科研工作简介

我们聚焦于细菌硫代谢和合成生物学创新,在两个方向的研究都取得了不错成绩。具体学术创新与贡献如下:

1.自养细菌一直被认为是环境硫循环的主要贡献者,但异养代谢细菌在硫循环中的贡献一直未被阐明。我们以异养细菌为对象,首次揭示了其存在多条活跃的硫氧化途径,并对涉及途径中的酶在分类、生理与生化层面提出新认知,创新性提出异养细菌的硫代谢是环境硫元素生物地球化学循环不可或缺的一环。硫烷是细菌硫氧化的关键中间产物,并且硫烷在哺乳动物细胞中的代谢与调控受到了广泛关注,但其在原核细胞中的代谢与功能研究一直是空白。我们首次关注到细菌中硫烷的生理代谢与调控功能。提出了硫烷检测新方法,分析了不同细菌中硫烷分子的含量、代谢途径和代谢稳态特征,并证实了硫烷参与了对铜绿假单胞菌的细菌抗逆、耐药和群体效应等重要生理功能的调控机制。

2.在合成生物学工作中:a)众所周知,DNA克隆和感受态细胞制备与转化是大多数生物学实验室的常规必备技术,我们对这些经典技术进行了系统创新:建立了新的DNA克隆和感受态细胞制备方法:建立的DNA克隆方法,其效率已赶超主流商业化试剂盒的水平,但成本仅合5分钱/反应,是最廉价的DNA克隆方法;成功将化学法制备的大肠杆菌感受态细胞的效价优化到目前已报道的最高水平,制备感受态使用的克隆型菌株也被证实具有最快的生长速率。进一步阐明大肠杆菌DNA短同源重组的新分子机制,为进一步开发更简便克隆方法奠定了基础。b)在中国,痛风是仅次于糖尿病的第二大常见的代谢性疾病,但常见药存在集中度高,副作用强的缺陷。我们提出了可借助优化工程益生菌的尿酸降解能力来治疗痛风的新疗法。工程菌降解尿酸需要氧气参与,但肠道中氧气受限,我们的工作解决了这项缺陷,实现了低氧条件下尿酸的快速降解,进一步借助肠道灌胃和血液注射证实:该菌剂可在1小时内快速缓解高尿酸血症小鼠的血尿酸水平。

5年来,本人已发表署名通讯作者或者第一作者的SCI论文共26篇,专著章节1篇。其中一区5篇,影响因子大于10的有4篇,Nature Index期刊2篇。发表在以ISME J, Nucleic Acids Research,Gut Microbes,Redox Biology,STOTEN,Analytical Chemistry等为代表的主流专业期刊上,2篇年均引用超过10,其中1篇年均引用已超25。共承担国家级科研项目4项,合计到账科研经费近170万。工作受到了业内专家的肯定,相继破格晋升为bet365 코리아教授,荣获bet365 코리아校内齐鲁青年学者称号,入选山东省高层次人才。
