General description

Orange Serum liquid media is developed specifically for the isolation and enumeration of micro-organisms that are capable of surviving in fruit juices and citrus products.{2} Fruit juices are generally acidic, with pH values ranging from approximately 2.4 for lemon juice, to 4.2 for tomato juice. The low pH of these foods is selective for yeast, moulds and a few groups of aciduric bacteria. 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. Yeast colonies appear as white, creamy and large colonies. Bacteria colonies will be smaller white and transparent colonies.
Ready-to-use media solve numerous problems in microbiology laboratories where time, equipment and trained personnel are often in short supply. Our media 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. Manufacturing and testing of ampouled media is conducted in strict accordance with precise quality control procedures to ensure optimal growth and maximum shelf life. Reagent grade water is used to clean glassware and make media. Other factors that affect media stability and performance, such as finished product pH, entrained gases, light exposure and temperature are carefully analyzed and controlled during the manufacturing process.

Application

Orange Serum liquid media is used for cultivating aciduric microorganisms (yeast, mold, Lactic Acid Bacteria), particularly those associated with spoilage of citrus products.{3}
