mycofibrillin was originally a product designed by the space division of Molecular Architecture, ICC, under the Mycofibrillin™ trademark. It was a development of early experiments in creating spaceborne life, such as the regoformer “asteroid lichen”, which sustains itself using solar energy and water extracted from icy regolith.

Unlike its predecessors, mycofibrillin was designed not as an experiment or artwork, but as a functional tool. A designed-from-scratch neogen, it was a reinterpretation of various fungoid lifeforms – which took the form of an intertwined mat of fibers – for the space environment: a recreation of similar reaction networks making use of silicates, silanes, and silicones, at much lower temperatures, relying upon both a trickle of solar energy and provided radio-frequency energy broadcasts to power its metabolism.

The function of mycofibrillin was simply to stabilize aggregate-class “rubble pile” asteroids for relocation, or indeed for other exploitation. A rubble pile infected with a mycofibrillin culture, along with a microwave beacon to feed its growth phase, would swiftly find itself perfused by silicone-sheathed rhizomorphic hyphae of substantial tensile strength, acting to bind the many components of the rubble pile together into a single coherent mass.

Since this promising start, later offshoot technologies have included the thermophilic bionanotech weaves developed in conjunction with the chfsssc for stabilizing tectonically vulnerable regions of planetary crusts along with a variety of refined mycofibrillin derivatives, including a number of strains whose tensile strength is claimed to be suitable for maintaining the stability of large asteroids or small planetesimals when spun up to usable gravity-simulating speeds (although, in practice, the majority of residents of these worlds prefer microgravity environments).
