| Abstract |
During an investigation exploring potential sources of novel thermophilic species and natural products, a novel thermophilic and alkaliphilic actinomycete with alkaline cellulase producing ability, designated strain 4-2-13(T), was isolated from soil of a tropical rainforest in Xishuangbanna, Yunnan province, China. The morphological and chemotaxonomic characteristics of strain 4-2-13(T) are consistent with those of the members of the genus Streptomyces. The strain forms extensively branched aerial mycelia and substrate mycelia. Spiral spore chains were observed on aerial mycelia; spores were oval to cylindrical, with smooth surfaces. The organism was found to contain LL-diaminopimelic acid as the diagnostic diamino acid in the cell wall peptidoglycan. The whole cell hydrolysates were found to contain glucose and ribose. The cellular fatty acid profile mainly consists of anteiso-C17:0 and iso-C16:0. The menaquinones were identified as MK-9(H8), MK-10(H6) and MK-9(H6). The polar lipids profile were found to consist of diphosphatidylglycerol, phosphatidylmethylethanolamine, a ninhydrin-positive glycophospholipid, phosphatidylinositol, phosphatidylglycerol and unidentified glycolipids. The 16S rRNA gene sequence analysis showed that the organism belongs to the genus Streptomyces and in the 16S rRNA gene tree it formed a distinct phyletic line together with the closely related type strain Streptomyces burgazadensis Z1R7(T) (95.2% sequence similarity). However, the phenotypic characteristics of strain 4-2-13(T) are significantly different from those of S. burgazadensis Z1R7(T). Based on the phenotypic, chemotaxonomic and phylogenetic characteristics, strain 4-2-13(T) represents a novel species in the genus Streptomyces, for which the name Streptomyces thermoalkaliphilus sp. nov. is proposed. The type strain is 4-2-13(T) (= DSM 42159(T) = CGMCC 4. 7205(T)). |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 08 November 2017.
All research outputs
#20,451,991
of 23,007,887 outputs
Outputs from Antonie van Leeuwenhoek
#1,750
of 2,036 outputs
Outputs of similar age
#288,849
of 331,365 outputs
Outputs of similar age from Antonie van Leeuwenhoek
#31
of 38 outputs
Altmetric has tracked 23,007,887 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,036 research outputs from this source. They receive a mean Attention Score of 3.6. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 331,365 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 38 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
