Colony Morphology on SBA at 35oC:      Can grow poorly or not at all on SBA     Tiny, pin-point, translucent colonies after 18-24 hours     Difficult to see individual colonies in growth that is less than 24 hours     Gray-white, opaque colonies less than 1 mm after 48 hours     No hemolysis  Colony Morphology on CHOC at 35oC:      Pin-point, gray-white, opaque growth after 24 hours     1-2 mm, gray-white, smooth, shiny growth after 48 hours     Individual colonies exhibit mature growth at 3…

Colony Morphology on SBA at 35°C, 18-24 hours:      Flat or slightly raised, gray to white with a "ground glass" appearance     Described as "tenacious" or "sticky" like petroleum jelly, shown in the top image     B. anthracis is NOT hemolytic, while B. cereus is hemolytic  Characteristic Features:      After 18 hours of incubation on SBA at 35°C, the slightly undulate margin may show curling, displaying a so-called "Medusa head" or described as comma-shaped protrusions, shown in the lower…

Culture Characteristics:      Growth may be noted as soon as eight hours after inoculation and occurs on most routine media, including sheep blood agar (SBA), chocolate agar (CHOC), and routine blood culture media     Does not grow on MacConkey (MAC) agar  Colony Morphology on SBA at 35°C, 18-24 hours:      Flat or slightly raised, gray to white with a "ground glass" appearance     Described as "tenacious" or "sticky" like petroleum jelly, shown in the top image     B. anthracis is NOT…

Yersinia pestis Colony Morphology on SBA at 35oC:     At 24 hours, colonies are pinpoint and translucent with a gray-white color     Colonies take on a yellow tint as they age, after 48-72 hours, referred to as a "hammered copper" appearance     An irregular or "fried egg" appearance, shown in the lower image, can also be seen at 48-72 hours   Characeristic Features:      Growth at 22-25oC is a hallmark feature of this organism

Lichens are composite organisms consisting of a fungus (the mycobiont) and a photosynthetic partner (the photobiont or phycobiont) growing together in a symbiotic relationship. The photobiont is usually either a green alga (commonly Trebouxia) or cyanobacterium (commonly Nostoc).The morphology, physiology and biochemistry of lichens are very different from those of the isolated fungus and alga in culture. Lichens occur in some of the most extreme environments on Earth
