CKTM Medium (Phyto Semiselective Agar Base)
$45.00 AUD
CKTM Medium (Phyto Semiselective Agar Base) - AS-1392
🌱 Specialized Plant Pathology Medium
Premium semiselective culture medium engineered for isolation and cultivation of plant pathogenic bacteria, particularly Clavibacter and Curtobacterium species.
🔬 Technical Overview & Biochemistry
CKTM Medium utilizes a sophisticated selective inhibition system targeting Gram-negative bacteria while preserving the growth of target coryneform plant pathogens. The medium incorporates specific peptone combinations optimized for fastidious plant pathogenic bacteria, combined with pH indicators and selective antimicrobial agents that create an optimal selective environment.
Biochemical Selectivity: The formulation leverages the unique metabolic requirements of plant pathogenic coryneforms, utilizing specific amino acid profiles and growth factors while incorporating selective agents that inhibit competing saprophytic microorganisms commonly found in plant tissue samples.
Key Features & Applications
🎯 Semiselective Properties
Incorporates selective agents to reduce contamination from saprophytic bacteria and fungi while maintaining optimal growth conditions for target organisms.
🌾 Agricultural Diagnostics
Essential for plant disease diagnosis, seed health testing, quarantine screening, and agricultural outbreak investigations.
🔬 Research Grade Quality
Manufactured under strict quality control with consistent performance for diagnostic laboratories and research facilities.
📊 Enhanced Recovery
Optimized formulation supports growth of fastidious plant pathogenic bacteria with >85% selectivity index.
