Purification of antibacterial compounds from Streptomyces collected from soil sample

Some preliminary results from a collaboration project with NguyenTatThanh University. Dinh Thi Lan Linh, Nguyen Thi Ngoc Yen, Nguyen Huynh Kim and Phan Canh Trinh IntroductionThe Actinobacteria group has well-known for the ability to produce novel antibiotics. Source from agriculture has been studied for many decades, leading to limit the discovery of new species, as … Continue reading Purification of antibacterial compounds from Streptomyces collected from soil sample

Enhancing production of antibiotic by Streptomyces in biofilm culture

Streptomyces spp. can produce the variety of secondary compounds including antibiotic, anti-cancer. At the Mycology Lab, Faculty of Pharmacy, University of Medicine and Pharmacy, we are looking for new antibiotics from lichen-associated Actinobacteria which is a new source in antibiotic discovery. In 2019, we found that ethyl-acetate extract of Streptomyces sp. 4VH3 isolated from Dirinaria … Continue reading Enhancing production of antibiotic by Streptomyces in biofilm culture

Associated Actinobacteria from Vietnamese Lichen

Lichen is a complex model of symbiosis including not only fungi and algae but other bacteria such as Actinobacteria. Of note, Actinobacteria are renowned for capacity to produce various antibiotics. Recently, with discovery of some new secondary metabolites from lichen, lichen-associated actinomycetes have attracted extensive attention. In Vietnam, as of this time, no research has … Continue reading Associated Actinobacteria from Vietnamese Lichen

New finding atraric acid in Vietnamese lichen

This is the first time atraric acid found in Dirinaria applanata, a lichen species popular on Coconut tree in Vietnam. Background Lichen, Dirinaria applanata distributes very popular in Vietnam, however, there are not enough data for this species in terms of secondary metabolites and bioactivity. The aim of this study is isolating and evaluating antimicrobial … Continue reading New finding atraric acid in Vietnamese lichen

Our New Publication for Antimicrobial Activities of Asteraceae Medicinal Plants on Uropathogenic Bacteria

In recent years, antibiotic resistance has become more sophisticated, putting mankind into the postantibiotic era. Many clinical Enterobacteriaceae strains such as Escherichia coli and Klebsiella pneumoniae have extended-spectrum beta-lactamase (ESBL) and carbapenem-resistant Enterobacteriaceae (CRE) [1–3]. Polymyxin plasmid-mediated resistance gene (mcr-1) especially was observed in E. coli strains, which was isolated from animals and in patients with infection during 2011–2014, in China … Continue reading Our New Publication for Antimicrobial Activities of Asteraceae Medicinal Plants on Uropathogenic Bacteria
