Enumeration and selective isolation of rumen spirochetes.
Enumeration by means of light microscopy showed that from 0.4 x 10(8) to 2.0 x 10(8) spirochetes were present per ml of bovine rumen fluid. Viable cell counts yielded slightly lower values, ranging from 0.1 x 10(8) to 1.2 x 10(8) spirochetes per ml of rumen fluid. The antibiotic rifampin, which served as a selective agent for rumen spirochetes, was added to agar media used in the estimation of ...
متن کاملThe Comparison of in vitro Digestibility of Wheat Straw by Rumen Anaerobic Fungi of Khuzestan Buffalo and Holstein Cattle
This study was conducted to compare digestibility of wheat straw (WS) by fungi and whole rumen microorganisms (WRM). Dry matter (DM), neutral and acid detergent fiber (NDF and ADF) digestibility of WS were compared with in vitro digestion (IVD), gas production (GP) and specific rumen anaerobic fungi culture (SRAFC). Dry matter, NDF and ADF digestibility of WS by WRM of buffalo (60.80, 49.93 and...
متن کاملMedium without rumen fluid for nonselective enumeration and isolation of rumen bacteria.
Colony counts which approximated those in a habitat-simulating, rumen fluid-agar medium (RFM) were obtained in medium 10, a medium identical to the RFM except for the replacement of rumen fluid with 1.5 x 10(-6)m hemin, 0.2% Trypticase, 0.05% yeast extract, and a 6.6 x 10(-2)m volatile fatty acid mixture qualitatively and quantitatively similar to that in rumen fluid. Single deletion of Tryptic...
متن کاملImproved technique for identification and enumeration of methanogenic bacterial colonies on roll tubes by epifluorescence microscopy.
Methanogenic fluorescent colonies can be clearly identified on roll tubes by using an epifluorescence microscope equipped with a x 2 objective. Methanogenic and nonmethanogenic colonies could be counted in roll tubes prepared from methanogenic enrichment cultures. Late-developing colonies appearing after 25 days of incubation were mainly methanogenic.
متن کاملRoll-your-own endothelial tubes
ust one ingredient can make the difference between a delicious meal and an inedible mess even the dog won't touch. Likewise, 20 years ago the recipe for cultivating endo-thelial cells lacked a vital factor, and many a dish of cells ended up in the trash. The vascular biologists who nabbed the missing ingredient not only simplified the process of growing endothelial cells; their discovery was al...
