由林强博士，李玲娟博士，李香真研究员等研究人员共同完成的研究工作 “微生物群落的功能保存决定了厌氧消化的组成可预测性”，发表在国际主流期刊The ISME Journal (2023) 。该研究工作主要关注微生物研究领域的重点、难点问题，即微生物群落结构及其变化的可预测性。特别是在微生物主导的生态系统中，比如厌氧发酵系统，微生物对生态系统的功能和服务起到至关重要的作用。那么生态系统的功能是否可预测...
中国科学院植物研究所研究人员揭示多年冻土区土壤微生物养分限制特征（图）
中国科学院 植物研究所 冻土区 土壤微生物
2023/9/19
中国科学院植物研究所杨元合研究组以青藏高原多年冻土区为研究对象，基于大尺度野外取样，通过多种研究手段，包括胞外酶化学计量、元素阈值比、功能基因丰度和养分添加实验，揭示了冻土区土壤微生物养分限制特征。研究人员基于4种方法得到的结果一致显示，冻土区土壤微生物受氮磷共同限制。并且，与冻土层相比，活动层土壤微生物养分限制程度更强。进一步研究发现，土壤资源化学计量和真菌细菌比是微生物养分限制空间变异的主要驱...

国际最新研究揭示海底微生物存活的代谢秘诀
海底微生物 代谢
2022/1/28
施普林格·自然旗下学术期刊《自然-通讯》最新发表一篇微生物学研究论文显示，较高的能量代谢率或使一个微生物种群能够生活在海床下1000多米深、温度最高有120°C的沉积物中。这项研究结果或有助于阐释生物在被认为生命可承受的最高温度下的生存策略。
根据发表在美国微生物学会期刊《应用与环境微生物学》（Applied and Environmental Microbiology）上的一项研究成果，加拿大北极寒冷水域中的海洋细菌能够生物降解石油和柴油燃料。论文的共同作者、加拿大卡尔加里大学地球微生物学副教授Casey Hubert博士提到，基因组测序揭示了包括Paraperlucidibaca、Cycloclasticus和Zhongshania...
