Metabarcoding expands knowledge on diversity and ecology of rare actinobacteria in the Brazilian Cerrado

Folia Microbiologica
Rare and unknown actinobacteria from unexplored environments have the potential to produce new bioactive molecules. This study aimed to use 16 s rRNA metabarcoding to determine the composition of the actinobacterial community, particularly focusing on rare and undescribed species, in a nature reserve within the Brazilian Cerrado called Sete Cidades ...

Isolation and screening of proangiogenic and antiangiogenic metabolites producing rare actinobacteria from soil

Journal of Applied Microbiology, 2017
Angiogenesis is a physiological process that has important impacts on the pathology and healing of various diseases, and its induction or inhibition by bioactive actinobacterial metabolites can help the treatment of some diseases. In this study, the effects of actinobacterial extract in the process of angiogenesis have been explored.In this research ...

Isolation and characterization of bioactive compounds with antibacterial, antioxidant and enzyme inhibitory activities from marine-derived rare actinobacteria, Nocardiopsis sp. SCA21

Microbial Pathogenesis, 2019
A rare actinobacteria strain designated SCA21, producing bioactive metabolites was isolated from marine sediment of Havelock Island, Andaman and Nicobar Islands, India. Analysis of 16S rRNA sequences suggested that the strain SCA21 belonged to the genus Nocardiopsis.

Glutathione: A powerful but rare cofactor among Actinobacteria

, 2019
Glutathione (γ-l-glutamyl-l-cysteinylglycine, GSH) is a powerful cellular redox agent. In nature only the l,l-form is common among the tree of life. It serves as antioxidant or redox buffer system, protein regeneration and activation by interaction with thiol groups, unspecific reagent for conjugation during detoxification, marker for amino acid or ...

Rare taxa and dark microbial matter: novel bioactive actinobacteria abound in Atacama Desert soils

Antonie van Leeuwenhoek, 2018
An "in house" taxonomic approach to drug discovery led to the isolation of diverse actinobacteria from hyper-arid, extreme hyper-arid and very high altitude Atacama Desert soils. A high proportion of the isolates were assigned to novel taxa, with many showing activity in standard antimicrobial plug assays. The application of more advanced taxonomic and

Isolation and screening of rareActinobacteria, a new insight for finding natural products with antivascular calcification activity

Journal of Applied Microbiology, 2017
Vascular calcification (VC) is a significant pathological process in some life-threatening diseases. Several pathological mechanisms, including transdifferentiation of vascular smooth muscle cells to osteoblast-like cells and apoptosis are involved in VC. Compounds with an inhibitory effect on these processes are potentially efficient medications.

Cytotoxic Angucyclines fromAmycolatopsissp. HCa1, a Rare Actinobacteria Derived fromOxya chinensis

Planta Medica, 2011
Two new angucyclines, named (2R,3R)-2-hydroxy-8- O-methyltetrangomycin (1) and (2R,3R)-2-hydroxy-5-O-methyltetrangomycin (2), together with eight known compounds (3-10), were isolated from the culture of Amycolatopsis sp. HCa1, a rare actinobacteria isolated from the gut of Oxya chinensis.
