Note – after writing this post I found out this project is no longer active, though it still has some useful information.
For those interested in what the US Government is doing in areas relating to microbiology, there is a useful site to check out called “The Microbe Project“. The goal of this project is was to “to maximize the opportunities offered by genome-enabled microbial science to benefit science and society, through coordinated interagency efforts to promote research, infrastructure development, education and outreach.” There is a lot of information there on different agencies and their past funding opportunities.
