제품 개요
원리
Burkholderia Cepacia Selective Agar was developed by Henry and co-workers as an improvement on earlier selective media, giving faster growth and better selectivity for the Burkholderia cepacia complex.¹ Pancreatic digest of casein and yeast extract supply nitrogen, amino acids, vitamins, and growth factors, and sodium chloride maintains the osmotic equilibrium. Lactose and sucrose are the fermentable carbohydrates, and phenol red serves as the pH indicator. Most strains of the Burkholderia cepacia complex oxidise these sugars slowly and release alkaline end-products from the peptones, so that colonies and the surrounding medium turn pink to red after prolonged incubation. Selectivity is provided by crystal violet, which inhibits Gram-positive organisms, vancomycin, which inhibits enterococci and other Gram-positive organisms not suppressed by crystal violet, and polymyxin B with gentamicin, which act together against other aerobic Gram-negative bacilli including Pseudomonas. The medium is specified in the pharmacopoeia for the examination of non-sterile products for the Burkholderia cepacia complex.²
조제 방법
Suspend 50.58 g of powder in 1 L of purified water. Heat with continuous stirring and bring to the boil for 1 minute. Sterilize by autoclaving at 121°C for 15 minutes. Cool to 45-50°C and aseptically add the reconstituted selective supplement. Mix well and pour into sterile Petri plates. Test the finished medium for performance using stable, standard control cultures.
