Analytical microbiology. IV. Gravimetric methods.
In these methods, the response of the test organism to graded concentrations of the substance being assayed is determined, after a suitable incubation period, by measurement of the amount of growth in terms of dry cell weight. Under the conditions of assay, this weight is proportional to the concentration of the limiting factor. By comparing the response of the test organism to the sample being...
متن کاملSpecial Rumen Microbiology
Bacteria make up about half of the living organisms inside of the rumen. However, they do more than half of the work in the rumen. The bacteria work together. Some breakdown certain carbohydrates and proteins which are then used by others. Some require certain growth factors, such as B-vitamins, which are made by others. Some bacteria help to clean up the rumen of others’ end products, such as ...
