New turbidimetric device for measuring cell concentrations in thick microbial suspensions.
نویسندگان
چکیده
A photoelectric turbidimeter is described for use in measuring cell concentrations in thick suspensions. Its sample cuvette provides a path length continuously adjustable between 0.01 and 20.00 mm. By reducing the path length, it is possible to measure the optical density in thick cell suspensions without dilution. Moreover, the method described is rapid and simple, and only small amounts (less than 1 ml) of cell suspensions are required. The method is applicable to cell concentrations ranging up to 10(9)/ml for yeast.

Properties of microtubule sliding disintegration in isolated tetrahymena cilia
Properties of the sliding disintegration response of demembranated tetrahymena cilia have been studied by measuring the spectrophotomeric response or turbidity of cilia suspensions at a wavelength of 350 nm relative to changes in the dynein substrate (MgATP(2-)) concentration. The maximum decrease in turbidity occurs in 20 muM ATP, and 90 percent of the decrease occurs in approximately 5.9 s. A...
متن کاملMethods of Measuring Penicillin Concentrations in Body Fluids.
Inhibition of bacterial growth is the basis of the three methods commonly used for determining the potency of penicillin solutions. With the Oxford cup method (Abraham et al., 1941; Foster and Woodruff, 1944), penicillin is allowed to diffuse out into agar plates from small glass cups, and the diameters of the zones of inhibition of bacterial growth are measured. In dilution methods (Foster and...
متن کاملUsing lasers to probe the transient light absorption by proteorhodopsin in marine bacterioplankton.
We constructed an experimental apparatus that used lasers to provide the probe beams for measuring the transient absorption kinetics of bacterioplankton that contain proteorhodopsin, a microbial protein that binds retinal and is analogous to animal rhodopsin. With this approach we were able to observe photocycles characteristic of functioning retinylidene ion pumps. Using light from lasers inst...

Introduction: Consumption of vegetable products is increasing commonly in the world because they are recognized as an important source of nutrients, vitamins, and fiber for humans. Salads are among the most widely used foods that are also known as the most contaminated foods in restaurants. This study was conducted to determine the microbial contamination of salad-preparing tables and salad-ser...
