Filter sterilize Stock solutions (except vitamins) are considered 1000x. Seawater should be autoclaved and cooled prior to mixing the media. We tend to sterile-filter artificial seawater rather than autoclaving to avoid reductions in dissolved carbon dioxide. A.
2019-3-3 · Sometimes a combination of filtration and heat sterilization is applied. For instance the water used for media preparation is filtered while the concentrated nutrient solution is subjected to heat sterilization. The filtered water is now added for appropriate dilution of the media.
2017-10-17 · •Filter is also used to sterilize off-gases leaving the fermenter. –The concentration of cells in unfiltered fermenter off-gas is several times greater than in air. –Organisms (e.g. pathogens) are harmful to plant personnel or environment. •Two types of air filter –Depth filter (Fibrous filter) Filter
penetration within the filter was determined by removing sections of the filter mats and counts of organisms were determined at various depths. Characteristic of depth type filter media spores were found to penetrate within the fil- ter structure the extent of which was a function of air ve- locity.
