Science - Biology (-tech,-chem,micro-) / Microbiology- virus titrations | | German term or phrase: Zehnerstufen | Der Ausgangstiter der Virussuspension betrug 7,4 log IDsJml. Aus den in der Tabelle 1 wiedergegebenen Daten ist ersichtlich, daB die 0,7 %ige Formaldehyd-L6sung den Rotavirus-Titer nach einer Einwirkzeitvon zwei Minutenum 0,4 Zehnerstufen reduzierte.
Nach fOnf und 10 Minuten betrugen die logarithmischen Reduktionsfaktoren 0,6 und 0,9. |

Stability of rotaviruses to various physical factors. (i) pH. FH4232 and SAll retained infectivity following treatment at a wide range of pHs (Table 1). Their infectivity was unaltered after treatment at pH 3 to 11. Strain FH4232 was completely inactivated at pH 2.5 and 11.5 however, while SAl exhibited greater resistance to extremes of pH, losing 2 log units of infectivity at pH 2.5, 4 log units at pH 2.0, and 2 log units at pH 11.5. SAl was completely inactivated at pH 12.

At pH 6.0 and 15°C, 0.1% alcalase reduced SA-11 titer by 0.75 log in 24 h, and by 1.25 log in 120 h. At 25°C and pH 6.0, 0.1% alcalase reduced the titer by 2.25 log after 24 h, and by 2.75 log in 120 h. At pH 6.0 and 15°C, 1% alcalase reduced SA-11 titer by 1.50 log in 24 h and by 1.75 log in 120 h. At the same enzyme concentration and pH, but at 25°C the titer was reduced by 2.75 log in the first 24 h and by 3.25 log at 120 h. These results show that the alkaline protease alcalase is capable of inactivating SA-11 virus to a certain degree depending on conditions.
