Streptomyces pluripotens sp. nov., a bacteriocin-producing streptomycete that inhibits meticillin-resistant Staphylococcus aureus

Abstract

and it showed a range of phylogenetic and chemotaxonomic properties consistent with those of the genus Streptomyces. The diamino acid of the cell-wall peptidoglycan was LL-diaminopimelic acid. The predominant menaquinones were MK-9(H 6 ), MK-9(H 4 ) and MK-9(H 8 ). Polar lipids detected were a lipid, an aminolipid, a phospholipid, phosphatidylinositol, phosphatidylethanolamine and two glycolipids. The predominant cellular fatty acids (.10.0 %) were anteiso-C 15 : 0 (20.8 %), iso-C 16 : 0 (18.0 %), iso-C 15 : 0 (12.2 %) and anteiso-C 17 : 0 (11.6 %). The whole-cell sugars were ribose, glucose and mannose.

The Potential of Streptomyces as Biocontrol Agents against the Rice Blast Fungus, Magnaporthe oryzae (Pyricularia oryzae)

“…The members of Streptomyces are well-known for their ability to produce a variety of bioactive compounds with different bioactivities such as antibacterial (Schumacher et al, 2003; Ramesh and Mathivanan, 2009; de Lima Procópio et al, 2012; Kumar et al, 2014; Lee et al, 2014a,b; Ser et al, 2016a), antifungal (Lam, 2006), antiviral (Ara et al, 2014), immunosuppressive (Kino et al, 1987), anticancer, and antioxidant properties (Ser et al, 2015a; Tan et al, 2015, 2016). These bioactive compounds have important applications in various fields.…”

Streptomyces colonosanans sp. nov., A Novel Actinobacterium Isolated from Malaysia Mangrove Soil Exhibiting Antioxidative Activity and Cytotoxic Potential against Human Colon Cancer Cell Lines

“…Furthermore, this ecosystem experiences constant fluctuations in salinity and tidal gradient that could trigger metabolic pathway adaptations and possibly lead to the production of pharmaceutically important metabolites. Hence, there are growing interests in the utilization of mangrove microorganism resources and this have subsequently led to the discovery of novel Streptomyces (Hong et al, 2009; Lee et al, 2014d,e). …”

Genome sequence of Streptomyces pluripotens MUSC 135T exhibiting antibacterial and antioxidant activity

“…Previously, MUSC 135 T was shown to produce potent bacteriocin against several pathogens including MRSA ATCC BAA-44 T , S. typhi ATCC 19430 T and A. hydrophila ATCC 7966 T (Lee et al 2014). Our recent fermentation studies on the strain have discovered a significant antioxidant activity when tested with free radical scavenging assay.…”

“…During a screening programming for novel antibiotic producer, Streptomyces pluripotens MUSC 135 T was isolated as novel species isolated from intertidal soil in Pahang state in Malaysia (Table 1). Through a polyphasic approach, the strain was identified as belonging to the genus Streptomyces (Lee et al 2014). Phylogenetic analysis based on partial 16S rRNA gene sequence of MUSC 135 T (accession number: NR_126290) showed highest similarities to Streptomyces cinereospinus NBRC 15397 T (99.18%) and a lower similarity to Streptomyces mexicanus NBRC 100915 T (99.17%) and Streptomyces coeruleofuscus NBRC 12757 T (98.97%).…”
