Abstract
Rapid prepn. of silica gels with a pH value of about 7.4 is accomplished by mixing in a vessel 1 volume of lime water and 1 volume of [image]/2 Na silicate and 1.5 volume of acid nutrient of medium No. 1, as given in a previous paper (Jr. Bact. 43: 317-327). Within an intervening period of about 8 min. before gelation takes place, the medium is poured into tubes or Petri dishes and the gels allowed to set for about 2 hrs. They are transferred to an electric oven, the temp. raised to about 100[degree] C, and after 1 hr., the current is turned off. After cooling, they are removed from the oven, put aside under bell jars, and inoculated as desired.This publication has 1 reference indexed in Scilit:
