A [[photobioreactor]] (PBR) is a bioreactor which incorporates some type of light source (that may be natural sunlight or artificial illumination). Virtually any [[translucent]] container could be called a PBR, however the term is more commonly used to define a closed system, as opposed to an open [[storage tank]] or [[pond]].
Photobioreactors are used to grow small [[phototroph]]ic organisms such as [[cyanobacteria]], [[alga]]e, or [[moss]] plants.<ref>{{cite journal |last1=Decker |first1=Eva L. |last2=Reski |first2=Ralf |title=Current achievements in the production of complex biopharmaceuticals with moss bioreactors |journal=Bioprocess and Biosystems Engineering |date=14 August 2007 |volume=31 |issue=1 |pages=3–9 |doi=10.1007/s00449-007-0151-y |pmid=17701058 |s2cid=4673669 }}</ref> These organisms use light through [[photosynthesis]] as their [[energy]] source and do not require [[sugar]]s or [[lipid]]s as energy
source. Consequently, risk of [[contamination]] with other organisms like [[bacterium|bacteria]] or [[fungus|fungi]] is lower in photobioreactors when compared to bioreactors for [[heterotroph]] organisms.{{citation needed|date=October 2019}}
