Streptomyces alfalfae sp. nov. and comparisons with its closest taxa Streptomyces silaceus, Streptomyces flavofungini and Streptomyces intermedius

International Journal of Systematic and Evolutionary Microbiology, 2016
A novel streptomycete strain, designated XY25T, was isolated from the rhizosphere soil in an alfalfa field in Jingyang, Shanxi, China. The isolate showed optimal growth at 37 °C, and was capable of growing at pH 6-10 and in the presence of 0-6 % (w/v) NaCl.

Lipida of Streptomyces sioyaensis

Agricultural and Biological Chemistry, 1967
Three ninhydrin-positive lipids of Streptomyces sioyaensis were found. These lipids were called substance A, B and C, tentatively. Study on the distribution of these lipids in Actinomycetales has shown that substance A was common in all of the strains tested, and that substance B was found in the limited strains. The substance C was characteristic only

Streptomyces alkaliterrae sp. nov., isolated from an alkaline soil, and emended descriptions of Streptomyces alkaliphilus, Streptomyces calidiresistens and Streptomyces durbertensis [PDF]

Systematic and Applied Microbiology, 2020
A polyphasic study was undertaken to establish the taxonomic position of six representative streptomycetes isolated from an alkaline soil adjacent to a meteoric alkaline soda lake in India. Chemotaxonomic, cultural and morphological properties of the isolates were consistent with their classification in the genus Streptomyces.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Consequences of the deletion of the major specialized metabolite biosynthetic pathways of Streptomyces coelicolor on the metabolome and lipidome of this strain

Microbial Biotechnology
Chassis strains, derived from Streptomyces coelicolor M145, deleted for one or more of its four main specialized metabolites biosynthetic pathways (CPK, CDA, RED and ACT), in various combinations, were constructed for the heterologous expression of ...

A Preliminary Assessment of Yellow Pigment from Streptomyces parvulus C5-5Y

Journal of Pure and Applied Microbiology, 2017
A yellow pigment producing potent strain Streptomyces parvulus C5-5Y (KJ624998) isolated from leather industry was used in this study. The pigmented metabolite exhibited good spectrum of antagonistic activity against common human clinical pathogens ...

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Elucidation of the di-c-glycosylation steps during biosynthesis of the antitumor antibiotic, kidamycin

Frontiers in Bioengineering and Biotechnology, 2022
Kidamycins belong to the pluramycin family of antitumor antibiotics that contain di-C-glycosylated angucycline. Owing to its interesting biological activity, several synthetic derivatives of kidamycins are currently being developed.

Reclassification of Streptomyces caeruleus as a synonym of Actinoalloteichus cyanogriseus and reclassification of Streptomyces spheroides and Streptomyces laceyi as later synonyms of Streptomyces niveus [PDF]

INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY, 2008
Previous studies have proposed that Streptomyces caeruleus is an earlier heterotypic synonym for Streptomyces niveus and Streptomyces spheroides. In this study, phylogenetic analysis of the almost complete 16S rRNA gene sequences of the Streptomyces caeruleus type strains NBRC 13344(T), JCM 4014(T) and NRRL B-2194(T) revealed that S.

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

Advanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.
