天津工生物所吴信团队在木质素生物合成微生物油脂和蛋白方面取得新突破
Core Viewpoint - The research team at the Tianjin Institute of Industrial Biotechnology has made significant advancements in the bioconversion of lignin into microbial oils and proteins, addressing the challenges of lignin degradation and high-value utilization [5][7]. Summary by Sections Research Breakthroughs - The team successfully developed a genetically engineered strain, Curvularia clavata M6, which efficiently degrades lignin and simultaneously synthesizes oils and proteins. This was achieved by combining genome editing technology with high-throughput screening methods [5][6]. - The engineered strain M6 exhibited a 75% increase in laccase activity, reaching 228.58 U/L, and achieved an oil accumulation of 49% of the cell dry weight while maintaining a stable protein content of 33% [6]. Industrial Application Potential - In a 5-liter fermentation scale-up, the laccase activity further increased to 240.43 U/L, with oil content rising to 51%, indicating strong stability and potential for industrial applications [6][7]. - The research highlights the effective conversion of lignin into valuable microbial oils and proteins, providing a feasible pathway for high-value utilization of lignin resources [7][9]. Future Directions - The research is supported by national strategic technology initiatives, and the team has filed for two patents related to their findings. They will present their latest research at the upcoming NFUCon 2025 forum, focusing on biomass utilization strategies [8][9].

Core Viewpoint - The Ministry of Agriculture and Rural Affairs, along with ten other departments, has introduced a plan to promote agricultural product consumption, focusing on optimizing supply, innovating circulation, and activating the market through 23 specific measures to adapt to new consumer trends and preferences [1]. Group 1: Nutritional and Health Consumption - There is a shift in consumer demand from "sufficient food" to "nutritious and healthy food," prompting the Ministry to advocate for increased consumption of soybeans and milk to help consumers form a scientific dietary structure [1][2]. - Current data indicates that the average per capita milk consumption in China is 40.5 kg, significantly below the recommended dietary intake of 110-183 kg, and lower than the 80-90 kg levels in Japan and South Korea [2]. - Soybean and soybean product consumption is also below the recommended levels by 59%, indicating substantial growth potential in these areas [2]. Group 2: Public Health and Nutrition Education - The Ministry plans to enhance public services related to nutrition and health by developing and promoting healthy dietary plans, particularly targeting student groups to optimize nutrition in school meals [3]. - There will be a focus on promoting healthy eating habits through campaigns that encourage reduced oil intake, increased consumption of soy and milk, and greater intake of fruits, vegetables, and whole grains [3]. - The Ministry will also create food maps for dairy and beef to integrate agricultural product consumption with cultural and tourism activities [3]. Group 3: Food Industry Upgrading - The Ministry of Industry and Information Technology emphasizes the need to establish a diversified food supply system and enhance the quality of the food industry to drive agricultural product consumption [4]. - The application of biotechnology in the food industry is being promoted to expand agricultural development, including the optimization of production processes for various food products [5]. - The Ministry is also focusing on developing local specialty food industries and promoting deep processing of food products to enhance agricultural product consumption quality [6].
