Abstract

Penicillium chrysogenum was immobilized in polyacrylamide gel prepared from 5% acrylamide monomers (85% acrylamide and 15% N,N′‐methylene bisacrylamide). Penicillin produced from glucose by the immobilized mycelium was 17% of that produced by washed mycelium. However, the activity of penicillin production of the washed mycelium decreased with repeated use. On the other hand, the activity of the immobilized mycelium increased initially and decreased gradually with repeated use. The rate of oxygen uptake of the immobilized mycelium was about 30% of that of the washed mycelium. The immobilized mycelium required oxygen for the production of penicillin.

A previously developed immobilization technique involving latex coatings on solid particulate supports was investigated further for penicillin G production by Penicillium chrysogenum. Several modifications were found to decrease the germination lag time, including a higher spore concentration, a thi

## Abstract Whole cells of __Bacillus__ sp., a bacitracin‐producing bacteria, were immobilized in polyacrylamide gel. The continuous production of bacitracin by an immobilized whole‐cell‐containing air‐bubbled reactor was examined with 0.5% peptone solution. The bacitracin productivity (28 units/ml
