Bokashi bran is crucial for a fermentation process in Bokashi composters. Effective microorganisms found in the bran prevent a decay of biological waste and ensure the process without the unpleasant smell. The Bokashi bran contains beneficial microorganisms (lactic acid bacteria, yeasts, photosynthetic organisms, etc.), which start the fermentation process in Organko and prevent the decay of bio-waste. The effective microorganisms in the bran are extremely beneficial. Such microorganisms are also found in various types of food such as cheese, yogurts and wines. The bran prevents food from rotting. Besides, the bio-waste will remain in the correct condition, so it will retain all its energy and nutritional value.
