Lactobacilli MRS Broth

£1,170.37 vat excl.

£1,404.44 vat Inc.

Availability: Out of stock
Lactobacilli MRS Broth is used for the cultivation of lactobacilli and is not intended for use in the diagnosis of disease or other conditions in humans. Lactobacilli MRS broth was originally developed in 1960 by de Man, Rogosa & Sharpe, the medium can be used for confirmatory tests on organisms isolated on MRS Agar. The medium can also be used for enumeration by the Miles and Misra technique. Nutrition is provided by a mixture of carefully selected peptones, glucose, beef and yeast extracts while Tween® 80, magnesium and manganese sulfates act as growth stimulants. Selectivity against streptococci & molds is provided by ammonium citrate and sodium acetate. Occasionally, sterilization of this medium at 121°C for 15 minutes, in some autoclaves, may cause the pH to fall outside of the specified pH limits 6.4 +/- 0.2. In these rare cases, adjustment of the medium using acetic acid or sodium hydroxide is recommended.

m-Enterococcus Agar - 500 g

£127.69 vat excl.

£153.23 vat Inc.

Availability: Out of stock
m-Enterococcus Agar is used for the selective isolation and enumeration of enterococci by membrane filtration in a laboratory setting. m-Enterococcus Agar is not intended for use in the diagnosis of disease or other conditions in humans. m-Enterococcus Agar was first described by Slanetz et al. for the enumeration of enterococci by the membrane filtration technique. In 1957, Slanetz and Bartley modified this medium by adding triphenyl tetrazolium chloride (TTC). Increased recovery and larger colonies were obtained by incubating the inoculated membranes on the agar surface instead of on pads saturated with liquid medium. The membrane filtration method is simple to perform, does not require confirmation, and permits a direct count of enterococci in 48 hours. m-Enterococcus Agar is also referred to as m-Azide Agar. The presence of enterococci is a valuable bacterial indicator for determining the extend of fecal contamination of recreational surface waters. m-Enterococcus Agar is recommended for the detection of fecal streptococci using the membrane filtration technique for water testing. The food industry also has applications for testing enterococci using m-Enterococcus Agar.

Reagent D eliminates DNA from dead cells to prevent false-positive PCR results in food safety testing. This light-sensitive reagent penetrates dead cell membranes and binds to DNA upon light exposure, blocking PCR amplification.

Validated for testing:

  • Enterobacteriaceae
  • Cronobacter
  • Salmonella
  • Legionella
  • Vibrio

in various food matrices including instant milk formula and dairy products. Compatible with Hygiena's DNA isolation kits, Reagent D ensures accurate detection of viable microorganisms in food safety and environmental monitoring applications.

Neogen® Swab-Sampler with 10 mL Letheen Broth is a convenient and quick collection device for environmental sampling and testing over small surface areas.

Sample collection is easy with the attached swab. The vial provides ample headspace for sample addition and vortexing to release organisms from the swab. This sampling device is decontaminated through gamma irradiation for long shelf life. The Neogen® Swab-Sampler is made in the USA with globally sourced materials. The Hazard Analysis Critical Control Point (HACCP) approach is the most widely accepted food safety management protocol worldwide. Sample collection products from Neogen® are a crucial part of this approach to identify potential food-borne hazards and pinpoint where they reside. Portability, stable enrichment media, and easy-to-handle swabs and sponges are designed to test for a wide variety of potential hazards and deliver accurate results. They are engineered to safely gather, hold, and secure contents from the collection site to the lab without leaking or compromising the sample.

The primary use of Letheen Broth is to neutralise the bactericidal action of quaternary ammonium compounds and for determining the phenol coefficient of cationic surfactants. Letheen Broth is also used in hygiene swabbing practices where neutralizing quaternary ammonium compounds are required.

Bacillus cereus Agar Base (PEMBA) - 500 g

£94.52 vat excl.

£113.42 vat Inc.

Availability: Out of stock
Bacillus Cereus Agar Base is used with Polymyxin B and Egg Yolk Emulsion for the isolation and presumptive identification of Bacillus cereus and is not intended for use in the diagnosis of human disease. Holbrook and Anderson described a highly selective and diagnostic medium (PEMBA) for the isolation and determination of Bacillus cereus from food. The medium is formulated to detect small numbers of B. cereus in the presence of large number of contaminants. This medium differentiates B. cereus from other bacteria based on resistance to polymyxin, lack of mannitol fermentation, and presence of lecithinase. B. cereus can be found on vegetables, processed foods, and in nature. B. cereus causes gastrointestinal illness if the organism is allowed to proliferate. Outbreaks of foodborne illness have been associated with boiled and cooked rice, cooked meats, and cooked vegetables.
