Streptomyces sennicomposti sp. nov., an actinomycete isolated from compost of Senna siamea (Lam.)

Abstract

A member of the genus Streptomyces , designated RCPT1-4T, was isolated from compost of Senna siamea (Lam.), collected from an agricultural area in Rayong province, Thailand. The spore morphology and the presence of ll-diaminopimelic acid in the peptidoglycan indicate that RCPT1-4T shows the typical properties of members of the genus Streptomyces . On the basis of the results of 16S rRNA gene sequence analysis, the strain should be classified as representing a member of the genus Streptomyces and was most closely related to Streptomyces fumigatiscleroticus NBRC 12999T with the highest 16S rRNA gene sequence similarity of 99.2 %, followed by Streptomyces spiralis NBRC 14215T (99.0 %). In addition, RCPT1-4T shared the highest average nucleotide identity by blast (ANIb) (86.0 %), and digital DNA–DNA hybridization (dDDH) (32.1 %) values with S. spiralis NBRC 14215T. Furthermore, several physiological and biochemical differences were observed between RCPT1-4T and the closely related type strains of species with validly published names. These taxonomic data indicated that RCPT1-4T could be considered to represent a novel species of the genus Streptomyces and the name Streptomyces sennicomposti sp. nov. is proposed for this strain. The type strain is RCPT1-4T (=TBRC 11260T=NBRC 114303T).

Marine-Derived Streptomyces sennicomposti GMY01 with Anti-Plasmodial and Anticancer Activities: Genome Analysis, In Vitro Bioassay, Metabolite Profiling, and Molecular Docking

“…The S. sennicomposti RCPT1-4 T derived from the compost of Senna siamea (Lam. ), collected from an agricultural area in Rayong province, Thailand [ 56 ]. The ANI among genes conserved from a pair of genomes was considered a more reliable method than traditional DNA-DNA hybridization [ 40 ].…”

“…Samples for scanning electron microscopy were prepared according to the method of Duangupama et al . 53 . The arrangement of spore was observed under a scanning electron microscope (model JSM-6610 LV; JEOL).…”

Optimization of Thermotolerant Cellulase from Streptomyces sp. M127-1 with Response Surface Methodology using Solid-State Fermentation

“…Bu bozunma kabiliyetinden dolayı, bu bakteri grubunun izolasyon ve karakterizasyonuna sadece kompostlama uygulamaları için değil aynı zamanda kağıt endüstrisi için de özel bir ilgi vardır (Crawford et al 1993, Cuesta et al 2012, Kausar et al 2011. Kompostta bulunan aktinobakterilerin temsilcilerinin bazıları Streptomyces thermovulgaris, Actinobifida chromogena, Thermoactinomyces vulgaris (Insam and de Bertoldi 2007), Micromonospora carbonacea (Kausar et al 2011), Streptomyces lincolnensis, Streptomyces varieustantanus (Cuesta et al 2012) ve Streptomyces sennicomposti (Duangupama et al 2022) örnek verilebilir. Bu çalışmada tanımlama için benzerlik analizi, M127-1 izolatının Streptomyces cinsinin bir üyesi olduğunu ortaya koymuştur.…”
