Our partner company MOCON Inc. now sell and market the GreenLight 900 series globally. For more information on the GreenLight 900 series, please visit www.mocon.com/foodsafety.php

The GreenLight™ range of food safety tests provide easy, same-day detection and enumeration of bacteria in food samples by measuring bacterial oxygen consumption (bacterial respiration) and equating oxygen consumption to microbial load.

As bacteria in the test sample grow and respire they deplete O₂ which is detected as an increase in the GreenLight™ probe signal above the baseline level. The time required to reach this increase in signal is used to calculate the cfu/g of the food sample, based on a pre-determined calibration.

Benefits:

Extremely cost effective and fast with the ability to screen up to 384 samples in parallel.

• Same day results – results in hours, allowing for better inventory control, and immediate screening of incoming raw materials

• Easy sample preparation – same as for standard agar plate method, but without the need to perform multiple sample dilutions –

• Simple 'mix and measure' protocols

• Detects live bacteria – Excellent correlation with standard agar plate method

• Save on time, labor, consumables, remove the need for agar plates

• AOAC certified, licence no.061002. Approved for raw meat and poultry

The GreenLight™ 900 series has three formats available depending on throughput and sensitivity required.

• GreenLight Model 960 for high throughput:
• GreenLight Model 930 model for high throughput: up to 432 samples (9 carousels) per day
• GreenLight Model 910 model for lower throughput requirements: 1 - 50 food tests per day

Pharma:

The MitoXpress-Xtra assay provides rapid enumeration of bacterial load by measuring bacterial oxygen consumption and equating consumption rate to microbial load.

The assay is a simple 'mix and measure' test. Samples are prepared as for agar plates, dispensed into the wells of a standard 96-well plate together with the oxygen-sensing probe, covered with mineral oil, and measured automatically on a fluorescent reader at 30°C. The assay is based on the ability of O2 to quench the excited state of MitoXpress, a soluble, phosphorescent oxygen-sensitive probe.

Benefits

• The test provides sensitive, rapid enumeration of bacterial load without the need to conduct lengthy and tedious colony counts on agar plates

• Fast, simple, high throughput, assay using standard plates and fluorescent reader

• Samples prepared, and assays run, and results obtained in a single 8 hour working shift

• Data obtained and counts calculated automatically

• Easy sample preparation, same as for agar plate. Total assay preparation time – under 1hr per plate (up to 96 samples)

• TVC level 1x106 Cfu/g detected in 5.5hours, 1x108 Cfu/g detected in under 45 minutes

• The software provides easy-to-read graphical representation of measured fluorescent profiles in real time, as shown by the examples in the figure below, allowing the operator to make visual semi-quantitative analysis
