Use of bacteria in biotech - e.g. as simple biobots, as bionano processing nodes, and more.
Bacterial neogens (microbial biobots) are easily and cheaply made by designing a biochemical reaction network that reacts in a suitable way to outside stimuli such as chemicals or light, and connecting it to various extra genes controlling the behaviour of the bacteria or the production of other chemicals. This way the bacteria can be made to perform quite elaborate tasks, and often several kinds of bacteria are used together. More complex applications require the use of bionano, symbiotic and viral wetware, and other exotic applications, some of which have been widely used since the interplanetary age, whilst others are more recent or limited in popularity
