TL;DR: In this article, the fibrillated chitin samples were observed by FE-SEM and were found to have a fine nanofiber network; the structure was highly uniform with a width of 10-20nm and a high aspect ratio.

TL;DR: Chitinase enzyme has received increased attention due to its wide range of biotechnological applications, especially in agriculture for biocontrol of phytopathogenic fungi and harmful insects, and out of metal ions Mn 2+ and Cu 2+ enhanced enzyme production in the case of HS6, however, Co 2+ was the most appropriate for HS4.

TL;DR: Enzyme activity was correlated with the soil fungal population but not with numbers of actinomycetes or bacteria, and a specialized mycoflora was associated with chitin decomposition.
Abstract: Chitinase activity was determined by incubating a mixture of toluene-treated soil with 1% (w/w) colloidal chitin suspension for 18 h at 37°C and then, after dilution, assaying the amount of N-acetyl-glucosamine released. Maximal chitinase activity was observed at 45°C and optimal pH for enzymatic reaction was 5.0–5.5. Soil chitinase activity decreased with increasing soil depth and was significantly affected by crop cover and fertilization regime. Chitin added to soil stimulated chitinase activity. Enzyme activity was correlated with the soil fungal population but not with numbers of actinomycetes or bacteria. A specialized mycoflora was associated with chitin decomposition.

TL;DR: The biomedical applications and biological properties of chitin/chitosan-based nanofibrous scaffolds in bone tissue engineering are outlined and found structurally similar to bone's extracellular matrix and can assist in bone regeneration.
