Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Physiology and Pathogenesis
Biochemical characteristics, enzymes made, other characteristics that may be used to identify the organism; contributions to environment (if any).
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Biochemical Characteristics:
Phenol Red Broth:
•Glucose fermentation: (+) result; broth was yellow indicating glucose fermentation
•Lactose fermentation: (-) result; broth was red—no change in broth??
•Sucrose fermentation: (-) result; broth was red—no change in broth??
problems encountered during procedure:
Starch Hydrolysis: (+) result; clearing was present on starch agar media; soil organism produces the α-amylase enzyme
Casein Hydrolysis: (-) result; no clearing in skim milk agar; soil organism does not produce the casease enzyme
Gelatin Hydrolysis: (+) result; solid broth turned to liquid; soil organism produces the gelatinase enzyme
DNA Hydrolysis: (+) result; clearing in agar; soil organism produces the DNase enzyme
