Abstract |
The bactericidal and algicidal properties of formalin, mercuric chloride, and Merthiolate were tested using grab river-water samples and cultures of Scenedesmus bijuga and Cyclotella meneghiniana. Formalin was bactericidal in plankton grab samples at a concentration of 1.0%. Cyclotella failed to grow in 0.01% formalin (the lowest concentration of formalin tested.) The growth of Scenedesmus was delayed briefly in 0.01% formalin, and completely arrested at a concentration of 0.1% or more of formalin. |
