Micrococcus
(gcide) | Micrococcus \Mi`cro*coc"cus\, n.; pl. Micrococci. [NL. See
Micro-, and Coccus.] (Biol.)
A genus of Spherobacteria, in the form of very small
globular or oval cells, forming, by transverse division,
filaments, or chains of cells, or in some cases single
organisms shaped like dumb-bells (Diplococcus), all without
the power of motion. See Illust. of Ascoccus.
[1913 Webster]
Note: Physiologically, micrococci are divided into three
groups; chromogenic, characterized by their power of
forming pigment; zymogenic, including those associated
with definite chemical processes; and pathogenic, those
connected with disease.

Micrococcus ureae
(gcide) | Urea \U"re*a\, a. [NL. See Urine.] (Physiol. Chem.)
A very soluble crystalline body which is the chief
constituent of the urine in mammals and some other animals.
It is also present in small quantity in blood, serous fluids,
lymph, the liver, etc.
[1913 Webster]
Note: It is the main product of the regressive metamorphosis
(katabolism) of proteid matter in the body, and is
excreted daily to the amount of about 500 grains by a
man of average weight. Chemically it is carbamide,
CO(NH2)2, and when heated with strong acids or
alkalies is decomposed into carbonic acid and ammonia.
It unites with acids to form salts, as nitrate of urea,
and it can be made synthetically from ammonium cyanate,
with which it is isomeric.
[1913 Webster]
Urea ferment, a soluble ferment formed by certain bacteria,
which, however, yield the ferment from the body of their
cells only after they have been killed by alcohol. It
causes urea to take up water and decompose into carbonic
acid and ammonia. Many different bacteria possess this
property, especially Bacterium ureae and {Micrococcus
ureae}, which are found abundantly in urines undergoing
alkaline fermentation.
