A Gram-stain-positive bacterium, strain RV15T, forming an extensively branched substrate mycelium and aerial hyphae that differentiate into spiral chains of spores, was isolated from a marine sponge Dysidea tupha collected from Rovinj (Croatia). Comparison of 16S rRNA gene sequences showed that strain RV15T is a member of the genus Streptomyces with highest sequence similarity to the type strains of Streptomyces caeruleatus (98.8 %), Streptomyces cyaneochromogenes (98.6 %) and Streptomyces shaanxiensis (98.5 %). Sequence similarities to all other Streptomyces types strains were below 98.5 %. The multilocus sequence analysis-based evolutionary distance, the average nucleotide identity value and the genome-to-genome distance of strain RV15T and the type strain of S. caeruleatus were clearly below the species cut-off values. Strain RV15T exhibited a quinone system composed of the major menaquinones MK-9(H4), MK-9(H6) and MK-9(H2), typical for the genus Streptomyces . The polar lipid profile of strain RV15T consisted of the predominant compounds diphosphatidylglycerol and phosphatidylethanolamine, moderate amounts of phosphatidylinositol, phosphatidylinositol mannoside, an unidentified lipid and an unidentified phospholipid. Major polyamines were spermine and spermidine. The diagnostic diaminoacid of the peptidoglycan was meso-diaminopimelic acid. The major fatty acids were iso C16 : 0, anteiso C17 : 1 ω9c and anteiso C17 : 0. The results of physiological and biochemical tests allowed further phenotypic differentiation of strain RV15T from its most-related species and hence clearly merits species status. We propose the name Streptomyces dysideae sp. nov. with the type strain RV15T (=DSM 42110T=LMG 27702T).

“…In Table 3 , we depict novel heavy metal-resistant species which were isolated from metal-contaminated areas. The literature review ( Table S1 : List of strains from heavy metal-contaminated areas) suggests that many Streptomyces species with unique characteristics were isolated from soils of metal-contaminated areas [ 32 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 ]. For example, Schmidt et al isolated streptomycetes highly resistant to nickel from a polluted site at the former uranium mine [ 57 ].…”

Biodiversity of Actinomycetes from Heavy Metal Contaminated Technosols

2021

Technosols are artificial soils generated by diverse human activities and frequently contain toxic substances resulting from industrial processes. Due to lack of nutrients and extreme physico-chemical properties, they represent environments with limited bacterial colonization. Bacterial populations of technosols are dominated usually by Actinobacteria, including streptomycetes, known as a tremendous source of biotechnologically important molecules. In this study, the biodiversity of streptomycete-like isolates from several technosols, mainly mine soils and wastes (landfills and sludge) in Slovakia, was investigated. The combination of basic morphological and biochemical characterisations, including heavy metal resistance determination, and molecular approaches based on 16S rRNA gene analysis were used for the identification of the bacterial strains. From nine isolates of Actinobacteria collected from different habitats, one was found to represent a new species within the Crossiella genus. Eight other isolates were assigned to the genus Streptomyces, of which at least one could represent a new bacterial species. Some isolates showed high resistance to Pb, Zn, Cu or Ni. The most tolerated metal was Pb. The results obtained in this study indicate that technosols are a prospective source of new actinomycete species resistant to heavy metals what underlines their bioremediation potential.

“…MSP5A have high potential to be novel species. Due to weak resolution power of the 16S rRNA gene sequence analysis, especially among streptomycetes, a high number of novel species have been described for this genus even with totally identical 16S rRNA gene sequences (Biswas et al 2017;Tang et al 2019;Li et al 2020).…”

Actinobacteria are a biotechnologically important group of microorganisms utilized for their high capacity to synthesize many bioactive substances as well as agriculturally important compounds. In the present study, a culture-dependant approach was employed to isolate actinobacteria from wild legume nodules and their plant growth-promoting activities for indole-3-acetic acid production, atmospheric nitrogen fixation and inorganic phosphate solubilisation was investigated. A molecular approach based on 16S rRNA gene sequence analysis was employed to identify the isolates. After pairwise sequence analysis, six isolates were identified as members of the genera Streptomyces and Micromonospora. All isolates could produce indole-3-acetic acid and utilize atmospheric nitrogen while only one isolate was able to solubilize inorganic phosphate. The isolated actinobacteria are considered to be promising candidates for biological fertilizers especially because of their ability to use atmospheric nitrogen and produce high level of indole-3-acetic acid.
