Abstract
Termites present a significant hazard to wooden structures, agriculture and urban environments. Termiticides are now required to meet more stringent environmental standards. Microbial metabolites with antitermitic properties are considered practical alternatives for termite control. Here, we report an antitermitic compound-producing endophytic bacterium HDZK-BYB36 isolated from the termite-resistant tree, Port-Orford-cedar (Chamaecyparis lawsoniana). The morphological, physio-biochemical, and 16S rDNA characteristics of the bacterium were investigated, as well as its antimicrobial and antitermitic activities. The antitermitic compounds from the strain HDZK-BYB36 were analyzed by GC-MS. Phylogenetic analyses revealed that HDZK-BYB36 was a subspecies of Paenibacillus aliginolyticus, sharing 98.72% identity with P. alginolyticus DSM 5050T. The HDZK-BYB36 demonstrated robust antimicrobial and termiticidal activities. It produced at least 4 antitermitic compounds, namely nootkatone, τ-muurolol, torreyol and α-cadinol, as determined by GC-MS analysis. The isolation of HDZK-BYB36 presents an effective and innovative resource for generating antitermitic compounds, providing a sustainable approach towards the prevention and control of termites.
期刊介绍:
Applied Biochemistry and Microbiology is an international peer reviewed journal that publishes original articles on biochemistry and microbiology that have or may have practical applications. The studies include: enzymes and mechanisms of enzymatic reactions, biosynthesis of low and high molecular physiologically active compounds; the studies of their structure and properties; biogenesis and pathways of their regulation; metabolism of producers of biologically active compounds, biocatalysis in organic synthesis, applied genetics of microorganisms, applied enzymology; protein and metabolic engineering, biochemical bases of phytoimmunity, applied aspects of biochemical and immunochemical analysis; biodegradation of xenobiotics; biosensors; biomedical research (without clinical studies). Along with experimental works, the journal publishes descriptions of novel research techniques and reviews on selected topics.
