Probiotics are measured in colony forming units (CFU), which indicate the number of viable cells. Amounts may be written on product labels as, for example, 1 x 109 for 1 billion CFU or 1 x 1010 for 10 billion CFU.

Microbiologists are degree–qualified experts who perform complex research and studies into the impact of microorganisms and microbes on society. They work in laboratories and offices in a range of industries including scientific, professional and technical services, manufacturing, healthcare and education and training.

Biofilms are a collective of one or more types of microorganisms that can grow on many different surfaces. Microorganisms that form biofilms include bacteria, fungi and protists. One common example of a biofilm dental plaque, a slimy buildup of bacteria that forms on the surfaces of teeth. Pond scum is another example.

The ability to generate a single (or “pure”) colony is critical to any further scientific work that may be done with the colony. This is a VERY important tenant of Microbiology, particularly when identification of the isolated colony is needed or further studies with the colony are to be done.
