrangement, excellent physical and chemical properties, in which make it biodegradable, non-toxic and biocompatible.

Physicochemical properties of fungal chitin nanopaper from shiitake (L. edodes), enoki (F. velutipes) and oyster mushrooms (P. ostreatus).

We evaluate the physiochemical properties of chitin nanopaper derived from three commonly cultivated mushrooms: shiitake (Lentinula edodes), oyster (Pleurotus ostreatus), and enoki (Flammulina velutipes). Mild alkaline extraction of fungal sample yields higher chitin recovery per dry weight (23-35%) compared to crustacean source (9.7%).

Alginate and alginate composites for biomedical applications.

Alginate is an edible heteropolysaccharide that abundantly available in the brown seaweed and the capsule of bacteria such as sp. and sp. Owing to alginate gel forming capability, it is widely used in food, textile and paper industries; and to a lesser extent in biomedical applications as biomaterial to promote wound healing and tissue regeneration.

Surface properties of chitin-glucan nanopapers from Agaricus bisporus.

The structural component of fungal cell walls comprises of chitin covalently bonded to glucan; this constitutes a native composite material (chitin-glucan, CG) combining the strength of chitin and the toughness of glucan. It has a native nano-fibrous structure in contrast to nanocellulose, for which further nanofibrillation is required. Nanopapers can be manufactured from fungal chitin nanofibrils (FChNFs).

Utilization of sludge palm oil as a novel substrate for biosurfactant production.

This paper introduces sludge palm oil (SPO) as a novel substrate for biosurfactant production by liquid state fermentation. Potential strains of microorganism were isolated from various hydrocarbon-based sources at palm oil mill and screened for biosurfactant production with the help of drop collapse method and surface tension activity. Out of 22 isolates of microorganism, the strain S02 showed the highest bacterial growth with a surface tension of 36.
