DEV Nutrient Agar

General-Purpose Nutrient Agar for Total Viable Count in Water and Food Control

DEV Nutrient Agar is a non-selective general-purpose medium used for the cultivation of a broad range of microorganisms and for the determination of total microbial count, especially in water testing and food-control workflows aligned with traditional German DEV methodology.

AS-1197 Total Count Medium ✓ Water Testing DEV / DIN Style

💧 Drinking water & rinse water testing 🧫 Non-selective total viable count medium 🔬 Also useful for routine cultivation

🏆 Water Microbiology Standard

💧 Designed for total germ count workflows

🦠 Broad support for non-fastidious bacteria

📋 COA + SDS available

🏭 Useful for food and beverage water control

🔬 Reliable routine plate count medium

Key Positioning

Classical total count agar for water and food-control labs

🔬 Principle of the Medium

DEV Nutrient Agar is described as a non-selective general-purpose medium supporting the growth of a wide range of microorganisms. Its formulation uses meat peptone and meat extract as nutrient sources, with sodium chloride maintaining osmotic balance and agar providing the solid matrix.

Compared with standard nutrient agar, DEV Nutrient Agar is commonly positioned for determination of total microbial count in water under DEV and related German regulatory methods, while still being suitable for routine cultivation of non-fastidious organisms.

🧬 Applications

💧 Water Testing

Used for determination of total microbial count in drinking water, rinse water, and related water-control applications.

🍽️ Food Control

Also positioned for food-control and beverage-production environments where water hygiene and general bacterial count matter.

🧫 Routine Cultivation

Suitable as a general-purpose non-selective agar for cultivation of bacteria not requiring highly enriched conditions.

🏭 Industrial Hygiene Monitoring

Relevant for potable water, table water, mineral water, and general hygiene monitoring in production systems.

📊 Comparative Plate Count Media Guide

Medium	Primary Role	Best Use	Key Advantage
DEV Nutrient Agar	General nutrient agar for total count	Water and food-control microbiology	Classical DEV-aligned total germ count medium
Standard Nutrient Agar	Routine non-selective cultivation	General laboratory bacteriology	Versatile everyday medium
Plate Count Agar	Standard viable count medium	Food and dairy enumeration	Widely used standard count medium
Low-Nutrient Agar (e.g. R2A)	Recovery of stressed water bacteria	Treated drinking water systems	Better for slow-growing, oligotrophic organisms
