Kitchen Gardeners International: Our buddy bacteria

Whether it’s lysteria in hot dogs, e.coli in ground beef or salmonella in peanut butter, bacteria is more often than not seen as one of the “bad guys” of the microscopic world. The result of this is that we are fast becoming a "bacterophobic" society.

If you have any doubts about this, just take a good look around you next time you go to the grocery store or pharmacy. A few years ago, only a few dozen products containing antibacterial agents were being marketed for the home. Now more than 700 are available. We're now being bombarded with ads for cleansers, soaps, toothbrushes, dishwashing detergents, and hand lotions, all containing antibacterial agents. Ironically, new research out of the University of Michigan suggests that not only are these anti-bacterial products no better than good 'ol soap and hot water, but that they could render some useful antibiotics less effective over time.

While bacteria has recently been cast in the bad guy role, organic gardeners know that bacteria do much of the behind-the-scenes, dirty work in the soil and in the compost pile. What a lot people don't know is just how critical this work is. Were it not for soil bacteria, there would be no kitchen garden. In fact, there'd be no life at all. We've posted a slideshow to our website (available as a PDF or a PowerPoint file) which explains how bacteria fit into the big picture called life.

If you're not a soil bacteria fan by the end of this blog post, then consider this one last fact: bacteria might even make you a happier person. Researchers at the University of Bristol in the UK have found that a common soil bacteria called "mycobacterium vaccae" could act like antidepressant drugs. This bacteria has been found to stimulate the immune system of mice and boost the production of serotonin, a mood-regulating brain chemical.

You always knew that gardening made you feel good. Now, perhaps you know why.
