Discovery NotesSoil was collected from the North Dekalb Mall Community Garden at the outskirts of a vegetable patch in which squash and a few other crops were growing. Soil was rich and loamy, likely commercial agricultural soil.

Phage was initially isolated on an equal-parts mix of four different Arthrobacter strains (A. globiformis B-2979, A. pascens B-1814, A. globiformis B-4425, A. humicola B-24478). After initial purification, the phage was found to plaque only on A. pascens 1814 A and A. globiformis B-4425. Subsequent stages of purification were done only with A. pascens B-1814.

Prior to naming, this phage was designated “S11.2” throughout isolation and purification.

Isolated in the lab of Dr. Nic Vega.
Naming NotesIn Mesopotamian mythology, Humbaba is a monstrous figure who serves as the guardian of the Cedar Forest. He is best known for his appearance in the Epic of Gilgamesh, in which the titular character—Gilgamesh, king of Uruk—and his companion Enkidu travel to the Cedar Forest to slay Humbaba and achieve fame and renown. Having subdued the beast, Gilgamesh hesitates, but Enkidu convinces him to finish the job (and quickly, before the gods find out what's going on). In the aftermath of the killing the heroes desecrate the forest in a frenzied rampage. I name this phage in sadness for slain Humbaba and in hope that the natural world will find new guardians in this time of catastrophe.
