background :  kefir contains lactic acid bacteria ( lactobacillus , lactococcus , leuconostoc , acetobacter and streptococcus ) and yeasts ( kluyveromyces , torula , candida , and saccharomyces ). kefiran is the polysaccharide produced by lactic acid bacteria in kefir.   methods :  kefiran was prepared from milk containing 0.5% fat and 10 grams kefir grains and was separated from kefir by ethan...

objective: to validate the ethno-therapeutic claim of the traditionally used plant jasminum auriculatum (j. auriculatum) in skin diseases, by evaluating its wound healing potential along with its antioxidant and antimicrobial properties; so as to understand their role in wound healing. materials and methods: excision and incision wound models were used to evaluate the wound healing activity on ...

regarding increasing rate of drug resistance among microbial pathogens, a global search to find new antimicrobial agents from natural compounds with fewer side effects has been considered by many researchers worldwide. bioactive compounds with good antimicrobial activity have been isolated from different algae and cyanobacteria. the current study was performed to determine antimicrobial potenti...

male and female leaves and fruits of eleven different taxons of iranian conifers (cupressus sempervirens var. horizontalis, c. sempervirens var. sempervirens, c. sempervirens cv. cereifeormis, juniperus communis subsp. hemisphaerica, j. excelsa subsp. excelsa, j. excelsa subsp. polycarpos, j. foetidissima, j. oblonga, j. sabina, platycladus orientalis and taxus baccata) were collected from diff...

background: applications of natural ingredients not only increase the shelf life of food but also omit the problems of synthetic preservatives compounds. objective: cinnamon verum essential oil (cveo 0.05, 0.1, 0.15%) and echinacea purpurea extract (epe 0.25, 0.5, 0.75%) were added to kolompe (a traditional cookie in kerman-iran) and their antioxidant and antimicrobial effects were compared wit...

background: due to multiple drug resistance against antimicrobial drugs for treatment of infectious disease, investigations to discovering new antibacterial compounds from natural sources have been designated. objective: according to antimicrobial effects of some capparis species, this study was carried out to evaluate the antimicrobial activity of the extract and fractions of capparis cartilag...

background: lactobacillus plantarum isolated from fermented olives has been extensively studied with the aim of its use in starter cultures for olive or other production fermentations, but little is known about its antimicrobial resistance and its probiotic effects. objectives: the aim of this study was to determine the antimicrobial activity using different strains of l. plantarum isolated fro...

background and objectives: acinetobacter spp. are important causes of nosocomial infections. they possess various antibiotic resistance mechanisms including extended spectrum beta lactamases (esbls). the aim of this study was to determine antibiotic resistance profile of acinetobacter clinical isolates especially among esbl-producing strains and to investigate the antimicrobial effects of oleo-...

rosa damascena, tripleurospermum disciforme and securigera securidaca were used as disinfectant agents and for treatment of some disease in folk medicine of iran. the antimicrobial effects of different fractions of seeds extract of s. securidaca, petals extract of r. damascena and aerial parts extract of t. disciforme were examined against some gram positive, gram negative and fungi by cup plat...

use of natural antimicrobial compounds extracted from plants such as cinnamon as preservative to extend the shelf life has gain much attention. in this study, we evaluated the antimicrobial activity and bio- preservative potential of the methanolic extract of cinnamomum verum bark and its oil against bacillus subtilis , pseudomonas aeruginosae and escherichia coli in ketchup sauce. in order to ...
