In the context of achieving the “2060 carbon neutrality” goal, biodiesel has been recognized as an important, clean, and renewable energy fuel. The lipid produced by oleaginous yeast can account for up to 70% of the dry cell weight and is considered an ideal substitute for converting vegetable oil into biodiesel (Vasconcelos et al. in Appl Microbiol Biotechnol 103:3651–3667, 2019 [1]). In the previous chapters discussing the utilization of different oleaginous microorganisms to accumulate and generate biodiesel raw material oils, it frequently mentioned the use of lignocellulosic biomass can serve as an alternative carbon source for glucose to reduce carbon source costs. This is because lignocellulosic biomass is one of the most widely distributed and abundant biomass resources worldwide. It is estimated that the global annual production of lignocellulosic biomass is approximately 181.5 billion tons (Dahmen et al. in Glob Change Biol Bioenergy 11:107–117, 2018 [2]). Common lignocellulosic materials include agricultural waste (e.g., sugarcane bagasse, rice straw, wheat straw, soybeans, oats, grains), tree stumps, sawdust, plants, branches, and some urban solid waste. The secondary cell wall of plants contains 40–80% cellulose, 10–40% hemicellulose, and 5–25% lignin.

摘要

In the context of achieving the “2060 carbon neutrality” goal, biodiesel has been recognized as an important, clean, and renewable energy fuel. The lipid produced by oleaginous yeast can account for up to 70% of the dry cell weight and is considered an ideal substitute for converting vegetable oil into biodiesel (Vasconcelos et al. in Appl Microbiol Biotechnol 103:3651–3667, 2019 [1]). In the previous chapters discussing the utilization of different oleaginous microorganisms to accumulate and generate biodiesel raw material oils, it frequently mentioned the use of lignocellulosic biomass can serve as an alternative carbon source for glucose to reduce carbon source costs. This is because lignocellulosic biomass is one of the most widely distributed and abundant biomass resources worldwide. It is estimated that the global annual production of lignocellulosic biomass is approximately 181.5 billion tons (Dahmen et al. in Glob Change Biol Bioenergy 11:107–117, 2018 [2]). Common lignocellulosic materials include agricultural waste (e.g., sugarcane bagasse, rice straw, wheat straw, soybeans, oats, grains), tree stumps, sawdust, plants, branches, and some urban solid waste. The secondary cell wall of plants contains 40–80% cellulose, 10–40% hemicellulose, and 5–25% lignin.
