The effect of drying upon the viability of bacteria
1912
Experimental biology and medicine
The curve of viability, measuring the rate of decrease among bacteria exposed to an unfavorable environment, has been determined for many conditions. Drying is known to cause a rapid elimination, but no exact quantitative determinations have been made. In the experiments here reported, colon bacilli were used. One cubic centimeter of a @-hour broth culture was mixed with 2% grams of sea sand spread out in an ordinary Petri dish. Duplicate dishes prepared in this way were covered with porous
