MacConkey Agar for Differentiation of Enteric Bacilli, 500 g, Acumedia, 7102A

Acumedia® MacConkey Agar for Differentiation of Enteric Bacilli, 500 g, 7102A

Features:

• MacConkey Agar is used for isolation and differentiation of Gram-negative enteric bacilli in laboratory setting
• Not intended for use in the diagnosis of disease or other conditions in humans
• Medium recommended by the Harmonized USP/EP/JP for isolation and identification of Escherichia coli from non-sterile products
• Conforms to USP/EP/JP performance specification
• Gelatin serves as source of carbon and nitrogen
• Lactose is fermentable carbohydrate and sodium chloride maintains osmotic balance
• Bile salts and crystal violet act as selective agents inhibiting many Gram-positive bacteria
• Escherichia coli can ferment lactose to produce acid which results in a pH drop indicated by neutral red resulting in pink colonies
• Enough acid production will cause precipitation of bile salts resulting in bile precipitate or halo around lactose fermenting bacteria
• Non-lactose fermenting bacteria such as Salmonella spp. grow but remain colorless with no bile precipitate
• According to the Harmonized USP/EP/JP, MacConkey Broth is used as selective enrichment broth, with subculture performed onto MacConkey Agar
• Appearance: light red powder solid
• CAS No.:
  • Sodium Deoxycholate: 302-95-4 
• pH: 6.9 – 7.3
• Solubility: soluble in water
