the aim of present study was to investigate the effect of individual and co-inoculation of trichoderma species and arbuscular mycorrhizal fungi (amf) on growth, mycorrhization, population of trichoderma, and wilt disease severity in pigeon pea (cajanus cajan l millsp). three species of trichoderma, namely, t. harzianum (th), t. virens (tr), and t. viride (tv) and consortium of amf (myc; mixture...

conclusion these data show that the identified gene encoded tet resistance gene as mfs–type multi-substrate efflux transporter, which contributes to intrinsic resistance on range of structurally unrelated compounds in salmonella species. background tetracyclines (tcs) are a type of broad-spectrum bacteriostatic antibiotics used for treatment of a wide variety of infections. these antibiotics ev...

we consider of the antimicrobial activity on the ag nanoparticles(ag nps) aqueous solutions, which was prepared using a stabilizer, such as poly(n vinyl 2 pyrrolidone pvp , for staphylococcus aureus) s aureus and escherichia coli e coli by measuring the minimum inhibitory concentration mic . antimicrobial effect of ag nps for s aureus and e coli was investigated using disk diffusion method also...

conclusions flushing dental unit waterlines are an effective measure in reducing the number of bacterial contaminants. results bacterial contamination was found in all 24 units at the beginning of daily activity with a mean colony count of 17850. the number of colonies decreased to 3250 following 30 seconds of flushing in 16 units and later to 1837 after flushing for two minutes in 13 units. in...

sterilized soils are commonly used for the study of xenobiotic sorption and as an abiotic control in biodegradation experiments. they are also used for the chemical study of nitrogen and carbon cycle processes and the elimination of the biological factors. in this research the effects of different soil sterilization methods such as autoclaving, fumigating and exposure to ultraviolet and microwa...

Medium conditioned in the presence of human HUT-102 T-cell line cells contains activities stimulating human mixed (colony-forming unit, erythroid, granulocyte, macrophage, megakaryocyte) and erythroid (burst-forming unit, erythroid) colony formation in methylcellulose in vitro and granulocyte colony formation in diffusion chambers in mice. The stimulatory effect of HUT-102-conditioned medium on...

The effects of bone marrow-conditioned medium obtained from colony-stimulating factor-producing tumor-bearing nude mice (G-BM-CM) on mouse and human granulocyte-macrophage colony formation and mouse erythroid colony and burst formation were studied. Addition of G-BM-CM into the mouse granulocyte-macrophage colony-forming system containing colony-stimulating activity more strongly inhibited gran...

AIMS To develop selective media for the enumeration of Botrytis cinerea. METHODS AND RESULTS Two new media, Botrytis Selective Medium (BSM) and Botrytis Spore Trap Medium (BSTM), were developed and compared with currently available media for the enumeration of B. cinerea conidia from the environment. The new Botrytis media proved advantageous over previous media because they were easier to pr...

Positive biodiversity-ecosystem functioning relationships are generally attributed to two mechanisms: complementarity and selection. These mechanisms have been primarily examined using plant communities, whereas bacterial communities remain largely unexplored. Moreover, it remains uncertain how predation by single or multiple predators affects these mechanisms. Here using 465 bacterial microcos...

We investigated the in vitro effects of ASTA-Z-7595, ASTA-Z-7557, ASTA-Z-7654, and 4-hydroperoxycyclophosphamide (4HC) on murine stromal fibroblastoid colony-forming units, committed hemopoietic progenitors (erythroid burst-forming units and granulocyte/macrophage colony-forming units), and pluripotent hemopoietic stem cells assayed by the spleen colony-forming unit (CFU-s) assay. In general, t...
