Desiccation of agar plates

By Andrew Ramage

The biggest issue facing operators when exposing settle plates in high airflow environments, such as laminar airflow cabinest; class II microbiology safety cabinets and isolators, is the desiccation of the medium during the four-hour exposure time, which is the maximum recommended exposure time.  It is important during exposure that the agar does not shrink from the edge of the petri dish or crack down the middle.  This is to ensure the maximum surface area is constantly exposed to the...

Microbial Quality of Beer

By Andrew Ramage

 

 

After Andy Whittard’s fun piece about agar in cooking, I thought I would write a more light-hearted blog for a change. I’m going to talk about my real passion in life, beer. I’ve been an active member of the Campaign for Real Ale (CAMRA) for many years. You may even have seen my ugly mug on a few volunteer’s posters if you’ve been to beer festivals run by CAMRA! As a microbiologist, you’ll be surprised to read that I’m not really into home brewing.  My love of beer comes from tasting the...

Festive food thoughts

As we approach the festive season, my thoughts like many I’m sure have no doubt turned to enjoying the festivities as well as a welcome break. Preparing the Christmas day feast is a key part and, for all the cooks out there, a little bit stressful. Getting the roast potatoes perfect (duck or goose fat?) and everything onto the table hot and at the same time is a real challenge.

Environmental Monitoring – Remote or Delay Start?

By Gill Power

Reducing contamination risk during environmental monitoring (EM)

When monitoring areas at rest it is important that the operator setting the samples doesn’t influence the sample result.  Placing settle plates and/or setting up active air samplers presents a contamination risk.  This could lead to false positives which create a lot of unnecessary investigative work, which is both time consuming and costly.
