TL;DR: In this article, a Box-Behnken design with three variables and three levels was applied in order to approach the prediction of optimal enzyme/substrate ratio, temperature and incubation time on the deproteinization degree with Bacillus mojavensis A21 crude protease.

TL;DR: In this article, a study was undertaken to extract chitin and chitosan by chemical method, and several treatments with acid and alkali were taken into consideration to determine effective concentration for yielding optimum output.

TL;DR: Data is reviewed which partially explains the paradoxical action of chitosan which at similar concentrations can completely inhibit all RNA synthesis in some fungal organisms and thus suppress gene activity.
Abstract: The regulatory role of chitosan in eucaryotic organisms may have far reaching consequences because chitosan and its acetylated form, chitin, are prevalent in nature. We have found two different regulatory functions for chitosan in a simple fungal-plant interaction1. Chitosan which is a normal component of the cell walls of some fungi (Fig. 1) can activate specific genes in plants and at similar concentrations can completely inhibit all RNA synthesis in some fungal organisms and thus suppress gene activity. In this paper we review data which partially explains this paradoxical action.

TL;DR: The chemical modification of chitin and chitosan by phosphorylation is expected to be biocompatible and is able to promote tissue regeneration and be able to bring new or improved properties.

TL;DR: This finding, together with the apparent zymogenic nature of Chs2, is consistent with the hypothesis, previously put forward for Chs1, that localized deposition of chitin is attained by activation of the zymogen form at a specific time and place.
