bacteriums

In the remaining three, where pea-meal or hay were employed, there the bacteriums were seen. So also in the other series, the one case in which nothing was found was a case in which flour was used, and in the remaining five the most numerous and distinct bacteriums were seen in the hay infusion.

The normal microzymas of plants and of animals may develop into bacteriums; and many forms of both may exist in the same plant. The inoculation of the bacterium in a plant or animal causes their increased number, not by multiplication, but by so modifying the medium that the normal microzymas more readily develop themselves into bacteriums.

Differences in the molybdenum iron proteins from these two bacteriums are reflected in e.p.r. titrations, the relative reduction sequence of the redox centres, their midpoint reduction potentials, and the relaxation behaviour of the S=3/2 e.p.r. signal.

Some bacteriums and simplest organisms radiate the light (Prosser and Brown, 1967; Chumakova and Gitel’son, 1975).
