Pseudomonas putida P67.2 and Pseudomonas flourescens P75 based microbial sensors for biochemical oxygen demand (BOD) measurements in phenolic wastewaters of oil shale business
Aquafeeds Biofloc and clear-water RAS units: a comparison This examine as opposed two sorts of indoor, shrimp society systems: obvious-drinking water RAS and biofloc devices. Clearwater RAS experienced the edge in water quality, but shrimp during the biofloc procedure had a higher feed conversion ratio.
This microbial metabolism produces an oxygen demand proportional to check here the quantity of organic compounds beneficial as foodstuff. Underneath some instances, microbial metabolism can take in dissolved oxygen speedier than atmospheric oxygen can dissolve into your h2o or the autotrophic Neighborhood (algae, cyanobacteria and macrophytes) can generate. Fish and aquatic insects could die when oxygen is depleted by microbial metabolism.[two]
