fecal coliforms
一般描述
m-FC Broth with Rosolic Acid is used for the detection and enumeration of fecal coliforms in water and other liquid samples by membrane filtration technique. This medium is based on the property that fecal coliforms grow at 44-45°C. Enzymatic digestion of animal tissue provides nitrogen, carbon, and minerals in M-FC Broth with Rosolic Acid. Yeast Extract is a source of vitamins and trace elements. Sodium Chloride maintains the osmotic balance. Lactose serves as a carbohydrate source. Bile Salts inhibit the growth of Gram-positive bacteria. Rosolic Acid is the differential indicator system. Coliforms form blue colonies, whereas non-coliforms form gray-colored colonies.
应用
m-FC Broth with Rosolic Acid is suitable for testing waste and effluent waters for fecal coliforms.
特点和优势
- Ready-to-use Liquid ampoule media solve numerous problems in microbiology laboratories where time, equipment, and trained personnel are often in short supply.
- They are available in convenient, single-test 2 mL plastic ampoules, eliminating the manipulation of glass ampoules and avoiding the waste and spoilage associated with bulk packaged media.

Target Microorganisms: 粪大肠菌群
粪大肠菌群显示为蓝色，其它菌落显示为灰色至乳白色。 在极少数情况下，膜可能已确认粉红色粪大肠菌群。 这可能是由于培养垫上培养基不足、培养期间培养皿中过度的水分损失或菌落观测偏晚。
