The present invention relates to a multifunctional wood preservative composition containing a compound prepared by reaction of hydrazine hydrate and boric acid and to a method for wood preservation treatment using the same.

The wood preservative composition of the present invention can not only impart flame retardant, insect-repellent, rot-resistant, insect-repellent, and rust-proof effects to wood, such as various wooden structures including wooden cultural assets, but also causes no whitening and makes relatively fewer color changes for dancheong. Furthermore, the wood preservative composition of the present invention is provided as a one-component type liquid and thus can save time and costs for wood treatment and is convenient to use.

This invention relates generally to methods of preparing compositions from microorganisms such as cyanobacteria, particularly to preparing compositions with antifungal and/or antibacterial characteristics, and more particularly to preparing cyanobacteria or other microorganism-derived compositions for use in construction materials. Cyanobacteria make various kinds of natural products that may be useful for a variety of applications, including products with antifungal and/or antibacterial activity, and other biologically active compounds (e.g. immunomodulatory, antitumor, antithrombotic, anticoagulant, anti-mutagenic, anti-inflammatory, antimicrobial, and antiviral). Some of the especially useful ones might be antifungals and antibacterials, such as by incorporation or application onto construction materials (e.g. drywall).
