Experiments were undertaken to test whether peat-based legume seed inoculants, which are prepared with liquid cultures that have been deliberately diluted, can attain and sustain acceptable numbers of viable rhizobia. Liquid cultures of Rhizobium japonicum and Rhizobium phaseoli were diluted to give 10, 10, or 10 cells per ml, using either deionized water, quarter-strength yeast-mannitol broth,...
OBJECTIVES Can the characteristics of persisters in cultures of Mycobacterium tuberculosis also be found in bacilli from the sputum of pulmonary tuberculosis patients? The objective of this study was to explore whether the ability of persisters to grow in liquid but not on solid culture media, as in 100 day static cultures, can also be found in bacilli in sputum. METHODS Serial dilutions of h...
The present study was conducted to isolate and identify phosphorus solubilizing fungi and to evaluate their ability through a qualitative and quantitative experiment. An experiment was carried out with 5 soil samples of Koh- Sepid Lar, Kohgyloyeh and Boyer Ahmad province. The ability of isolates was studied in solid and liquid cultures. Quantitative experiment consisted of blank, four fungi iso...
BACKGROUND Mitotic synchrony is the synchronous progression of a population of cells through the cell cycle and is characteristic of non-diseased airway epithelial cells. However, we previously showed that asthmatic airway epithelial cells are characterized by mitotic asynchrony and are pro-inflammatory as a result. Glucocorticoids can induce mitotic synchrony that in turn suppresses the pro-in...
Megakaryocytes and their precursor cells were sustained in mouse bone marrow suspension cultures for over 4-6 wk. Megakaryocyte precursor cells were detected by their capacity to form colonies of megakaryocytes in semisolid agar cultures. Colony formation was dependent on the presence of medium conditioned by a myelomonocytic leukemic cell line (WEHI-3CM). Megakaryocytes from the liquid and sem...
