A practical guide to make Effective Microorganisms

Hi there!

Today I’ll write about making your own culture of EM (Effective Microorganism). We’ve wrote about EM in two previous articles:

In this guide I’ll elaborate the method a bit more, and show you a few photos.

In this moment I’m making EM cause I need them for two reasons:

  1. I need to clean the pipes of the kitchen sink in my house. Recently, the water start flowing down more slowly and I believe there is an accumulation of organic matter in the pipes.
  2. I’m experimenting with a small-size, balcony-type, earth-worm-powered compost, and I want to boost it regularly with EM like you would do on Bokashy Compost.

I’ll write down the instructions as well as my personal considerations and photos around the whole method here below:

  1. Take a handful of rice, let’s say 80-100 grams and put it in a container. Of course, you should use ecologic, integral and unprocessed rice for this purpose.

Notes: Workshop on Effective Micro-organisms

Hi !

I will post today this notes taken from a workshop I was participating a while ago, with some overview on the method to cultivate and use the Effective Micro-organisms (EM).

Effective micro-organisms

When we’re talking about effective micro-organisms (EM) we mostly mean a bunch of different species of micro-organisms with beneficial effects for processes in all natural environments. Effective Microorganisms consist of beneficial and non-pathogenic microorganisms such as Lactic Acid Bacteria, Yeast and Phototrophic Bacterias, which are found in many places in the nature: on our skin, in the water, in the air, in the food etc. By choosing certain kinds of micro-organisms and by increasing their amount in a certain place we can positively affect the environment in different ways.

What are the Effective Microorganisms (EM)?

Effective microorganisms (EM)
were developed in the early1980s at the University of the
Ryukyus in Okinawa, Japan by Professor Teruo Higa. He reported that a combination of approximately eighty different species of microorganisms are capable of positively influencing the decomposition of organic matter to the point at which it reverts to a ’life promoting’ process. These Effective Microorganisms consist of beneficial and non-pathogenic microorganisms such as Lactic Acid Bacteria, Yeast, and Phototrophic Bacteria, which are found in the natural environment.

Higa invoked the dominance principle to explain the effects
of his Effective Microorganisms. He claimed that three groups of microorganisms exist: positive microorganisms (regeneration), negative microorganisms (decomposition, degeneration), and neutral microorganisms. The ecological condition of any medium (that is soil, water, air, skin and intestinal) is hugely dependent on what type of microorganisms are dominant. The ratio of positive and negative microorganisms is critical, since the neutral, opportunist microorganisms follow the trend of regeneration or degeneration. Nowadays negative microorganisms (e.g. those responsible for the rotting of organic matter to maladies in organisms) dominate much of the sphere of the microorganisms in the environment. Treating the variety and massive volume of waste produced by societies and human activities has become an increasingly critical issue for humankind and the global environment.

Higa claimed that it is possible to favorably influence the given media by supplementing it with positive microorganisms. In short, it is possible to change the diversity of microorganisms so as to make effective microorganisms dominant.
