An improved agar medium for growth of Geobacillus thermoglucosidarius strains.
Geobacillus species have potential applications in many biotechnological processes. They are fastidious in their vitamin and amino acid requirements. A new semi-defined agar medium (SDM) was developed which gave consistently high viable cell counts of various G. thermoglucosidasius strains (5×108-6×108cfu/ml) under aerobic conditions at 70°C.
متن کاملAcetamide agar medium selective for Pseudomonas aeruginosa.
A synthetic base of acetamide and salts in agar permitted isolation of small numbers of Pseudomonas aeruginosa from swarming Proteus and other gram-negative species.
متن کاملComparison of Aspergillus niger spore production on Potato Dextrose Agar (PDA) and crushed corncob medium.
Minimizing the number of generations through which a culture passes from the initial culture until its recovery at the fi nal stage of fermentation is a general principle. For fi lamentous fungi, a large number of generations can cause the appearance of low-yield producing variants and mutant strains, which are generally genetically unstable. The use of successive sub-cultures can decrease the ...
متن کاملColistin-oxolinic acid-blood agar: a new selective medium for streptococci.
The development and evaluation of a new selective medium (colistin-oxolinic acid-blood agar) for streptococci is described. Streptococci of medical and veterinary importance grew well on the medium. Gram-negative organisms, staphylococci. Bacillus spp., and coryneforms are all inhibited. It was concluded that the medium is valuable for the isolation of streptococci in pure culture from mixed fl...
متن کاملAcid Fuchsin Methylene Blue Agar: a New Differential Medium for Enteric Bacteria.
Despite the development of successful selective media favoring the more pathogenic members of the Enterobacteriaceae, media of primarily differential nature have not been entirely satisfactory for several reasons, such as the following: (1) Generally only colonies of lactose fermenters are colored, whereas the colorless colonies of nonfermenters tend to be masked by the diffusion of dye from fe...
