dependent not just on the type of organisms but also on the growth medium and the number of colonies present on a plate and on culture medium characteristics
colony size
colony size usually stabilizes after
day or two of incubation
slow growth colonies may continue to experience growth past this time, especially if an effort is made to
prevent solid medium from drying out
What are the different types of colony margins?
entire
undulating
erose
lobate
filamentous
What are the different types of colony elevation?
flat
raised
convex
pulvinate
umbonate
What are the different types of colony texture?
shiny to dull
smooth to wrinkled
rough
granular
mucoid
a shiny, smooth, and mucoid appearance tends to be associated with the presence of _________
capsular material
what are the different light transmissions?
transparent
translucent

through completely lacking
opaque
What is the colony pigmentation?
colonies can come in a rainbow of colors
circular, vertical sided plates used to contain agar with tops for aseptic purposes
petri dish
platinum wire heated to an orange glow to sterilize it then is used to transfer a culture from one physical location to another
loop
method of applying cultures to solid medium
streaking
