conclusions this study showed that some properties of antimicrobial substances produced by the ga strain differed from other peptide antibiotics produced by the genus bacillus such as bacitracin, which increases the likelihood of its novelty. results the isolated bacterium was identified as a new strain of bacillus atrophaeus. the antimicrobial substance exhibited heat stability between 25ºc an...

Purpose: The astringent activity of tannins is due to their ability bind with proteins which in turn contributes antimicrobial properties. study aimed at determining the correlation between composite power folklore plant materials and selected herbal formulations relation activity. Protein precipitating (Astringent Power) Tannic Acid Astringent Equivalents extracts were determined. Method: A pr...

The ethanolic extract from stems and leaves of Diospyros gracilipes Hiern showed moderate antimicrobial activity against Staphylococcus aureus (9 mm), Klebsiella pneumonia (7 mm) and Candida albicans (11 mm) using the disc diffusion assay. Fractionation of the extract led to the isolation of lupenone, ursolic acid, corosolic acid, a mixture of 3αand 3βtaraxerols, 3β-E-coumaroyltaraxerol, pinoce...

background: campylobacter infections may lead to serious conditions, including septicemia or other invasive forms of the disease, which require rapid and accurate laboratory diagnosis and subsequently appropriate antimicrobial therapy. the aim of this study was to compare the species distribution and antimicrobial susceptibility pattern of campylobacter spp. strains isolated from patients and f...

The volatile oil from the stem bark of Scutia buxifolia (Rhamnaceae) has been obtained by hydrodistillation and analyzed by GC-MS. Twenty-one components were identified representing 99.93 % of the total oil composition, spathulenol (35.87%), β-cubebene (17.26%), germacrene D (6.43%), linalool (5.19%), carvacrol (4.05%) were the main components of S. buxifolia essential oil. Antioxidant and anti...

Background: The resistance of the bacteria and fungi to the innumerous antimicrobial agents is a major challenge in the treatment of the infections demands to the necessity for searching and fi nding new sources of substances with antimicrobial properties. The incorporation of the essential oils (EOs) in chitosan fi lm forming solution may enhance antimicrobial properties. Howe...
