Bacillus bacteria are advantageous antagonistic organisms that can be used as bio-control agents. This study is aimed at screening the activity of different strains isolated and molecular identification superior chitinase producer strain against dermatophytes fungi. Soil samples were collected from places Kotoor city, Gharbia Governorate, Egypt Al Madina Munawwarah, Kingdom Saudi Arabia. A coll...

Seaweed surfaces harbor diverse epibiotic bacterial communities with functions related to morphogenesis, host health, and defense. Among seaweed holobionts, culturable strains can represent innovative sources of bioactive compounds enzymes. The global industrial demand for microbial enzymes is continually growing in order improve certain manufacturing processes new perspectives exploitation. In...

ABSTRACT The role of chitinase production by Stenotrophomonas maltophilia strain C3 in biological control of leaf spot on tall fescue (Festuca arundinacea), caused by Bipolaris sorokiniana, was investigated in vitro and in vivo. The filtrate of a broth culture of C3, with chitin as the carbon source, was separated into fractions. A high molecular-weight fraction (>8 kDa) was chitinolytic and mo...

Understanding gene flow in genetically modified (GM) crops is critical to answering questions regarding risk-assessment and the coexistence of GM and non-GM crops. In two field experiments, we tested whether rates of cross-pollination differed between GM and non-GM lines of the predominantly self-pollinating wheat Triticum aestivum. In the first experiment, outcrossing was studied within the fi...

To investigate the diagnostic value of chitinase-3-like protein 1 and keratin 5 in bronchoalveolar lavage fluid 88 patients with lung disease. This was a case control study to collect 50 cancer (malignant disease group) 38 benign (benign who were admitted respiratory medicine department affiliated hospital medical school Ningbo university from December 2019 March 2020. The enzyme-linked immunos...

We describe the cloning, overexpression, purification, characterization and crystal structure of chitinase G, a single-domain family 19 chitinase from the Gram-positive bacterium Streptomyces coelicolor A3(2). Although chitinase G was not capable of releasing 4-methylumbelliferyl from artificial chitooligosaccharide substrates, it was capable of degrading longer chitooligosaccharides at rates s...

Confocal immunofluorescence microscopy was used to demonstrate that the Autographa californica nucleopolyhedrovirus (AcMNPV) chitinase was localized within the endoplasmic reticulum (ER) of virus-infected insect cells. This was consistent with removal of the signal peptide from the chitinase and an ER localization motif (KDEL) at the carboxyl end of the protein. Chitinase release from cells, a ...
