RESUMO
Elephantopus scaber L. is a useful medicinal plant and has been used as a traditional medicine for various diseases in Asia. In this study, we completed and characterized the chloroplast genome of E. scaber of which the length was 152,375 bp. This circular genome had a large-single copy (LSC, 83,520 bp), a small-single copy (SSC, 18,523 bp), and two inverted repeat regions (IR, 25,166 bp). There were 80 protein-coding genes, 30 tRNA genes, and four rRNA genes in the chloroplast genome of E. scaber. Phylogenetic analysis inferred from 80 protein-coding regions revealed a close relationship between E. scaber and Cyanthillium cinereum (L.) H.Rob. and a sister relationship between Vernonioideae and Cichorioideae subfamilies. The genomic data of E. scaber provide useful information to explore the molecular evolution of not only Elephantopus genus but also the Asteraceae family.
RESUMO
Aims@#To isolate and characterize the lactic acid bacteria (LAB) strains from the “mam chua ca ro” (sour fermented fish) in the South of Vietnam and investigate their potential anti-bacterial properties.@*Methodology and results@#Four LAB strains (MCR1, MCR2, MCR3 and MCR4) were isolated from the "mam chua ca ro" product and their anti-bacterial activity was determined using the spot assay and the paper disc diffusion method. The isolated LABs can inhibit Escherichia coli ATCC 25922, Staphyloccocus aureus ATCC 25923 and Vibrio parahaemolyticus BV016 and produce bacteriocin to control the growth of E. coli ATCC 25922 and S. aureus ATCC 25923, except V. parahaemolyticus. MCR2 was chosen to sequence 16S rRNA of Pediococcus acidilactic.@*Conclusion, significance and impact of study@#On the basis of their prominent anti-pathogenic bacteria activity, LAB strains isolated from Vietnamese sour-fermented fish products were verified as prospective probiotics.
