What is Effective Microorganisms (EM1)

After my first two posts about bokashi and EM1 I had someone ask me “What is Effective Microorganisms?” I realized I did a really poor job of explaining EM1 previously (sorry!)

Effective Microorganisms or EM1 as discovered in the early 1980’s are a combination of 3 facultative  microbes.  The benefits and some uses of EM1 were covered in my previous article the microbes that EM1 contain are:

  • lactic acid bacteria
  • yeasts
  • purple non-sulphur bacteria

Lactic acid bacteria are well known, they’re used to make yogurt, cheese, kefir and other fermented foods.

yeasts are also well known, they’re used to make beer, wine, liquor and cause bread to rise.

Purple non-sulphur bacteria (PNSB) are the least known of the 3 ingredients. PNSB are commonly found in sediment in ponds, lakes and swamps below shallow, slow moving water. PNSB are phototropic or photosynthetic bacteria. Their purposes in EM1 is mostly in benefiting plants in the garden. PNSB are nitrogen fixing microorganisms and provide food for other soil microbes. They also provide some decomposition of potential toxins that may exist in the environment or fermentation process. To get original EM1 for gardening and agricultural usage click here
