Thermo Scientific™ Phenol Red Broth w/1% Maltose

Description

• Determine fermentation reactions of bacteria with Thermo Scientific™ Remel™ Phenol Red Broth w/1% Maltose
• Vera recommended using casein peptone in fermentation test media because of its high growth-promoting qualities 1
• It was reported that peptone could be used with phenol red as the pH indicator in fermentation tests
• Phenol Red Broth is a complete basal medium prepared with phenol red as an indicator, which changes the medium to yellow when acid is produced
• Carbohydrates may be added to the broth base in a final concentration of 1%
• A Phenol Red Broth Base Control tube is used as a negative control for fermentation studies
• A Durham tube may be inserted in a tube of Phenol Red Broth w/1% Maltose to allow detection of gas production
• Can be used in fermentation studies of pure culture of many species of bacteria due to high growth promoting qualities of casein peptone
• Recommended by Association of Official Analytical Collaboration (AOAC) International and the American Public Health Association (APHA) 2-5
• Easy to interpret because of fermentation reaction and gas production
• Yellow color is observed when there is acid production and red-orange color is observed when there is no fermentation
• Bubbles are produced in the Durham tube when gas is produced and no bubbles is produced in the Durham tube when there is no gas production
• Phenol Red Broth w/1% Maltose contains casein peptone that has high growth promoting qualities
• Phenol red is the indicator which helps to determine the reaction by color change
• This medium also contains Sodium Chloride, Phenol Red, Demineralized Water and Maltose
• Sodium Chloride supplies essential electrolytes and maintains osmotic equilibrium of the medium
