Describe the physical and chemical characteristics of the environment, using as many sections/subsections as you require. If it is appropriate, you can divide the physical and chemical attributes of the environment into separate sections. Look at other topics available in MicrobeWiki. Which involve processes similar to yours? Create links where relevant.

A Thin section of an X. nematophilus cell, showing outer membrane blebs on the surface of the cell and in the surrounding area. B Negatively stained outer membrane vesicles in X. nematophilus cells showing electron-dense substances enclosed within.


Xenorhabdus nematophilus is a bacterium that exists in a symbiotic relationship with nematodes, of the genus Steinernema. The interaction is specific to each species. The are found in soil environments. Introduce the habitat, its ecological significance, and the importance of microorganisms in this environment. (What processes do they carry out? What functions do they perform?) What microbial processes define this environment? Describe microbial processes that are important in this habitat, adding sections/subsections as needed. Look at other topics in MicrobeWiki. Are some of these processes already described? Create links where relevant.

What kind of microbes do we typically find in this environment? Or associated with important processes in this environment? Describe key groups of microbes that we find in this environment, and any special adaptations they may have evolved to survive in this environment. List examples of specific microbes that represent key groups or are associated with important processes found in this environment. Link to other MicrobeWiki pages where possible.

Are there important biological interactions that are important in this environment? Do these interactions influence microbial populations and their activities? How do these interactions influence other organisms? Describe biological interactions that might take place in this environment, using as many sections/subsections as you require. Look at other topics available in MicrobeWiki. Create links where relevant.
