Antimicrobial Activity of the Freshwater Bryozoan Hyalinella Punctata (Hancock, 1850)

Abstract

The antimicrobial activity of the freshwater bryozoan Hyalinella punctata (Hancock, 1850) was tested by microdilution method against eight bacteria and eight fungi for the first time. All five crude extracts (hexane, acetone, dimethyl sulfoxide, methanol and water) showed good antibacterial and antifungal potential in vitro wherein the acetone extract was the most active (MICs 0.50-7.00 mu g/ml and MBCs 2.50-10.00 mu g/ml).
