GranuCult^?BAT agar

半岛bd体育手机客户端 说明

一般描述

GranuCult^?BAT agar supports the growth ofAlicyclobacillusspp. These are aerobic, Gram-positive spore-forming bacteria, with optimum growth at low pH and increased temperatures.Alicyclobacilliare spoilage organisms, especially affecting the quality of fruit juices.
GranuCult^?BAT agar contains glucose as a carbon and energy source. Yeast extract is the source of vitamins, particularly the B-group. Potassium dihydrogen phosphate acts as a buffering system. The low pH and the high incubation temperature inhibit the contaminating flora. This medium contains many trace elements, which supply the specific requirements of theAlicyclobacillusspp. agar is the solidifying agent however, the gel strength is weak due to low pH.

应用

GranuCult^?BAT agar is suitable for the enumeration, detection, and identification ofAlicyclobacillusspp. from fruit juices, other beverages, and their ingredients, environmental samples, including process water and other materials in the area of food production and food handling.
