Abstract
The effect of pressure on the morphology and ultrastructure of E. coli IAM 1996 with particular reference to filament formation is studied. The cells were grown in a nutrient broth supplemented with 1.0% glucose and incubated at 25.degree. C for 60 h at ambient or increased pressure of 400 atm. By EM, the cells grown under high pressure exhibited cell elongation with a decrease in septum formation. More than 70% of the cells under high pressure exceeded 20-50 .mu.m in length, with some longer than 100-200 .mu.m as compared with 2-4 .mu.m for normal cells. Cytoplasmic dense granulations in the abnormal cells were also observed.This publication has 1 reference indexed in Scilit:
