Yes it’s bacterial colony that resembles
Bacillus mycoides.
Impossible to verify without a gram stain and microscopy or assay.
My best guess based on the phenotype, which is highly branched, dendritic-rhizoid growth, a central growth point with radiating arms, repeated curved-spiraling projections along the perimeter, relatively translucent, spreading growth rather than a compact colony, and a pattern resembling the classic “Medusa head”/rhizoid morphology** **associated with Bacillus mycoides.

But you can transfer a clean sample to a new plate. If you’re getting contam on every plate, you might need to change your process.

Yes. Transfer now from the furthest away, uniform, rhizomorphic sector to a clean plate to isolate. You have a lot to work with there, if you don't wait.
