Development of MMRS (modified MRS Agar) culture medium; the absolute vegetarian culture medium containing plant seed powder in place of beef extract for the growth of probiotics. Vegetarian probiotic foods by definition must be free from all animal-derived ingredients. This research provides an alternative efficacious, cost effective vegetal culture medium. The culture medium developed in prese...
Diatoms of Gomishan wetland (Golestan province, N. Iran), one of the most significant habitats in the eastern shore of the Caspian Sea, has been isolated, purified and identified during 2013. Using serial dilution and streaking on F/2 medium, pure, monoalgal and axenic cultures of the isolates were prepared. The isolates were characterized and identified using micro-morphological studies on the...
Amanita exitialis Zhu L. Yang and T.H. Li is a lethal mushroom species recently isolated in Guangdong Province, China. In this report, a pure culture of this species was obtained for the first time. To confirm the identity of the pure culture, the internal transcribed spacer regions of the nuclear ribosomal DNA of the pure culture and of a typical fruiting body of the species were sequenced and...
to study the effect of strip intercropping pattern with cowpea and soybean on sorghum fodder yield an experiment was conducted at research farm of university of tehran (karaj) during 2005. the experiment was arranged in a randomized complete block design of four replications. the plant proportions included pure culture of sorghum (sss); cowpea (ccc) and soybean (ggg) each in 12 rows; vs differe...
beta-carotene is a carotenoid and known as the most famous natural pigment. microalgae are the most important sources for beta-carotene production. due to the high sterilization cost of pure culture, in this study for the first time, growth, amounts of beta-carotene and chlorophyll in caspian sea microalgae under nutrient deficiencies stress, have been measured and compared with pure microalgae...

The treatments were with 5 levels of monoculture planting pattern included, Festuca ovina L, Festuca arundinacea Schreb, Medicago scutellata L, Agropyron elongatum Anal...
BACKGROUND Early and effective detection of Mycobacterium tuberculosis (MTB), particularly in smear-negative tuberculosis (TB), is a priority for global TB control. Loop-mediated isothermal amplification with a procedure for ultra rapid DNA extraction (PURE-LAMP) can detect TB in sputum samples rapidly and with high sensitivity and specificity. However, the PURE-LAMP test has not been effective...
