There are concerns regarding the safety of this fungicide. 22. Bacillus subtilis is a Gram-positive, rod-shaped bacterium that is the type species of the genus Bacillus, commonly used as a model organism to describe the structure of different species of the genus. Arshine Questions and Answers about Bacillus Licheniformis.docx . Colonies are both round and irregular in shape, with irregular (undulate, fimbriate) margins. (Bryan MacDonald, Christopher Adams, and Kyle Smith, Brigham Young University, Provo, UT), Figure 7: Serratia marcescens morphology (Enlarged view). 42. B. licheniformis has proved itself as a multipurpose organism and has gained popularity along with B. subtilis.
