Line 32:
A population of bacteria in a closed system, also called ''biomass'', will grow according to a sigmoidal population curve (right), where growth rate is initially slow due to a small starting population, increases in rate as the population increases, and then slows again as the resources of the environment become too scarce to support such a large population. This last concept is known as the environment's ''carrying capacity (K)'', which is the maximum amount of bacterial biomass the system can support. In GT:NH, K is dictated by the size of the Vat's output hatch.
In order to keep the size of a growing population stable, bacterial biomass must be removed from the machine as fast as the bacteria are replicating. Therefore, to maximize the production of the Vat, the bacteria must be maintained at the population that gives the highest growth rate. This is illustrated on the curve, where the growth rate can be seen as the steepness of the slope of the curve. At a biomass of ½K, the curve is the steepest and so the rate at which the biomass can be drawn off without reducing the population is the highest. Mechanically, this manifests as the Vat gaining up to a 1000x bonus to production
=== Radiation ===
Line 38:
Some recipes require very specific different sievert levels. Instead of having to hunt for a different material for each of these recipes, a shutter can be closed to block some of the radiation to reach a more customizable value. Using a screwdriver on the radio hatch will open the radiation shutter interface, where up to 100 Sv of radiation can be blocked. Note that blocking radiation does NOT make the radioactive material last longer.
=== Usage Strategy ===
If any of the science for the Bacterial Vat went over your head, then this is the section for you:
* The recipe in NEI shows you the ratios of input fluid consumed to output fluid produced.
* For a 1:1 input/output fluid recipe ratio, the input hatch should be at most 1/2 of the output hatch's capacity
* Empty the output hatch to roughly half of its capacity. (You can use Fluid Detector covers for this.)
* The processing time is the same as depicted in NEI, before overclocking rules apply.
* The starter culture goes into the slot in the controller, the circuit goes into an input bus.
