A Microbiological Assay Method for Thiamine
It is generally recognized that the most useful and convenient means of quantitatively determining members of the vitamin B complex involve microbiological methods. Several methods of this type have been proposed for the assay of thiamine but each one in use today possesses certain inherent disadvantages that limit its value. The fermentation method of Schultz, Atkin, and Frey (1,2), based on t...
متن کاملA Differential Microbiological Assay
Although vitamin B12 can be assayed biologically with mice, chicks or rats, the microbiological method of assay is preferred since it is more rapid and economical. One serious shortcoming of many microbiological B12 assay procedures is the lack of specificity when crude materials are assayed. Crude materials can contain inhibitory or stimulatory factors which cause serious errors in assay resul...
متن کاملAn automated method for the microbiological assay of serum pyridoxal.
A fully automated method for the measurement of serum pyridoxal has been developed. Acid phosphatase was used for dephosphorylation and precipitation of the serum proteins was not required. A chloramphenicol-resistant strain of L. casei was used as the test organism and this removed the need for sterilization. The method gives highly reproducible results, and is suitable for population and inst...
متن کاملChartreusin: production and microbiological assay.
Chartreusin was produced in the fermentation liquors of Streptomyces chartreusis at peak concentrations of 200 to 300 mug/ml. The titers could be increased by 200 to 300% or more by incorporating d-fucose, a part of the chartreusin molecule, into the fermentation media. A microbiological assay with Sarcina lutea could detect concentrations of the drug of 0.5 to 1.0 mug/ml.
متن کاملA MICROBIOLOGICAL ASSAY METHOD FOR p-AMINOBENZOIC ACID
Since the eshablishment of p-aminobenzoic acid as a member of the B vitamin group, a considerable interest has been shown in methods of determination in natural materials. Since known chemical methods are not sufficiently sensitive, it became evident that microbiological tests should be the most practicable. The organism Clostridium acetobutylicum has been used (I) but no general assay procedur...
