The invention discloses a production method of ultra-low water absorption bamboo wood
fiber decorative plate. (1)
fermentation broth is prepared, specifically, a
bacillus subtilis strain xp is suspended in an LB
liquid medium, and an inoculating loop is used for picking up a bacterial solution and culturing on a slant at 20-40 DEG C for 2-14 h; bacterium obtained are aseptically picked up a singlecolony by the
inoculation loop and the single colony is inoculated into an LB
liquid medium containing 0.1 g / L
malic acid and cultured in a shaking table at 30-38 DEG C until an OD600 value is 2.0, and the
fermentation broth is obtained; (2) raw materials prepared, specifically, the raw materials are all dried to a
moisture content of 8% and comprise, by weight, 50-55 parts of bamboo fibers and 5-8 parts of
pine wood shavings, and the raw materials are uniformly mixed; evenly mixed
raw material plant fibers are uniformly sprayed with the
fermentation broth and turned, and the mixture is fermented at 32-38 DEG C for 8-10h; the amount of spray is that the
fermentation broth is 0.001 time the weight of the
plant fibers; after fermentation,
drying is carried out at the temperature of 60 DEG Cto a
moisture content of 8%, and the
raw material plant fibers are pulverized into
powder for use; (3) molding is performed.
