Abstract
Chitin, the second most abundant biopolymer on earth after cellulose, is composed of β-1,4-N-acetylglucosamine (GlcNAc) units. It is widely distributed in nature, especially as a structural polysaccharide in the cell walls of fungi, the exoskeletons of crustaceans, insects, and nematodes. However, the principal commercial source of chitin is the shells of marine or freshwater invertebrates. Microbial chitinases are largely responsible for chitin breakdown in nature, and they play an important role in the ecosystem's carbon and nitrogen balance. Several microbial chitinases have been characterized and are gaining prominence for their applications in various sectors. The current review focuses on chitinases of microbial origin, their diversity, and their characteristics. The applications of chitinases in several industries such as agriculture, food, the environment, and pharmaceutical sectors are also highlighted.

Abstract
The chitinases are gaining much attention based on their role in the defense against pathogen attacks and harmful insects. The partially chitinase produced by Bacillus licheniformis strain J24 exhibited a large antifungal spectrum, and the highest activity was obtained toward Fusarium species in vitro on PDA and in vivo on corn seeds. The chitinase was inducible by the presence of autoclaved Fusarium conidia in the medium culture and it was active at 70 °C and pH 7 and not affected by the tested chemical agents EDTA and SDS. The nucleotide and amino acid sequences encoding chitinase showed the close phylogenetic relation with chitinase from Bacillus paralicheniformis species. Based on the analysis of the putative domain active, the described chitinase from strain J24 was belonging to the GH family-18 and the novelty of its structure was revealed. Here the combination of functional and structural antifungal extremely chitinase proves its importance in biotechnology area.

Abstract
AIMS To investigate the nutritional requirements of the mycelial growth and pathogenesis-related enzymatic activity on Isaria farinosa and the nutritional effect of fungus on its host Hepialus larvae. METHODS AND RESULTS Sixteen carbon sources, 16 nitrogen sources and 9 vitamin combinations were tested. The nutritional conditions that significantly prevented I. farinosa pathogenesis were selected as feed additives for rearing Hepialus larvae. Citric acid significantly inhibited the growth of I. farinosa and the activity of three enzymes. l-histidine and l-aspartic acid significantly reduced the dry weights of mycelia and their protease and lipase activities. Vitamin combination that lacked VB 1 significantly increased the growth of I. farinosa and enhanced its chitinase and lipase activities. l-aspartic acid, VB 1 or a combination of them were beneficial for maintaining the larvae survival rate and decreasing the disease rate. The result provides new insight to develop a nutrition-based strategy to control fungal epidemics during insect rearing. CONCLUSIONS The ability of some specific nutrients to inhibit mycelial growth and enzymatic activity can prevent epidemics of fungal disease. SIGNIFICANCE AND IMPACT OF THE STUDY These results will aid in the development of nutrition-based strategies to control entomopathogenic fungal epidemics during the large-scale rearing of insects.

Abstract
A novel chitinase gene (RmChi44) from Rhizomucor miehei was cloned and expressed in Escherichia coli as an intracellular soluble and active protein. The recombinant chitinase (RmChi44) was purified to homogeneity and biochemically characterized. The molecular mass of RmChi44 was estimated to be 44.6 kDa on SDS-PAGE. RmChi44 displayed an acidic pH optimum of 4.5 and was stable within pH 4.5-9.0. The optimal temperature of RmChi44 was found to be 50 °C. The Km values of RmChi44 for colloidal chitin and glycol chitin were 4.02 and 1.55 mg/mL, respectively. RmChi44 hydrolyzed colloidal chitin to yield mainly N-acetyl chitobiose, exhibiting an exotype cleavage pattern. Moreover, the enzyme displayed β-N-acetylglucosaminidase activity, splitting N-acetyl COSs with degree of polymerization (DP) 2-5 into their monomer. In addition, RmChi44 showed antifungal activity against some phytopathogenic fungi. This is the first report on an exochitinase showing β-N-acetylglucosaminidase activity and antifungal activity from Rhizomucor species.

Heterologous coexpression of Vitreoscilla hemoglobin and Bacillus megaterium glucanase in Streptomyces lydicus A02 enhanced its production of antifungal metabolites. Enzyme Microb Technol 2015; 81:80-7. [PMID: 26453475 DOI: 10.1016/j.enzmictec.2015.08.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2015] [Revised: 08/03/2015] [Accepted: 08/09/2015] [Indexed: 11/24/2022]
Abstract
Streptomyces lydicus A02 is a novel producer of commercially important polyene macrocyclic antibiotic natamycin and a potential biocontrol agent to several plant fungal diseases, including wilt caused by Fusarium oxysporum f. spp. To improve the natamycin production and the antifungal activity of S. lydicus A02, we coexpressed gene vgb encoding Vitreoscilla hemoglobin (VHb) and bglC encoding Bacillus megaterium L103 glucanase, both under the control of the strong constitutive ermE* promoter, in S. lydicus A02. Our results showed that coexpressing VHb and glucanase improved cell growth, and the engineered strain produced 26.90% more biomass than the wild-type strain after 72h fermentation in YSG medium. In addition, coexpressing genes encoding VHb and glucanase led to increased natamycin production, higher endogenous chitinase activity and exogenous glucanase activity, as well as enhanced antifungal activity in the engineered S. lydicus AVG02 and AGV02, regardless of the position of the two genes on the plasmids. Compared with model strains, few reports have successfully coexpressed VHb and other foreign proteins in industrial strains. Our results illustrated an effective approach for improving antifungal activity in an industrial strain by the rational engineering of combined favorable factors.

Abstract
This paper provides a review of the latest research findings on the applications of microbial chitinases to biological control. Microorganisms producing these enzymes can inhibit the growth of many fungal diseases that pose a serious threat to global crop production. Currently, efforts are being made to discover producers of chitinolytic enzymes. The potential exists that natural biofungicides will replace chemical fungicides or will be used to supplement currently used fungicides, which would reduce the negative impact of chemicals on the environment and support the sustainable development of agriculture and forestry.
