As the bacterial population increases in number the colonies get larger and begin to take on a shape or form. Agar slant cultures are prepared by streaking the slanting surface of the medium in a tube with a stroke of an inoculating needle. Cultivation Of Bacteria Inoculation of culture into agar slant. . When inoculating an agar slant draw the loop containing the inoculum very lightly over the surface in a zigzag formation while being careful not to break the surface. Growing cultures of bacteria on solid media agar plate or slant permits us to view and identify colonial characteristics and also provides a way to separate bacteria in a mixed culture. The slants texture looks very smooth and mucoid. OBJECTIVES Be familiar or be able to describe 1 Preparation of bacterial smears from pure broth and slant cultures 2 Distinguish a good smear from a poorly prepared smear 3 Differences in procedure for making smears from broth ...
