Improved 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...
متن کاملOptimization of Ph and Temperature for Deoxyribonuclease Producing Bacteria Obtained from Soil
The source of DNA for Deoxyribonuclease (DNase) producing bacteria in soil is the decaying plant cells, dead animal and bial cells. Very few organisms produce DNase extracellularly. Soil samples from different areas of Akola district (India) were screened for deoxyribonuclease production. Of the 100 soil samples screened; 10 efficient deoxyribonuclease producing bacteria were selected for morph...
متن کاملExtracellular deoxyribonuclease production by anaerobic bacteria.
The production of extracellular deoxyribonuclease was examined with anaerobic organisms isolated from clinical specimens. Nuclease activity was extraordinarily common. All strains of Fusobacterium, including eight species, as well as Bacteroides fragilis and B. melaninogenicus, displayed enzyme activity. Whereas the gram-positive bacteria were generally less productive, all strains of Clostridi...
متن کاملUse of ChromID extended-spectrum beta-lactamase medium for detecting carbapenemase-producing Enterobacteriaceae.
ChromID extended-spectrum beta-lactamase (ESBL) culture medium is routinely used for screening ESBL producers. This medium was tested for detecting carbapenemase-producing Enterobacteriaceae isolates from a collection of reference strains and compared to the CHROMagar KPC culture medium previously evaluated for detecting KPC-producing isolates. Producers of IMP-, VIM-, and KPC-type carbapenemas...
متن کاملComparison of test methods for detecting metallo-β-lactamase-producing Gram-negative bacteria.
The recent increase in gram-negative bacteria coproducing multiple classes of β-lactamases has made it difficult to accurately identify metallo-β-lactamase (MBL) producers. In the present study, six methods for detecting MBL producers were compared using 56 gram-negative bacterial isolates that produce various β-lactamases. Sodium mercaptoacetic acid (SMA) and EDTA were used as inhibitors for a...
