This agar is used to identify organisms that are capable of producing the enzyme lipase. This enzyme is secreted and hydrolyzes triglycerides to glycerol and three long chain fatty acids. These ...

SINCE Cooper and Woodman 1 proposed on theoretical grounds that the formula should explain the size of inhibition zones, under specified experimental conditions, evidence on the validity of this ...

An inoculating loop can be used to transfer bacteria. It is sterilised by heating it to red hot in a Bunsen flame, before and after use. To inoculate the agar, lift the lid of the Petri dish and tilt.

This is a differential medium. It tests the ability of an organism to do several things: reduce sulfur, produce indole and swim through the agar (be motile). SIM is commonly used to differentiate ...

Pour the sterile agar plates and allow to set fully. Reason - this provides the selected bacterium with all the nutrients needed to grow. Reason - this allows the bacteria to spread out and to ...

A scientist’s quest for microbes that produce purple pigments led her to the vibrant world of natural dyes, where biology and ...

Gelatin offered some advantages, but it was easily consumed by microbes and melted at the high temperatures needed to ...

The nifty gelatin and egg white substitute can be found in either powdered or flake form -- but be sure to look for food-grade agar and not the type used for culturing bacteria in laboratories. Packed ...

Citrus trees showing natural tolerance to citrus greening disease host bacteria that produce novel antimicrobials that can be ...

Chloe swabs parts of her body, or plants, and transfers the samples to petri dishes with a special growth medium inside called agar. The bacteria samples are covered and allowed to multiply into ...
