Improved KCN medium.
A semisolid tetrazolium salt agar medium developed for testing sensitivity to KCN is easier to interpret, has a longer storage life, and is less critical in the size of inoculum than is Moeller KCN broth medium.
متن کاملImproved motility medium.
An improved motility medium which permits additional cultural characterization is described. Advantages include maximal motility due to a change in the physical state of the medium from solid to liquid at incubation temperatures, a definitive stab line, preservation of the stab line with nonmotile organisms, and visual delineation of culture motility. In addition, nitrate reduction, nitrogen ga...
متن کاملMechanism of KCN inhibition of photosystem I.
Experiments with chloroplasts and purified spinach plastocyanin suggest a mechanism for KCN inhibition of Photosystem I. KCN inhibition can be bypassed by a detergent or reversed by replacement of the inactive plastocyanin. KCN bleaches and inactivates purified plastocyanin. KCN releases copper from chloroplast membranes and from purified plastocyanin. Cyanide does not bind to the apoprotein pr...
متن کاملImproved medium for sporulation of Clostridium perfringens.
An improved sporulation medium has been developed in which all five strains of Clostridium perfringens tested exhibited a 100- to 10,000-fold increase in numbers of spores when compared with spore yields in SEC medium under comparable conditions. In addition, three of five strains produced a 100- to 1,000-fold increase, with the remaining two strains yielding approximately the same numbers of s...
متن کاملImproved medium for detecting deoxyribonuclease-producing bacteria.
Incorporation of methyl green dye into an agar medium containing deoxyribo-nucleic acid results in an improved medium for detecting deoxyribonuclease-producing bacteria. Use of the dye makes it unnecessary to use acid to demonstrate deoxyribonuclease activity, thus allowing subculture or reincubation of colonies. The improved medium is highly sensitive and can be used for primary isolation of S...
