ELECTRON DONOR SUPPLY METHOD AND ELECTRON DONOR FEEDING DEVICE TO MICROBE, AND AQUATIC LIFE BREEDING AQUARIUM AND FILTRATION TANK USING THE ELECTRON DONOR FEEDING DEVICE

摘要

PROBLEM TO BE SOLVED: To enable making an occupying space of an apparatus compact even when making an area large of a part that slowly releases a material that functions as an electron donor that becomes an energy source of a microbe.SOLUTION: A belt-like bag 10 accommodating a belt-like container 4 in which a material 3 that is composed by a non-porous membrane 2 and functions as an electron donor that becomes an energy source of a microbe is charged in an inside is wound around a frame body 12 to prevent adherence of the bags 10 by using a spacer 13, and the material 3 that functions as an electron donor that becomes an energy source of a microbe is made to slowly release from the non-porous membrane 2.
