The preservation of bacterial cultures under paraffin oil.
The preservation of a large collection of bacterial cultures is often a task of major proportions, especially if one wishes to maintain weakly viable and/or fastidious species. Variation in physiological or in morphological characteristics is frequently an undesirable consequence when stock cultures are held for some time, unless special methods are used in the preservation process. The method ...
متن کاملSerum-dependent Phagocytosis of Paraffin Oil Emulsified with Bacterial Lipopolysaccharide
Paraffin oil containing oil red O and emulsified with lipopolysaccharide obtained from Escherichia coli was ingested rapidly by guinea pig polymorphonuclear leukocytes or human peripheral blood granulocytes and monocytes after opsonization by fresh homologous serum. The initial rate of engulfment of the particles was spectrophotometrically assayed by determination of cell-associated oil red O a...

متن کاملA New Method for the Analysis of Bacterial Endotoxins in Ultrapure Paraffin Oil
The paper demonstrates the feasibility of the gel-clot method for the analysis of bacterial endotoxins in water extracts of ultrapure paraffin oil which is a water insoluble oily medical device. Because ultrapure paraffin oil is water insoluble oily liquid, the ultrapure paraffin oil (10 mL) was shaken with 10 mL water for 15 minutes at 2000 rpm, the endotoxin present was extracted to the aqueo...
