Gigaspora albida -- preparing clean healthy spores for shipment
 |
Heavily parasitized spores. These spores are so thoroughly colonized that they are uniformly black. Several of these spores in a population from which DNA is extracted will introduce considerable contamination. On the bright side, these parasitized spores are easy to detect and remove. When we find a culture in this state, we go through at least two propagation cycles using only washed spores as inoculum | |

Cleaned healthy spores. In the population at left, 98% of the spores are mature and healthy, with stable uniform contents and no signs of deformity, degradation, or parasitism after storage in a refrigerator for at least 48 hrs. Also included in this photo (because they don't harm the prep) are healthy immature spores. They are evident by denser contents that are white to salmon pink in color. |
