A Broadened Concept of the Characteristics of <i>Streptomyces hygroscopicus</i>

Abstract

HYGROSCOPICUSest expense that might be encountered is represented by the large vacuum pump required to operate the system across a critical orifice at 28.3 L per min.A smaller pump would be suitable if properly ballasted to main- tain a constant rate of flow through the system.
