In view of the increase in Saccharomyces cerevisiae mannan content, the culture condition for S.cerevisiae were optimized in this study. The influence of culture condition such as original pH, inoculum size, and temperature on mannan production were evaluated using Response surface methodology. The mathematical model was established by the quadratic rotary combination design. with the order of ...
Pseudomonas syringae inocula containing cell concentrations ranging from 10 to 10 cells per ml were applied to the primary leaves of bean plants. The plants were incubated under conditions of high temperature and illumination and low relative humidity. Bacterial mortality rates and the proportional population decline of the inoculum were lowest at the highest inoculum concentrations. Addition o...
Enterococcus faecalis (E. faecalis) has become a major leading cause of nosocomial endocarditis. Treatment of such infections remains problematic and new therapeutic options are needed. Nine E. faecalis strains were tested: six obtained from patients presenting endocarditis, one with isolated bacteremia, and two reference strains. Antibiotics included daptomycin, alone or in combination, linezo...
The possibility of using mineral oils as a carbon source by bacteria adapted to high oil concentrations was tested in liquid media with different pH values (pH = 5, 7 and 9). Two types of inocula were tested: inoculum I consisted of selected strains used in the bioremediation of oil-contaminated soils and inoculum II contained bacteria isolated from soil samples previously bioremediated at pH =...
In tomato glasshouses, the population structure of airborne inoculum of Botrytis cinerea depends on the production of endogenous inoculum on diseased plants as well as on incoming exogenous inoculum. Both types of inocula may contribute differently to the development of epidemics. Two strains of B. cinerea were introduced in each of four separate compartments of an experimental tomato glasshous...
Epidemiology researchers based at PA, OH, IN, ND, and SD land grant universities are collaborating to provide growers and agricultural industry with timely and reliable disease forecasts for Fusarium head blight (FHB). Knowledge about sources of inoculum, inoculum levels, and weather conditions favorable for FHB development is crucial in devising a handy and reliable disease forecaster. The eff...
This study was conducted in order to compare the accuracy of detection of oxacillin-resistant staphylococci, defined by microdilution MICs, population analyses, and mec gene hybridization, with the Vitek GPS-SA Susceptibility Card with that of the standard inoculum (10(7) CFU) and high-inoculum (10(9) CFU) disk diffusion tests. By the standard inoculum disk diffusion test, 10 of 67 (15%) isolat...
Many researchers have developed various methods for in-planta or floral dip transformation of Arabidopsis thaliana, one of the simple protocol and widely used to produce transgenic Arabidopsis. As the efficiency and ease of getting a transformant is very much time consuming effort and less number of the transformants people get, we have developed a little modified transformation protocol to avo...
ABSTRACT In the Mediterranean Basin, Fusarium oxysporum f. sp. ciceris and the root-knot nematode Meloidogyne artiellia coinfect chickpea. The influence of root infection (after inoculation with 20 nematode eggs and second-stage juveniles per gram of soil) by two M. artiellia populations, from Italy and Syria, on the reaction of chickpea lines and cultivars with partial resistance to Fusarium w...
