Kribbella sindirgiensis sp. nov. isolated from soil

Abstract

A Kribbella strain FSN23 was isolated from soil sample which was collected from Caygoren Dam lakeside located in Sındırgı, Turkey. The isolate was investigated using a polyphasic approach consisting of numeric, chemotaxonomic and molecular analysis. The isolate indicated chemotaxonomic, morphological and phylogenetic properties associated with members of the genus Kribbella. Phylogenetic analysis based on the 16S rRNA sequence of the strain demonstrated that the strain forms a subclade with K. aluminosa HKI 0478 and K. jejuensis HD9. The organism formed an extensively branched substrate and aerial hyphae which generated spiral chains of spores with smooth surfaces. The cell wall contained LL-diaminopimelic acid, and the whole cell sugars were glucose and ribose along with trace amounts of mannose. The polar lipids were identified as phosphatidylglycerol, diphosphatidylglycerol, four unidentified lipids and five unidentified polar lipids. The predominant menaquinone was MK-9(H). The major cellular fatty acids were anteiso-C and iso-C. Polyphasic taxonomy properties confirm that strain FSN23 represents a novel Kribbella taxon distinguished from closely related type strains. Hence, strain FSN23 (=KCTC 29220 = DSM 27082) is proposed as the type strain of a novel species with the name Kribbella sindirgiensis sp. nov.

Effect of Organic and Conventional Systems Used to Grow Pecan Trees on Diversity of Soil Microbiota

“…The Actinobacteria phylum has diverse physiological properties, such as the production of extracellular enzymes for the decomposition of organic matter [75]. It has also been shown that Actinobacteria abundance is associated with the respiration rates of the soil [76,77], which agrees with the current study, since CO 2 emission was greater under Conv management. Regarding bacterial genera that were more abundant in soil under Org management, Gemmata is capable of using glucose and galactose as a source of carbon in order to thrive, and therefore it is an important producer in the carbon and N cycles [78,79].…”

Soil Rehabilitation Promotes Resilient Microbiome with Enriched Keystone Taxa than Agricultural Infestation in Barren Soils on the Loess Plateau

“…However, the genus Flavisolibacter has previously been reported in cultivated soils [ 99 ]. The genera Aeromicrobium and Kribbella (belonging to the Actinobacteria) have also been isolated from alkaline soils [ 100 , 101 ] similar to Loess alkaline agricultural soils. The specific functions of these keystone taxa still remain largely unknown.…”

Effects of Different Types of Additional Fertilizers on Root-associated Microbes of Napa Cabbage Grown in an Andosol Field in Japan

“…Kribbella and Niastella (corresponding to ASV-B3 in Table S3 ) have been identified as a nitrate reducer and denitrifier, respectively ( Nishizawa et al , 2014 ; Ozdemir-Kocak et al , 2017 ). Increases in the abundance and activities of these bacteria in a rhizosphere are not favorable from the viewpoint of agriculture because their effects on mineral nitrogen may reduce the efficiency of nitrogen fertilization.…”
