Background

The branch handicraft is a wood product, is a biological material, contains rich cellulose, is a complex polysaccharide, provides nutrients for wood decay fungi and mould fungi under certain temperature and humidity environment, and is extremely easy to be damaged by fungi and ants, thereby changing the appearance and reducing the strength. The existing method for improving the corrosion resistance of the preservative is mainly to spray the preservative on the surface of the preservative, and the preservative is mostly a chemical reagent, not only has pungent smell, but also causes certain environmental pollution. In addition, if the preservative is directly sprayed on the surface of the branch artware, the preservative effect is only temporary and is not obvious. Therefore, the development and research of a special anticorrosion treatment process for the branch artware with durable anticorrosion property are urgently needed.

Nisin: produced by the prokaryote streptococcus lactis which stimulates metabolism, belongs to one of bacteriocins, has wide antibacterial spectrum, and is a biodegradable non-toxic natural preservative. Early studies show that the compound can effectively inhibit the growth and the propagation of most gram-positive bacteria of food spoilage, clostridium botulinum, staphylococcus aureus, streptococcus hemolyticus, heat-resistant spoilage bacteria and other microorganisms. The antibacterial principle is as follows: after the addition of the "adsorption binding partner" by nonspecific (positive and negative charge effects) on the cell membrane of gram-negative bacteria microorganisms, the membrane structure is invaded and destroyed to form a multi-permeable pore channel, the intracellular osmotic pressure is changed, and the cells are inactivated by autolysis.

Natamycin: is a microbial food preservative separated from streptomyces nattararii, streptomyces chattanoagatus, streptomyces fuscopsis and the like in actinomycetes after biological fermentation. Can inhibit fungi, yeasts, certain protozoa and certain algae, but has no inhibition effect on bacteria and viruses, the natamycin is non-toxic and has good chemical stability, is insoluble in water and grease, most of the natamycin taken into a human body can be discharged along with excrement, and cannot be enriched in the human body. The principle of gas mould proofing is as follows: natamycin (lactone ring structure) can react with sterol compounds on fungal cell membranes, thereby triggering structural changes of the cell membrane to rupture, leading to leakage of cell contents and eventual death by inactivation, but natamycin cannot inhibit the growth of putrefying bacteria.

Lysozyme: is a hydrolase composed of polypeptide chains and acts exclusively on the cell wall of microorganisms. Lysozyme has inhibitory effects on gram-positive bacteria, fungi and viruses, but has little effect on gram-negative bacteria. The bacteriostatic principle is as follows: lysozyme can hydrolyze and break beta-1, 4 glycosidic bonds formed between N-acetylmuramic acid on peptidoglycan of cell wall and N-acetylglucosamine acetate through active centers in the spatial structure of protein, so that cell wall is damaged, cell contents leak out, and finally cell autolysis death is caused.

The microbial preservative has natural and non-toxic characteristics, and can not cause environmental pollution when being used for preserving the branch artware, but has a single bacteriostatic range and needs to be used together with other preservatives.
