Dechloromonas aquae sp. nov., A Novel Species Isolated from Aquaculture Water of Grass Carp.

A novel bacterial strain, designated Dechloromonas aquae ZY10, was isolated from the aquaculture water of grass carp. The colonies exhibited diameters ranging from approximately 1 to 3 mm and were characterized by a creamy-white coloration, circular shape, smooth texture, translucency, and a convex profile. The cells were facultatively anaerobic and motile, utilizing a single polar flagellum for movement.

Preparation of carboxylate-functionalized cellulose via solvent-free mechanochemistry and its characterization as a biosorbent for removal of Pb2+ from aqueous solution.

Carboxylate-functionalized cellulose can be used as a low cost but effective biosorbent for heavy metals remediation. In this study, it was simply fabricated from wood cellulose and succinic anhydride via solvent-free mechanochemistry in the absence of catalyst at ambient temperature through pan-milling. Fourier transform infrared spectra (FT-IR) confirmed the realization of mechanochemical esterification of cellulose.
