Plate 9 See also Figure 4.11c Simple biochemical
screening test (for example, triple sugar iron (TSI)
agar slopes) can be used to determine the spe-
cies of selected bacteria during survey work but in
most cases a series of 20–30 tests will be required.
Illustrated are the Urease test, lysine iron agar (LIA)
and triple sugar iron agar (TSI) slopes used to help
identify Enterobacteriaceae.

used to illustrate the typical biochemical reactions
of ‘type’ cultures representative of bacterial spe-
cies obtained from the American Type Culture
Collection.
