Antimicrobial Activity of Rubia cordifolia: Methods to Determine Antimicrobial Activity

Conclusion: Rubia cordifolia root extracts showed antimicrobial effects. Using pour plate technique in agar well diffusion method is more sensitive in showing antimicrobial effectiveness than using spreading technique.

In this study, the modified nanocomposite membrane of polyethersulfone (PES) with NH2-MIL-101(Cr) as a metal-organic framework (MOF) is exploited for Candida rugosa lipase (CRL) immobilization. To that end, the various amounts of NH2-MIL-101(Cr) nanoparticles are blended into PES casting solution to fabricate ultrafiltration membrane via phase inversion technique. The incorporation efficiency of NH2-MIL-101(Cr) nanoparticles on the membrane morphology is investigated using various techniques, namely atomic force microscopy (AFM), X-ray diffraction (XRD), and contact angle goniometry. In terms of water pure flux and CRL imm...

Authors: Nguyen TNY, Matangkasombut O, Ritprajak P Abstract Mannan (mannosylated glycoproteins) in the outermost layer of the Candida cell wall may be the first molecules that interact with host dendritic cells (DCs) and activate immune responses that determine disease outcomes. However, little is known about how different mannan structures of common oral Candida species affect DC activation. The effects of heat-inactivated (HI) yeast cells and soluble mannan of Candida albicans, Candida parapsilosis, and Candida dubliniensis on bone marrow-derived DC (BMDC) responses were compared. HI Candida and the mannan exhibi...

The activity of lipase in the DESs was highly influenced by the water activity of the DESs, with optimal lipase activity at a water activity of 0.1. Seventeen DESs containing one or two hydrogen bond donors (HBDs) were used for lipase-...

Streptococcus mutans are considered the most cariogenic bacteria, but it has been suggested thatCandida albicans could increase their cariogenicity. However, the effect of this dual-species microorganisms ’ combination on dentine caries has not been experimentally evaluated. Biofilms ofC. albicans,S. mutans andC. albicans +S. mutans (n = 12/biofilm) were grown in ultra-filtered tryptone yeast extract broth culture medium for 96 h on root dentine slabs of known surface hardness and exposed 8 times per day for 3 min to 10% sucrose. The medium was changed 2 times per day (after the 8 cariogenic challenges and after the ...

Abstract Tunicamycin E (1), featuring a methyl substitution at C-10', was isolated from marine-derived Streptomyces xinghaiensis SCSIO S15077 originated from the South China Sea sediment together with six known compounds, tunicamycin B (2), tunicamycin X (3), tunicamycin A (4), streptovirudin D2 (5), tunicamycin C (6), and tunicamycin C3 (7). The structure of compound 1 was elucidated by detailed spectroscopic data analyses. All the compounds exhibited strong to moderate antibacterial activity against Gram-positive bacteria Bacillus thuringiensis BT01 and B. thuringiensis W102 with MIC values ranging from 0.008 to...

Under favourable conditions, they can colonize the vulvovaginal mucosa, giving rise to symptomatic vulvovaginal cand...
