Produktbeschreibung

Determination of deoxyribonuclease activity, particularly of Staphylococcus aureus and Serratia marcesans. Jeffries et al. described a procedure for detecting the production of deoxyribonuclease by bacteria and fungi. After 18-24 hours of growth on DNA containing agar medium, the agar surface was flooded with 0.1N HCI. A clear zone around growth of the colonies indicated a positive reaction. A correlation between coagulase production and DNase activity was observed by many workers. Appearance: Beige, homogeneous, free flowing powder Solubility: Light amber, trace to slight haze pH (4.2%): 7.30.2 Microbiological Analysis: Serratia marcescens ATCC 8100, Good Staphylococcus aureus ATCC 25923, Good Staphylococcus epidermidis ATCC 12228, Good Streptococcus pyogenes ATCC 19615, Good *Results were obtained from type cultures after incubation at 35-37C and observed after 18-24 hours
