Nouioui et al. Standards in Genomic Sciences (2017) 12:4 DOI 10.1186/s40793-016-0216-0 SHORTGENOMEREPORT Open Access High quality draft genome of Nakamurella lactea type strain, a rock actinobacterium, and emended description of Nakamurella lactea Imen Nouioui1, Markus Göker2, Lorena Carro1, Maria del Carmen Montero-Calasanz1*, Manfred Rohde3, Tanja Woyke4, Nikos C. Kyrpides4,5 and Hans-Peter Klenk1 Abstract Nakamurella lactea DLS-10T, isolated from rock in Korea, is one of the four type strains of the genus Nakamurella. In this study, we describe the high quality draft genome of N. lactea DLS-10T and its annotation. A summary of phenotypic data collected from previously published studies was also included. The genome of strain DLS-10T presents a size of 5.82 Mpb, 5100 protein coding genes, and a C + G content of 68.9%. Based on the genome analysis, emended description of N. lactea in terms of G + C content was also proposed.

Received: 13 November 2013; in revised form: 7 January 2014 / Accepted: 21 January 2014 / Published: 13 February 2014 Abstract: Actinomycetes are an important resource for the discovery of natural products with therapeutic properties. Bioprospecting for actinomycetes typically proceeds without a priori knowledge of the bacterial diversity present in sampled habitats. In this study, we endeavored to determine if overall bacterial diversity in marine sediments, as determined by 16S rDNA amplicon pyrosequencing, could be correlated with culturable actinomycete diversity, and thus serve as a powerful tool in guiding future bioprospecting efforts. Overall bacterial diversity was investigated in eight marine sediments from four sites in New Brunswick, Canada, resulting in over 44,000 high quality sequences (x̄ = 5610 per sample). Analysis revealed all sites exhibited significant diversity (H’ = 5.4 to 6.7). -

ABSTRACT Extreme and unusual ecosystems such as isolated ancient caves are considered as potential tools for the discovery of novel natural products with biological activities. Acti- nobacteria that inhabit these unusual ecosystems are examined as a promising source for the development of new drugs. In this study we focused on the preliminary estimation of fatty acid composition and antibacterial properties of culturable actinobacteria isolated from water surface of underground lakes located in Badzheyskaya and Okhotnichya caves in Siberia. Here we present isolation of 17 strains of actinobacteria that belong to the Streptomyces, Nocardia and Nocardiopsis genera. Using assays for antibacterial and antifungal activities, we found that a number of strains belonging to the genus Streptomyces isolated from Badzheyskaya cave demonstrated inhibition activity against Submitted 23 May 2018 bacteria and fungi. It was shown that representatives of the genera Nocardia and Accepted 24 September 2018 Nocardiopsis isolated from Okhotnichya cave did not demonstrate any tested antibiotic Published 25 October 2018 properties. However, despite the lack of antimicrobial and fungicidal activity of Corresponding author Nocardia extracts, those strains are specific in terms of their fatty acid spectrum. -
The Subway Microbiome: Seasonal Dynamics and Direct Comparison Of
Gohli et al. Microbiome (2019) 7:160 https://doi.org/10.1186/s40168-019-0772-9 RESEARCH Open Access The subway microbiome: seasonal dynamics and direct comparison of air and surface bacterial communities Jostein Gohli1* , Kari Oline Bøifot1,2, Line Victoria Moen1, Paulina Pastuszek3, Gunnar Skogan1, Klas I. Udekwu4 and Marius Dybwad1,2 Abstract Background: Mass transit environments, such as subways, are uniquely important for transmission of microbes among humans and built environments, and for their ability to spread pathogens and impact large numbers of people. In order to gain a deeper understanding of microbiome dynamics in subways, we must identify variables that affect microbial composition and those microorganisms that are unique to specific habitats. Methods: We performed high-throughput 16S rRNA gene sequencing of air and surface samples from 16 subway stations in Oslo, Norway, across all four seasons. Distinguishing features across seasons and between air and surface were identified using random forest classification analyses, followed by in-depth diversity analyses. Results: There were significant differences between the air and surface bacterial communities, and across seasons. Highly abundant groups were generally ubiquitous; however, a large number of taxa with low prevalence and abundance were exclusively present in only one sample matrix or one season. Among the highly abundant families and genera, we found that some were uniquely so in air samples. In surface samples, all highly abundant groups were also well represented in air samples. This is congruent with a pattern observed for the entire dataset, namely that air samples had significantly higher within-sample diversity. We also observed a seasonal pattern: diversity was higher during spring and summer. -

STREPTOMYCES GRISEUS (KRAINSKY) WAKSMAN and Henricil SELMAN A
STREPTOMYCES GRISEUS (KRAINSKY) WAKSMAN AND HENRICIl SELMAN A. WAKSMAN, H. CHRISTINE REILLY, AND DALE A. HARRIS New Jersey Agricultural Experiment Station, New Brunswick, New Jersey Received for publication May 10, 1948 Since the announcement of the isolation of streptomycin, an antibiotic sub- stance produced by certain strains of Streptomyces griseus (Schatz, Bugie, and Waksman, 1944), an extensive literature has accumulated dealing with this anti- biotic and with the organism producing it. Although most of the investigations are concerned with the production, isolation, and chemical purification of strepto- mycin, its antimicrobial properties, and especially its utilization as a chemo- therapeutic agent, various reports are also devoted to the isolation of new strepto- mycin-producing strains of S. griseus and of other actinomycetes and to the development of more potent strains. Only a very few of the cultures of S. griseus that have been isolated from natural substrates, following the islation of the two original cultures in 1943, were found capable of producing streptomycin. One such culture was reported from this laboratory (Waksman, Reilly, and Johnstone, 1946), and one or two from other laboratories (Carvajal, 1946a,b). It has been shown more recently (Waksman, Reilly, and Harris, 1947) that by the use of selective methods other streptomycin-producing strains can easily be isolated and identified. In addition to S. griseus, certain other actinomycetes are able to form strep- tomycin or streptomycinlike substances. One such culture was described by Johnstone and Waksman (1947) as Streptomyces bikiniensis, another culture was isolatedbyTrussell, Fulton, andGrant (1947) and was found capable of producing a mixture of two antibiotics, one of which appeared to be streptomycin and the other streptothricin. -

This strain was found to produce a new hydroxamic acid-contain- ing molecule with interesting antimicrobial activities towards various multidrug-resistant micro-organ- isms. Although hydroxamic acid-containing molecules are known to exhibit low toxicities in general, only real evaluations of the toxicity levels could decide on the applications for which this new molecule is potentially most appropriate. Thus, this article provides a new framework of research. Keywords Abstract antimicrobial activity, hydroxamic acid, Streptomyces, structure elucidation, During screening for potentially antimicrobial actinobacteria, a highly taxonomy. antagonistic strain, designated WAB9, was isolated from a Saharan soil of Algeria.
