to identify the reservoirs of shiga toxin-producing escherichia coli o157, sensitive detection andisolation methods are necessary. the sensitivity of traditional culture methods can be improved significantlyby the inclusion of an immunoconcentration step, resulting in less false-negative results. in this study,enrichment procedure and immunomagnetic separation (ims) were compared for use in con...
bubble columns are gas- liquid contactors that are widely used in chemical and bio- chemical industries. high mixing that result in high heat and mass transfer rates are amongst their advantages. heat transfer in a bubble column having a bundle of heaters investigated and the variation of heat transfer coefficient with variation in heaters pitch to diameter ratios in a bundle of heaters reporte...
in this study techniques for laboratory identification of dermatophyte fungi through protoplast hybridization were established. firstly, auxotrophic mutants of different species of microsporum and trichophyton were induced and identified. secondly, protoplasts from these mutants were isolated by digestion of their mycelium with novozyme 234 using caci, (o.4m) as an osmotic stabilizer and glycin...
