Nutrition and Physiology of Nitrobacter agilis1

Lack of distinction between Nitrobacter agilis and Nitrobacter winografskyi.

No adequate criteria were established to distinguish between Nitrobacter agilis and N. winogradskyi. However, very gentle preparative techniques permitted demonstration of flagella in N. agilis.

Investigation on Biochemically Processed Castor Seed Meal in Nutrition and Physiology of Japanese Quails

Native de-oiled and treated castor seed meal was subjected to proximate analysis and quantification of anti-nutrients (phytochemicals). Seed cake was treated by biochemical technique of solid state fermentation with Aspergillus niger and addition of calcium oxide (CaO) to give treated castor seed meal (TCSM). One hundred and twenty Japanese quails (Coturnix coturnix japonica) were fed four (4) ...

Prokaryotic Growth, Nutrition and Physiology

Physiology and nutrition of Lampropedia hyalina.

A detailed study of the physiology and nutrition of Lampropedia hyalina revealed that it is an aerobic, cytochrome-containing chemoheterotroph which is limited in its energy sources to a few intermediates (and close derivatives) of the Krebs cycle. Reducing compounds at low levels are potent growth inhibitors. The microbe has no photosynthetic ability (despite its previous taxonomic position wi...

History of nutrition and acid-base physiology.

In the 17th century the notion of nutrition and diet changed in northern European countries. First chemical experiments fostered the idea that salts resulted from a union of acids and bases. Digestion was no more regarded as a process of cooking but a succession of fermentations controlled by a balanced production of acids and alkali. Life seemed to depend on the equilibrium of acids and alkali...
