title: [Observation and comparison on microstructure of immobilized Aerobacillus fusiformis under wastewater treatment].
abstract: Aiming at printing ink wastewater, a strain of bacterium was isolated from activated sludge, and identified as Aerobacillus fusiformis. The Aerobacillus fusiformis was respectively immobilized in calcium alginate gel, polyvinyl alcohol (PVA) and microporous ceramics and their microstructure were observed by scanning electron microscope (SEM). It was found that calcium alginate gel might dissolve in the wastewater, and the activity was restricted as cells wrapped in PVA, so the COD removal ratio was low. The method of immobilized cells using microporous ceramics is simple and COD removal efficiency can be achieved. In addition, the immobilized bacterium could not be separated easily from the ceramics in the wastewater.
