BactID

A Tiny Earth tool

This is a teaching tool designed for Tiny Earth Students to help identify their bacterial isolates based on biochemical testing. This tool was created using Bergey’s Manual of Determinative Bacteriology by SL Mathews.

Step 1: Primary Tests

Enter the results for your unknown organism. These first five tests will narrow down the possibilities.

Gram Stain
Catalase
Oxidase
Gelatinase
Glucose Utilization

Step 2: Secondary Tests

Now, let's refine the results. Please enter the data for the remaining tests. Select "N/A" if you did not perform the test.

Amylase (Starch Hydrolysis)
Hydrogen Sulfide (H₂S)
Indole
Motility
Lactose Utilization
Mannitol Utilization
Hemolysis

Step 3: Identification Result

Step 4: 16S Validation

Please perform 16S rDNA sequencing on your isolate. Analyze the results to determine the genus, then enter your findings in the form below.
