Lactobacilli Indicators of Freshness
and Probiotic Bacteria

Request Information

To cultivate lactobacilli for subsequent enumeration, Merck provides a range of high quality selective dehydrated culture media. Microorganisms of the genus Lactobacillus, a major part of the lactic acid bacteria group, are not only part of the normal gut flora of humans but are also found on many food products. These microorganisms are among those most frequently used as indicators of freshness in the food and beverages industries. For example, they help to determine the shelf life of most vacuum packaged sliced meat products.

Furthermore lactobacilli can be used as probiotic agents in products such as yogurt. Yogurt that contains Lactobacillus species has been attributed as being effective in relieving digestive problems. A yogurt must contain a certain concentration of lactobacilli to get the status probiotic. To determine that it does so, Merck maintains a wide range of dehydrated culture media for the reliable enumeration of lactobacilli in dairy and milk products.

Safe, Convenient and Consistent Culture Media for Cultivating Lactobacilli

Merck’s uniquely granulated culture media are not merely convenient. They are also safe, meeting the highest industry performance standards as stipulated in ISO 11133. When used in the lab. granulated media cause significantly less dust than powdered ones, leading to less inhalation of hazardous media components that may cause allergic reactions. In addition, this minimizes contamination of the lab environment.

All Merck media are quality controlled in accordance with stringent standards, guaranteeing consistent high quality.
