Granulicella mallensis MP5ACTX8(T) is a novel species of the genus Granulicella in subdivision 1of Acidobacteria. G. mallensis is of ecological interest being a member of the dominant soil bacterial community active at low temperatures and nutrient limiting conditions in Arctic alpine tundra. G. mallensis is a cold-adapted acidophile and a versatile heterotroph that hydrolyzes a suite of sugars and complex polysaccharides. Genome analysis revealed metabolic versatility with genes involved in metabolism and transport of carbohydrates. These include gene modules encoding the carbohydrate-active enzyme (CAZyme) family involved in breakdown, utilization and biosynthesis of diverse structural and storage polysaccharides including plant based carbon polymers. The genome of Granulicella mallensis MP5ACTX8(T) consists of a single replicon of 6,237,577 base pairs (bp) with 4,907 protein-coding genes and 53 RNA genes.
马尔伦西粒状菌MP5ACTX8(T)是酸杆菌门第1亚纲粒状菌属的一个新物种。马尔伦西粒状菌具有生态意义,它是北极高山冻原低温和营养限制条件下活跃的优势土壤细菌群落的成员。马尔伦西粒状菌是一种适应寒冷的嗜酸菌和多功能异养菌,能水解一系列糖类和复合多糖。基因组分析揭示了其代谢的多功能性,涉及碳水化合物代谢和转运的基因。这些基因包括编码碳水化合物活性酶(CAZyme)家族的基因模块,该家族参与多种结构和储存多糖(包括植物碳聚合物)的分解、利用和生物合成。马尔伦西粒状菌MP5ACTX8(T)的基因组由一个6,237,577碱基对(bp)的单一复制子组成,有4,907个蛋白质编码基因和53个RNA基因。
