NOVELTY - Preparing sold strain involves selecting disease-free and molds-free pepper stems and leaves. The selected pepper stems and leaves are dried to obtain moisture content of less than 10%, and then crushed to 100-120 meshes. Effective Microorganisms (RTM: mixture of beneficial bacteria and yeast) (EM) liquid bacteria is selected having effective viable number i.e. greater than or equal to 5x 100cells/ml. The crushed pepper mixture (1000kg), water (900-1000kg), brown sugar (50kg), EM liquid bacteria (6kg), potassium dihydrogen phosphate (3kg), peptone (1kg) and magnesium sulfate (600g) are weighed accurately.    USE - Method for preparing solid strain (claimed).    ADVANTAGE - The method enables to prepare eco-friendly solid strain.    DETAILED DESCRIPTION - Preparing sold strain involves selecting disease-free and molds-free pepper stems and leaves. The selected pepper stems and leaves are dried to obtain moisture content of less than 10%, and then crushed to 100-120 meshes. Effective Microorganisms (RTM: mixture of beneficial bacteria and yeast) (EM) liquid bacteria is selected having effective viable number i.e. greater than or equal to 5x 100cells/ml. The crushed pepper mixture (1000kg), water (900-1000kg), brown sugar (50kg), EM liquid bacteria (6kg), potassium dihydrogen phosphate (3kg), peptone (1kg) and magnesium sulfate (600g) are weighed accurately. The brown sugar, potassium dihydrogen phosphate, peptone and magnesium sulfate are added in clean and transparent container, and then mixed with water with stirring till complete dissolution. The obtained mixture is added with EM liquid bacteria, and then container is sealed for fermentation for 15-20 days. The obtained mixture is added with crushed pepper stems and leaves. The clean tile having 10-15 cm thickness is selected. The obtained mixture is poured on the selected tile at 20-25 degrees C having humidity 70-75 degrees for 3-5 days. The obtained mixture is dried at 50 degrees C to obtain moisture content below 8% to obtain sold strain. The obtained solid strain (100g) is packed in plastic bag, and sealed.
