Description

Quantity: 20/Pk.
Unit Size: Each
‘Lactic acid bacteria’ are Gram-positive, catalase and oxidase negative and fastidious in their nutritional requirements. Growth is enhanced considerably by microaerobic conditions. Generally, the ‘lactic acid bacteria’ show delayed growth and smaller colony size than other microorganisms. They may be overgrown in non-selective media, especially if incubation is required for 2-4 days.
• Ease-of-Differentiation: Differentiate gram-positive bacteria on the basis of their ability to produce gas in the Durhams tube.
• Selective: Ammonium citrate and sodium acetate inhibit the growth of certain microorganisms including gram-negative bacteria and molds.
• Ready-to-use:Convenience of prepared media.
• Supports the growth of slower growing lactobacilli.This medium contains gelatin peptone and beef extract that supply essential nutrients and amino acids necessary for growth of lactobacilli. Yeast extract is a source of B-complex vitamins. Dextrose provides an energy source and fermentation of dextrose is detected by gas production in the Durham tube. Polysorbate 80, magnesium and manganese sulfates act as growth stimulants. Selectivity against streptococci and molds is provided by ammonium citrate and sodium acetate.Not all products are available for sale in all territories.
