"Ward's Phenomena"

Includes Examples of the Three Basic Morphological Types

Anabaena is a genus of filamentous, un-branched Cyanobacteria consisting of bead-like cells and enlarged spores or heterocysts.

This colonial cyanobacteria is structured as several cells bound together in a gelatinous "mucilaginous sheath".

Certain strains of bacteria have their own pigments, creating a rainbow of different natural colors. This set includes bacterial cultures with a variety of different colors.

Taking their name from the bluish pigment that most of these organisms share, each jar contains a broad sample of several types of cyanobacteria.

This organism is a common environmental isolate, and can be found in soil as well as in industrial settings.

This organism is commonly found in soil and water, and is also associated with spoiled food. It produces a diffusible fluorescent pigment.

Colorless, most widely dispersed of the Serratia species. 

This spore-forming, thermophilic organism is commonly used for germicidal and sporicidal testing due to its ability to withstand higher-than-normal temperatures.

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.

Red-pigmented halophile from evaporating salt ponds; requires 25% salt medium, lyses easily in plain water, releasing DNA.

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.

This organism is commonly isolated from sewage, water, soil and dairy products, as it is a normal part of intestinal flora.

Nitrogen fixation, produces nodules on legume roots. Bacteroids from nodules can be X, Y, and club shapes.

Produces streptomycin. Branching mycelium and coenocytic hyphae.
