Buffered Peptone Water micro-environment

Buffered Peptone Water environment as BPW also called buffer Pepton

Buffered Peptone Water Environment used to get rich before use in order to increase the likelihood of recovering the species Salmonella bacteria were injured in food and increase student selectivity.

Buffered peptone Water environment component – Gms/Liter

The formula was adjusted and standardized to match the active parameters.

Currently, Chemical environmental microbiology Buffered Peptone Water contains the manufacturer as: Merck, Titan, Himedia, Labm,Scharlau ... With the price and quality vary.

Depending on the application that this cultured environment are suitable processing. So you note when ordering. For further information contact Mr. Options 0902106379 to be advised.

How to preserve: Preserved under temperature 30 degrees C in airtight container . For aqueous phase was then preserved in cool temperatures from 2-8 degrees C. Use before the expiry date indicated on the label.

How to mix Buffered Peptone Water Environment

User weight techniques 2 odd quantities 20.00 grams and mixed in 1000 ml distilled water. You can use heat to dissolve completely in this environment.

Handle sterilized by cleaning the nine at a pressure 15 lbs or 121 degrees C within 15 minutes. If want to add ECO157 infection supplements:H7 to isolated the bacteria Escherichia Coli O157 from food has been heated and cooled at a temperature 45-50 degrees C. Mix well and let in the tubes or sterile vase.

Buffered Peptone Water environment principles

Buffer solution Peptone Water is salmonella cultured environment used to get rich before they can be used to help restore the bacteria Salmonellae were hurting after putting on selective environments. Environment before this enrichment does not contain inhibitors, be enriched and facilitated to restore damaged cells in the process of food preservation.

Two researchers Edel and Kampelmacher has acknowledged the injury happened Salmonella bacteria in the process of food preservation is due to temperature, dry humidity, high osmotic pressure, the preservatives and the change of pH levels.

Pepton Water buffer -BPW in the stage before enrichment help restore damage cells sensitive to low pH. This is especially important in plant samples. This solution can be used to test the dry bird food.

In experiments related to the isolation of Salmonella from meat was infected, before get rich in salt water Buffered Peptone in 37 degrees C within 18 hours before the selective in Tetrathionate Brilliant Green Bile Broth environment for better results with direct selection method.

Lactose Broth is often used as the enriched environment but can be detrimental in the Salmonella recovery.

Proteose Peptone containing chemicals including Carbon, Nitrogen, Vitamins and minerals. Sodium chloride to maintain osmotic balance with phosphate buffer solution environment. Align the lift has many nutrients increased support for the bacteria to injury. Phosphate buffer with the purpose of preventing the bacterial lesions caused by changing the pH of the environment.

Dental implants 10 Gram 50 ml sample in environment and incubated at temperatures 35-37 degrees C in 18 now. Transfer 10 ml from this environment to 100 ml Tetrathionate Broth and incubated at 43 degrees C in 24-48 now . Then cultured on selective environments. Check the disc for the bacteria Salmonella typical Club.
