Handling of the strain
- received Brevibacillus parabrevis ATCC 8185 from Marahiel lab
- plate stood 1 week at RT in Marburg => wet, stinks
- plate cells on LB, inoculate 2x YT medium
- scratch everything from plate, centrifuge, wash with H2O, centrifuge, resuspend in H2O
Result
Three bands were visible in the UV-chamber. The three respective lanes implicate a fragment size of 1.5kb, 1.5kb and 1.2kb. This matches well the expected sizes. Therefore we can conclude that our colony PCRs have been successful!

Evaluation of the strain
Result
Colonies grew over night -> as colony PCRs were positive and the strain was cultivatable, the plate of marburg seemed to be intact (despite long storage under bad conditions).
