Isolation and Identification of Sodium Fluoroacetate Degrading Bacteria from Caprine Rumen in Brazil
The objective of this paper was to report the isolation of two fluoroacetate degrading bacteria from the rumen of goats. The animals were adult goats, males, crossbred, with rumen fistula, fed with hay, and native pasture. The rumen fluid was obtained through the rumen fistula and immediately was inoculated 100 μL in mineral medium added with 20 mmol L(-1) sodium fluoroacetate (SF), incubated a...
متن کاملCharacterization of Several Bovine Rumen Bacteria
DEHORITY, B. A. (Ohio Agricultural Research and Development Center, Wooster). Characterization of several bovine rumen bacteria isolated with a xylan medium. J. Bacteriol. 91:1724-1729. 1966.-Studies were conducted to characterize eight strains of bacteria isolated from bovine rumen contents, by use of a medium containing xylan as the only added carbohydrate source. Based on morphology, biochem...
متن کاملsynthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولGenetically modified rumen bacteria protect sheep from fluoroacetate poisoning
In two separate experiments, test sheep were inoculated with a mixture of four genetically modified strains of Butyrivibrio fibrisolvens, which attained a combined population level of 1 06-10’ cells per ml in each animal. The bacteria had been modified to express the enzyme fluoroacetate dehalogenase. Uninoculated sheep were used as controls. Experiment I included two Merino/ Border Leicester c...
متن کاملAssimilation of Inorganic Cobalt into Rumen Microorganisms
Assimilation of ionic cobalt by axenic cultures of four species of anaerobic rumen bacteria was measured using 6oCo as cobalt (II) chloride. Uptake could be measured in all four species but may not represent active accumulation in the case of Lactobacillus casei and Propionibacterium acnes. Significant uptake (89.5% of 6oCo present) was demonstrated by Selenomonas ruminantium from media contain...
