The 19th Heads of State and Government Summit of the Group of 20 (G20) will take place in November 2024 in Rio de Janeiro, marking Brazil's first term as the G20 rotating presidency as South America’s largest economy.

Ana Cristina Carvalho, Chair of the Tourism Association at Federation Chambers of Foreign Trade (FCCE) of Brazil, shared in an interview with China News Network that this year, which marks the 50th anniversary of Brazil-China diplomatic ties, has seen significant progress in bilateral relations. In particular, enhanced diplomatic relations have made travel between the two countries more accessible.

Ana further noted that this year’s G20 in Rio offers a comprehensive platform for participants to discuss topics such as health, education, and urban quality of life. Brazil looks forward to proposing and adopting initiatives at the G20, which will contribute to global development. (Hao Yunhui, Zhao Li)

这项微生物领域重要研究成果论文,近日已在施普林格·自然旗下专业学术期刊《通讯—生物学》(Communications Biology)发表。科研团队通过该成果方法的实践运用,证实微生物菌株在复杂工业化场景中的发酵性能显著增强,也为生物制造、微生物新菌种资源等方面的进一步研究提供有力支撑,具有良好的应用前景。

酵母脂质合成的关键因素之一是乙酰辅酶A,这一重要前体充当着脂质分子的“原材料”,是脂质合成必不可少的物质。不过,传统的代谢途径限制了乙酰辅酶A的有效供应和脂质的积累射雕英雄传83版国语,这让脂质的产量不够高。在本项研究中,为增加脂质合成量,科研团队利用重离子辐射和基因编辑等相关技术优化酵母代谢途径,提高乙酰辅酶A的供应效率,使酵母能够生产更多的脂质。

研究过程中,科研团队利用大科学装置——兰州重离子加速器对酵母进行重离子辐射处理,结合多组学方法识别并验证了与脂质代谢相关的关键基因ALD4。随后,他们通过基因编辑技术上调ALD4核心代谢中间产物的代谢通量,有效增加脂质合成所需前体乙酰辅酶A的供应射雕英雄传83版国语,使乙酰辅酶A水平较之前提高17.10%,从而显著提高酵母在合成脂类和其他高附加值化合物方面的产量。(完)
