Preparation and application of special mildew preventing agent for bamboo wood and bamboo products

Abstract

The invention relates to a preparation and an application of a special mildew preventing agent for bamboo wood and bamboo products. The preparation process comprises the following steps of: using a slant culture medium to activate and culture a lysobacter enzymogenes C3 bacterial strain; transferring the bacterial strain to seed culture liquid; carrying out culturing for 48h at 24-30 DEG C and 230rpm; transferring the bacterial strain to fermentation culture liquid in 10% proportion; and culturing to obtain the mildew preventing agent. The mildew preventing agent can resist a heat treatment for 1h at 70 DEG C or can be stored for more than 180 days without a remarkable activity influence; after the mildew preventing agent treats the bamboo wood in three methods, namely soaking (for more than 4h), uniformly spraying or daubing, a mildew preventing effect is very remarkable; the bamboo wood keeps an original color andperformance. The invention provides a high-efficient biological mildew preventing agent and the application of mildew prevention of the bamboo wood; production cost is low; the conventional microbial fermentation equipment and a technology can be utilized for mass production; and source is very convenient. Mildew-preventing and preservative effects of the bamboo wood is very remarkable by different treatment methods, therefore, the mildew preventing agent has a wide application prospect in preventing mildew and corrosion of the bamboo products.

Description

technical field

[0001] The invention relates to the technical field of biological mildew prevention, in particular to the preparation and application of a special microbial anti-mold agent for bamboo and bamboo products. Background technique

[0002] my country is a country that is short of forest resources, and it is an urgent task to find new wood substitute resources. The chemical composition of bamboo is similar to that of wood, mainly composed of cellulose, hemicellulose and lignin, which can replace wood. Moreover, my country's bamboo resources are also very rich, with a total of 39 genera and more than 500 species. Bamboo also has the advantages of rapid growth, high yield, early maturity, and wide application. Expanding the development and utilization of bamboo is of great significance to local economic development and ecological construction. However, bamboo contains more starch, polysaccharides and water-soluble nutrients than wood. Among them, the protein conte...
