HiMedia M641-100G Lactobacillus MRS Agar, 100 g

Description

Product Overview

The HiMedia M641-100G Lactobacillus MRS Agar is a premium dehydrated culture medium formulated specifically for the selective isolation, enumeration, and maintenance of Lactobacillus species. Each 100 g pouch contains a precisely balanced blend of peptones, yeast extract, glucose, and selective agents that suppress the growth of competing flora while promoting robust Lactobacillus colonies. The agar base is prepared using high‑purity agar powder, ensuring a clear, consistent surface for colony observation. Package dimensions of 4.49 × 2.76 × 2.64 inches and a lightweight 0.113 kg package make storage and handling straightforward for laboratory technicians. The product meets stringent quality standards set by HiMedia Laboratories, a trusted name in microbiological media, and carries an ASIN B00DYOAMU2 for easy reference.

Usage

This agar is ideally suited for a wide range of microbiology applications, including dairy product testing, probiotic research, clinical diagnostics, and quality‑control monitoring in food‑processing environments. To prepare the medium, dissolve the entire 100 g packet in 1 L of distilled water, autoclave at 121 °C for 15 minutes, and allow it to cool to 45‑50 °C before pouring into sterile Petri dishes. Once solidified, the plates can be inoculated with samples using standard streaking or spread‑plate techniques. The selective nature of MRS agar enables clear differentiation of Lactobacillus colonies, which typically appear as large, creamy‑white to slightly yellowish colonies after 48‑72 hours of incubation at 30‑37 °C under anaerobic or microaerophilic conditions. This makes it an essential tool for researchers studying probiotic efficacy, fermentation processes, and microbial ecology.

FAQ

What is the optimal incubation temperature for Lactobacillus on MRS agar?

The recommended incubation temperature ranges from 30 °C to 37 °C. For most Lactobacillus strains, 35 °C provides a balance between rapid growth and colony morphology clarity.

Can the agar be stored long‑term, and what are the storage conditions?

Yes, the dehydrated powder can be stored at room temperature (15‑25 °C) in a dry environment for up to 24 months. Keep the package sealed and protect it from moisture to maintain media integrity.

Is the medium suitable for quantitative enumeration of Lactobacillus?

Absolutely. The selective nature of MRS agar allows for reliable colony‑forming unit (CFU) counts, making it ideal for quantitative assays in food safety and probiotic research.

How does HiMedia ensure batch‑to‑batch consistency?

Each production batch undergoes strict quality control testing, including sterility checks, pH verification, and performance validation against reference Lactobacillus strains. Results are documented and made available to customers upon request.

What support does HiMedia provide if I encounter issues with the medium?
