Many microorganisms can produce intracellular and extracellular biopolymers, such as
polyhydroxyalkanoates (PHA). Despite PHA's benefits, their widespread at the industrial …

This review paper provides an overview of various types of photobioreactors (PBRs) that
could be used for the production of polyhydroxyalkanoates (PHAs) using anoxygenic …

Aquafeeds contain protein ingredients such as fishmeal and soybean meal, yet their
production puts pressure on the environment. Finding novel protein sources such as dried …
