Study on Selection of Bacillus Sp. Strain Has Active Carbon Metabolism for Peat Treatment

The objective of selecting strains Bacillus sp. has high activity in carbon metabolism for peat treatment, firstly focusing on the ability to degrade lignin, cellulose, phosphorus and protein. From gene pool, by surveying microbial capable degrading carbon-rich substrates including insoluble phosphate, proteolytic, we have identified two contain polyfermenticus subtilis strong metabolize decompose peat. strain had organophosphorus starch-degrading ring diameters 41, 40, 23 38 mm, respectively. 24 29 In addition, content humic acids formed after 48 hours fermentation increased 2.5 times compared original without addition 2.8 strain. Therefore, selected with efficiency producing acid products. At same time, a biosafety level (level 1, safest scale).
