In this experiment, students see a blue colour change in transformed cells due to the switching on of a gene. The pGAL plasmid gives a blue colour dye due to the production of the β-galactosidase protein by the lacZ gene. IPTG is not required in this experiment since pGAL contains the complete lacZ gene.

A complete range of ready-to-use Petri plates for various microbiological applications.

Supplier: G-Biosciences

The Gram staining method was first described in 1844 by the Danish bacteriologist Hans Christian Gram, after whom the test was named. The Gram staining test for bacteria is one of the most important tests in microbiology and is often one of the first tests performed in the identification of bacteria. The Gram staining method utilises the properties of bacterial cell walls and the stain crystal violet. Gram-positive microorganisms have a higher peptidoglycan and lower lipid content than Gram-negative bacteria in their cell walls and this makes them capable of retaining the Gram stain. This kit is supplied with two strains of bacteria and all the necessary components to carry out the Gram staining.

Used in combination with contact plates, the contact weight enables the standardisation of microbiological surface control between operators. It applies the same constant pressure for a pre-set time on a contact plate. This ensures results are directly comparable. The contact weight meets the ISO 18593 standard, and has a sterilisable stainless steel base and pull-out digital timer.

In this experiment, transformed cells take up a plasmid containing the Green Fluorescent Protein (GFP) gene. The GFP gene was isolated from the jellyfish Aequorea victoria. Transformed colonies expressing the GFP protein are visibly green in normal light but will fluoresce brightly when exposed to longwave UV light.

Used as a selective enrichment medium for the isolation of Salmonella species from food and environmental specimens.

Supplier: VWR Chemicals

Contact plates are ideal for monitoring microbiological contamination of surfaces and air (using an air sampler) inside cleanrooms, isolators, RABS (Restricted Access Barrier), the food industry and hospitals. Triple-wrapping ensures that the package itself does not contaminate the environment, as the first wrapper is removed just before entering a clean area. Plate packaging containing PCA is not irradiated.

R-2A agar is used for heterotrophic plate count of water samples using longer incubation periods.

Supplier: THERMO FISHER DIAGNOSTICS

A gamma-irradiated cold filterable vegetable peptone broth suitable for microbiological media fill trials (MFT) in the pharmaceutical industry. Cold Filterable Vegetable Peptone Broth (cfVPB) is a highly nutritious,
general purpose medium which supports the growth of a wide range of bacteria, yeasts and moulds.

Supplier: Merck

RajHans ChromoSelect Medium is recommended for identification and differentiation of Salmonella species from the members of Enterobacteriaceae, especially Proteus species.

Supplier: VWR Chemicals

Dip slides for microbiological monitoring of surfaces and in liquids. Each slide has media on both sides, with a choice of the same medium, or two different media on the two sides of the slide. This allows sampling of two surfaces with every slide. Testing with dip slides is a safe, reliable, economical and fast indicator of the presence of microorganisms. Dip slides, with a push cap, have a larger contact area.

This kit teaches aseptic handling techniques and cultivation of bacteria in liquid culture media and on solid phase agar plates. This kit is designed to educate students about the various stages of the bacterial growth cycle, i.e. lag, log or exponential, stationary and decline or death phases. The kit also teaches the importance of growing bacteria on solid phase agar plates to isolate single colonies of bacteria. This lab activity involves preparation of culture medium and solid agar plates.

GRIESS-ILOSVAY'S nitrite reagent for microbiology, Millipore®

Supplier: EDVOTEK

The Green Fluorescent Protein (GFP) from the jellyfish Aequorea victoria is used extensively in all areas of science. Many organisms have been transformed with the GFP gene, the gene responsible for bioluminescence in jellyfish. It has proven to be so useful that scientists have mutated it to produce Blue Fluorescent Protein (BFP). In this simple experiment, students transform bacteria either by GFP, BFP or both.

Cefixime trihydrate ≥98.0% (by HPLC) antibiotic, for microbiology

Supplier: G-Biosciences

Antibiotics play a crucial role in the manipulation, screening and killing of bacteria in a range of biotechnology processes. This kit specifically teaches the basic principles of antibiotics, bacterial resistance and susceptibility. Students learn and understand the use of antibiotic resistance in screening for infectious diseases. Utilising a bacterial strain, students learn the effects of different antibiotics and visualise bacterial sensitivity and resistance to the supplied antibiotics. This method involves the use of filter paper discs impregnated with a specified concentration of antibiotics on the surface of an agar plate containing microbial cells. This kit will enable students to analyse the inhibitory effects of different antibiotics on selected bacterial cells and then determine which antibiotic is the most suitable to treat a bacterial infection.
