My group was assigned to write about Modestobacter sp. Colonies of Modestobacter are usually beige to pink in color, which correlateswith many of the strains we have plated. Colonies are alsocharacterized by an irregular shape and a shiny surface. However,when Modestobacter versicolor is plated on oligotrophic medium (meaning that is has very few components that are necessary tosustain life) the colonies appear dark brown to black as opposed tocopiotrophic medium which produces the pink colonies. Since wehave been using copiotrophic medium (I think), our colonies of Modestobacter should be beige-pink, irregularly shaped, and shiny. The picture below shows beige, shiny colonies with ragged edges; therefore, I believe it would be a Modestobacter sp.
