Information processing
Each minesweeper square in the computer game corresponds to a bacterial colony on the agar mine-field. We have two bacterial strains: 1. the mine strain with the sender cells and 2. the non-mine strain with the receiver cells. The cells communicate through diffusion of OHHL and change color to give the player information in order to logically carry out the next move in the game. The colonies remain white as seen on the agar plate until any substrate is added. The left and the right click of the mouse is simulated with the addition of the multi-substrate mix and the single substrate.
The biology is explained here. The sender colony secretes the quorum sensing molecule 3-oxo-N-hexanoyl-L-homoserine lactone (OHHL) that diffuses through the agar to the surrounding cells. The receiver cells passively take up the OHHL by diffusion where the signaling molecule forms a complex with the inactive LuxR to activate it. The information is translated via mutated pLuxR promoters of different OHHL affinities which leads to the secretion of different hydrolases. Within minutes after the addition of substrate a change in color indicates the identity of the played colony and number of surrounding mine colonies.
