Introduction to Microbial Media

An introduction to microbial media types, uses and applications. Includes formulations and product selection guide.

Pseudomonas Media and Tests

An article concerning the detection, identification, differentiation, and cultivation of Pseudomonas species.

Differentiation of Escherichia coli from coliforms

There are many other methods of detection to indicate the presence of E. coli. Review common tests and biochemical reactions for this contaminant.

Lactobacilli Basics, Testing & Identification

Information about lactobacilli, rod-shaped, Gram-positive, fermentative, facultative anaerobic or microaerophilic organotrophs. The lactobacillus organtroph belongs to the lactic acid bacteria group.

Inhibition of Cell Wall Biosynthesis by Antibiotics

β-lactam antibacterials inhibit transpeptidase enzymes, preventing peptidoglycan assembly in both Gram-positive and Gram-negative bacteria.

Differentiation and Detection of Escherichia coli, Coliforms and Enterobacteriaceae

An article concerning selective growth media for differentiation and detection of Escherichia coli and other coliforms.

Detection & Molecular Identification of Mycobacteria

Identifying Mycobacterium species crucial due to varying clinical significance; some pathogenic, others not.

Vibrio Detection

Vibrios are motile, curved or comma-shaped bacilli and have a single polar flagella with sheet proteins. They are often found in open water, freshwater and saltwater.

Streptococci - Overview of Detection, Identification, Differentiation and Cultivation Techniques

Streptococci- Overview of Detection, Identification, Differentiation and Cultivation Techniques

Cell Culture Contamination Troubleshooting

Common Cell Culture Problems: Contamination is easily the most common problem encountered in cell culture laboratories, sometimes with very serious consequence.

Clostridia Diagnostic

Clostridia are relatively large, gram-positive, rod-shaped bacteria that can undergo only anaerobic metabolism.

Overview of Chromogenic Media

Selective media enable faster results and visual confirmation for the detection, identification, and enumeration of microorganisms

Salmonella Contamination and Rapid Detection Methods

Salmonella pass through the entire food chain from animal feed, primary production, and into households or food-service establishments.

Campylobacter Detection and Identification

Specific agars and broths support detection and cultivation of Campylobacter, requiring complex media with essential supplements.

Antimicrobial Peptides

Ribosomally synthesized antimicrobial peptides are a promising focus in antibiotic research amidst bacterial resistance and emerging infectious diseases.

Media for Staphylococcus Aureus Detection

Chromogenic media enable the selective detection of S. aureus, which produce bluish-green colonies that are clearly differentiated from other species.
