OBJECTIVES To evaluate BD MGITTM TBc® technique for identifying the Mycobacterium tuberculosis complex using isolates obtained in liquid and solid media. METHODS A descriptive study was conducted in which 117 isolates were analyzed by the immune-chromatography technique obtained from solid and liquid cultures to identify the Mycobacterium tuberculosis complex. The kappa coefficient was calcul...

A simple and mild procedure for the conversion of anilines into aryl isocyanates is described using the 3-hydroxypropylammonium acetate (HPAA) ionic liquid as a novel and efficient media has been explored in the synthesis of aryl isocyanates from the reaction of substituted urea with sodium nitrite in a water immiscible solvent. This ionic liquid can be easily recovered and reused for many time...

This work is a primary achievement in studying the CO2 and N2–oil systems. To predict gas-liquid relative permeability curves, a Shan-Chen type multicomponent multiphase lattice Boltzmann model for two-phase flow through 2D porous media is developed. Periodic and bounce back boundary conditions are applied to the model with the Guo scheme for the external body force (i.e.,...

BACKGROUND The isolation of non-tuberculous mycobacteria (NTM) has been increasing in South Korea. To date, however, the cause of this increase has not been determined, and it remains unclear whether the use of liquid media has contributed to this increase. The aim of this study was to evaluate the factors associated with NTM isolation and the impact of liquid media on NTM culture. METHODS My...

Burkholderia glumae produced antibiotic substance(s) on agar plate media, but none in various liquid media. Some minor elements in agar were considered to be involved in the antibiotic production. K+, Ca'~, Mg" and NH4 ~ were shown to play significant roles in the production by culturing the bacterium in liquid media supplemented with various inorganic chemicals. Highest production was observed...

Liquid distributions in unsaturated porous media under different gravitational accelerations and corresponding macroscopic gaseous diffusion coefficients were investigated to enhance understanding of plant growth conditions in microgravity. We used a single-component, multiphase lattice Boltzmann code to simulate liquid configurations in two-dimensional porous media at varying water contents fo...

Detection and intensity of urease activity in enterobacteriaceae greatly varies as a function of the media or techniques used, or both. A comparative investigation on several solid and liquid media led us to the following conclusions. (i) Detection of Proteus spp. can be adequately performed with the highly selective solid medium described by Cook (1948), as well as with the different liquid me...

this study was conducted with the main prupose of investigation the effects of culture medium and the concentration of growth regulators on proliferation rate, rooting and the acclimatization of gisela 6 rootstock at khorasan razavi agriculture and natural resource research center during 2011-2012. in this experiment, the proliferation and rooting were performed in six kinds of culture medium (...

BLACK Luffa sponge, derived from dried fruits of Luffa aegyptiaca Mill. (Sponge gourd, Hindi – Ghiya tori), could be a suitable matrix for tissue culture in aseptic liquid culture media. To test this, the response of aroid Philodendron ‘Xanadu’ Hort., an exquisite indoor-ornamental with its beautiful leaves and tangled aerial roots, was studied in vitro by Gangopadhyay and others. A study on in...
