Application of lignin in the petroleum industry
②
Petroleum industry.
Petroleum has a close relationship with lignin; they have
many similar structural units and linked bonds. Therefore, the white-rot fungi are
applied in oil biotransformation and biological processing, with advantages of
cleanliness and efficiency, which is a promising research direction. Many of the
existing oil industry products can take advantage of lignin for production, as shown
in Fig.

.
③
Pharmaceutical industry
Lignin as a raw material can be produced by a variety of pharmaceutical prepara-
tions, which has great significance for the rapid development of the pharmaceutical
industry today. Application of lignin in the pharmaceutical industry is shown in
Fig.

shows that the lignin molecular structure contains a variety of active
groups, and the lignin can be slowly degraded by microorganisms in the soil,
converting it to humus, leading to the inhibition to soil urease activity and the
promotion of plant growth and soil improvement [
