Natural pigments have been used as color additives in wood since ancient times. The safety, non-toxicity, non-carcinogenicity, and biodegradability of natural pigments have satisfied the increasing pursue of environmental friendliness and health toward people. Thus, microbial pigments will be chosen for industrialization due to their wide distribution, wide variety, fast reproduction speed, and cultivation without time and space restrictions. Two approaches are suitable for applying microbial pigments to the wood dyeing industry. The inoculation is one of the simple and effective ways to dye wood by depositing the pigment secreted by microorganisms on the surface or inside of wood, but the screening and induction of microorganisms is the industrial basis for inoculation dyeing, and requires supporting industrial equipment to complete industrial replicability. Another way is to use the method of extracting pigments secreted by microorganisms for wood dyeing, which is relatively easy to industrialize, but technical issues that need to be addressed include mass production, clean extraction and resoluble solvent of pigments, and deep staining and stability of wood.

接种微生物染色和木材加工中使用的颜料:机遇与挑战

自古以来,天然颜料就一直用作木材中的颜色添加剂。天然色素的安全性,无毒,无致癌性和可生物降解性已经满足了人们对环境友好和健康日益增长的追求。因此,微生物颜料由于其分布广泛,种类繁多,繁殖速度快以及不受时间和空间限制的栽培而将被选择用于工业化。两种方法适用于将微生物颜料应用于木材染色工业。接种是通过将微生物分泌的色素沉积在木材表面或内部来对木材进行染色的一种简单有效的方法,但是微生物的筛选和诱导是接种染色的工业基础,并且需要支持工业设备来完成工业复制。另一种方法是使用提取微生物分泌的颜料的方法进行木材染色,该方法相对较容易工业化,但是需要解决的技术问题包括批量生产,颜料的干净提取和可溶溶剂以及染料的深染和稳定性。木。
