Efecto de probióticos sobre el crecimiento de semillas de ostión del pacífico Crassostrea gigas

AquaTechnica, 2020
Se realizó un estudio en juveniles de Crassostrea gigas para investigar el potencial efecto probiótico de Streptomyces spp. (cepas V4, N7 y RL8) y de una mezcla de Bacillus (BMix) teniendo como variable de respuesta su crecimiento.

Strategy for the identification of micro-organisms producing food and feed products : bacteria producing food enzymes as study case [PDF]

, 2020
Recent European regulations require safety assessments of food enzymes (FE) before their commercialization. FE are mainly produced by micro-organisms, whose viable strains nor associated DNA can be present in the final products.

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.

Regulation of Streptomyces Chitinases by Two-Component Signal Transduction Systems and their Post Translational Modifications: A Review

Journal of Pure and Applied Microbiology, 2018
This article reviews the developments related to Streptomyces chitinases regulation and their post translational modifications. Chitinases are enzymes which cleave chitin, a polymer of N-acetylglucosamine to its monomer.

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.

ParA and ParB coordinate chromosome segregation with cell elongation and division during Streptomyces sporulation [PDF]

Open Biology, 2016
In unicellular bacteria, the ParA and ParB proteins segregate chromosomes and coordinate this process with cell division and chromosome replication. During sporulation of mycelial Streptomyces, ParA and ParB uniformly distribute multiple chromosomes ...

Comparative genomics of Streptomyces avermitilis, Streptomyces cattleya, Streptomyces maritimus and Kitasatospora aureofaciens using a Streptomyces coelicolor microarray system [PDF]

Antonie van Leeuwenhoek, 2007
DNA/DNA microarray hybridization was used to compare the genome content of Streptomyces avermitilis, Streptomyces cattleya, Streptomyces maritimus and Kitasatospora aureofaciens with that of Streptomyces coelicolor A3(2). The array data showed an about 93% agreement with the genome sequence data available for S.

Morphological development and cytochrome c oxidase activity in Streptomyces lividans are dependent on the action of a copper bound Sco protein [PDF]

, 2013
Copper has an important role in the life cycle of many streptomycetes, stimulating the developmental switch between vegetative mycelium and aerial hyphae concomitant with the production of antibiotics.

A novel compartment, the 'subqpical stem' of the aerial hyphae, is the location of a sigN-dependent, developmentally distinct transcription in Streptomyces coelicolor. [PDF]

, 2007
Streptomyces coelicolor has nine SigB-like RNA polymerase sigma factors, several of them implicated in morphological differentiation and/or responses to different stresses. One of the nine, SigN, is the focus of this article.
