Method for dyeing bamboo wood with biological pigment

The invention discloses a method for dyeing bamboo wood by regulating and controlling the growth and pigment secretion of color-changing fungi. The method comprises the following steps: 1) culturing discoloring fungi into a dying fungus solution; 2) soaking the bamboo wood in the dyeing fungus solution for inoculation; 3) controlling the growth speed and pigment secretion of the color-changing fungi on different surfaces of the bamboo wood; 4) sterilizing the dyed bamboo wood; and 5) conducting maintaining and balancing to obtain the novel biological pigment dyed bamboo wood. According to themethod for dyeing the bamboo wood with biological pigment, the excellent biocompatibility and anti-oxidation biological characteristics of the color-changing fungi on the bamboo wood are utilized, andthe method has the advantages of environment friendliness and the like, can be applied to dyeing of bamboo wood unit products and has wide development prospects. 本发明公开了一种通过调控变色菌生长与色素分泌来染色竹木材的方法。工艺步骤包括1)将变色真菌培养成染色真菌溶液；2)竹木材浸泡于
