Microbiology

Microbiological testing includes the controlled analysis of water, beverage, food, pharmaceuticals and other consumer products and their processing equipment to evaluate for the presence of micro-organisms that may cause harm to the user or reduce the product quality or performance.

Microbiological testing is a crucial requirement across many industries worldwide where product, process and human health are influenced by the presence of micro-organisms: living bacteria, viruses, yeasts and molds that are too small to be visible to the naked eye.

International test procedures and standard lab practices have been established to provide strict methods for micro-organism analysis and identification.

Micro-organisms can be harmful or beneficial to the product or process under analysis.

Some diseases of human, animals and plants are caused by unwanted bacteria, yeasts and mold. Other beneficial yeasts and molds are responsible for numerous desirable processes in beer, wine, and food production and biotechnology.

GVS products for microbiological testing include applications and testing for:

Contamination of work surfaces and equipment

Microbiological analysis of:

Potable water

Beer and wine

Waste water

GVS supplies a comprehensive suite of filtration and culturing products used for filtration, isolation and culturing of samples for analysis of micro-organism presence. GVS products meet strict quality and sterility requirements and are designed to quickly and accurately test for the presence of airborne, surface, and liquid micro-organisms.

Sterility:

For Microbiological analysis the sterility of the analysis equipment, including the membranes and culturing media, is important to maintain a clean contaminant free zone. GVS ensures the sterility of its microbiological products through gamma radiation and steam sterilization. All products are labeled with lot number and expiration date for additional control and security.

Product Quality Control:

Microbiological Analysis for good and bad micro-organisms present in processing, production and finished products Contaminants and organisms are quantified and qualified at selected control points throughout the production steps and in the finished product. The main parameter of concern depends on the industry and the finished product under review. Leading parameters are yeast and mold, total bacteria count and E. coli as well as coliforms, fecal streptococci and Pseudomonas aeruginosa.

The Workflow for Microbiological Analysis breaks down into 5 simple steps:

1) Obtain sample for analysis

2) Filter the sample

3) Add Nutrient media

4) Incubate and culture

5) Analyze and enumerate the results

Preparation for Microbiological Analysis includes selection of:

1) membrane type and pore size

2) Nutrient media

3)Filtering Equipment
