โœฆ Synopsis

The esterase isozymes of Paramecium aurelia grown in the presence and absence of bacteria were examined by starch gel electrophoresis. Where present, bacteria make a positive contribution to the esterase zymograms. Different bacteria contribute different esterases. Paramecia growing in axenic medium possess a different esterase which is not produced by the same parmecia growing in the presence of bacteria. This axenic esterase disappears when bacteria are added back to the medium.

Paramecium presents several advantages f o r analyzing the effect of radiation on genetic mechanisms. In tlx first place, its sniall size rnakes it suitable for stiidy with less penetrating radiations. Of course, that characteristic is shared with all those organisms discussed this morning. More imp

Of the 11 inhibitors tested, six microbial and three synthetic inhibitors showed no effect on either pa

Lipid-phosphorus and lipid-galactose content and phospholipid and fatty acid composition of Bifidobacterium bifidum subsp. pennsylvanicum were examined under a wide variety of growth conditions. Cells from 29-C cultures contained less lipid-phosphorus than did cells from 37-C cultures, but their lip

The cation content of Bifidobacterium bifidum subsp. pennsylvanicum was markedly influenced by the washing procedure of the cells, by the growth phase and the temperature, and by the composition of the culture medium. Optimal retention of cations was achieved by washing with 0.25 M MgCl2 at 20C. The
