Genus Serratia presents special problems of identification because of biochemical and morphological similarity to other genera of the Enterobacteriaceae, notably Klebsiella and Enterobacter. Serratia liquefaciens is an opportunistic pathogen which is capable of colonizing a wide variety of surfa... Read More

Micrasterias is a Desmid - a group of green algae mostly found in neutral to acidic fresh waters and sphagnum bogs. Most are unicellular, though a few form chain-like colonies. Each cell is constructed of 2 semicells which are mirror images of each other. In Micrasterias the cells are flattened ... Read More
