Bacillus mycoides: a living and responsive medium

One of my favourite bacteria, Bacillus mycoides. A very common bacterial inhabitant of soil which has a unique mechanism of movement. It is able to travel over and assimilate various surfaces and environments, and as it does so it sends out these unique multicellular exploratory tendrils. These images document its responses to various environments. Amongst bacteria it is uniquely responsive to stress and it’s pattern of growth changes in response to this.
