In EMB agar, most of the strains ofE. colicolonies have a characteristic green sheen. Rapid fermentation of lactose & production of strong acids, thus a rapid reduction in the pH of the EMB agar the critical factor in the formation of the green metallic sheen observed withE. coli, rapid f...
A jelly-like material obtained from marine algae, especially seaweed. It is used as a medium for growing bacterial cultures in the laboratory and as a thickener and stabilizer in food products. The American Heritage® Student Science Dictionary, Second Edition. Copyright © 2014 by Houghton Mif...
The best results were obtained with an agar based diet used for Manduca sexta laboratory rearing. To simplify the preparation and to reduce the cost of this diet, a new formulation was developed. Larvae reared on the new agar-based diet achieved higher pupal rearing efficacy than larvae reared...
Preparation of Inoculum: Inoculum is prepared by picking five distinct colonies of approximately 1mm from 24 hours old culture grown on Sabouraud Dextrose Agar and incubated at 35 ± 2°C. Colonies are suspended in 5ml of sterile 0.85% Saline. Vortex the resulting suspension and adjust the turbid...
Agar is a versatile compound that is most commonly used in laboratory settings to grow microorganisms. It is also used in the food industry, particularly in the preparation of desserts like jellies and puddings. In addition to its gelling properties, agar is utilized in the production of capsules...

It is firstly used in the Berlin laboratory of Robert Koch, who is considered as one of the pioneers of modern microbiology. To culture bacteria on solid surfaces, slices of potato, and then a jelly made from nutrient broth and gelatin, were adopted. However, they did not work well for ...
placing the yeast into an India ink preparation may reveal the encapsulation of the yeast. The capsule is generally better seen in direct clinical specimens from the host and may not be as apparent in wet mounts made from in vitro cultures. This finding occurs because capsule production is indu...
