Bioreactors

Bioreactors are an important technology, used in a wide variety of applications.  A bioreactor is essentially a self-contained habitat for microorganisms, feeding watering and sheltering them so they can perform some useful function.  Depending on the application, a bioreactor can be small enough to fit in a handheld device or large enough to fill a room. 

Depending on the organism and the nutrients fed into the bioreactor, it can do a number of useful things.  Bioreactors with specially engineered organisms can produce medicine, food, fuel, bio-plastics, and even building materials.   Bioreactors are used in the process of algal symbiosis.  Terra-forming operations also use this technology extensively, particularly in atmospheric conditioners and soil processors.

In space colonies, and on ships bioreactors growing algae recycle the air and water.  Many an astronaut has complained about the flavorless organic mush produced by a bioreactor for food when more appealing fare is in short supply.

Both Human and Cielioid -based civilizations make extensive use of this technology, as it is one of the gateway developments to serious space-fairing. One of the main manufacturers of bioreactors in human-controlled space is Cosmid, inc. one of the largest of the corporate states.  On Earth, bioreactors were first developed late in Era-0.

Soil Processors

Description

Soil processors are terraforming tools used to make regolith or alien soil amenable to agriculture.  Usually built into a mobile platform, such as a large truck, and paired with earth moving equipment, soil processors go from site to site, producing usable soil.  Some soil processors are stationary production plants, but these are the exceptions to the rule.

The first stage of the soil processor consists of a rock crusher that breaks stones into small enough pieces for the process to continue.  The second stage of soil processing sends the soil through a tumbler with microbial cultures added.  This stage takes the edges off of sharp-edged fragments, aerates the soil, and starts the growth of beneficial microbes.  After the tumbler, the soil spends a certain amount of time fermenting in a bioreactor, where it is stirred together with engineered algae, fungi and other living agents, such as worms and insects.  After the bioreactor is done, the soil goes through one more aeration stage before being returned to the ground.  

The whole process can take between a week and several months depending on what kind of soil is being processed, and for what use.
