This is a high-purity live bacteria, allowing you to experiment with a single culture under various environmental conditions. This bacteria is Gram- and spiral shaped. Rhodospirillum rubrum is photosynthetic and grows anaerobically in sunlight and aerobically in the dark.
Each culture comes in a test tube on agar media. These slant cultures are made with 5ml of agar that is rotated diagonally to provide the maximum surface area for the bacteria culture growth. The culture can be transferred with an inoculating needle. Each culture provides sufficient bacteria to streak 10-15 petri dishes, enough for a classroom of 30 students.
Live cultures can be difficult to sustain. The culture will come with care instructions, but plan to use it within 1-2 days of arrival for best results. This item cannot be returned.
