Abstract: A biodecomposable film material includes: a biodecomposable material which is one or more selected from the group consisting of polylactic acid, poly(butylene adipate-co-terephthalate) and poly butylene succinate and which has a mass percentage of 60-70%; a food grade agricultural waste having a diameter smaller than 50 ?m and a mass percentage of 10-30%; a modifier which is calcium carbonate powder or magnesium silicate salt powder and which has a diameter smaller than 8 ?m and a mass percentage of 7-29%; and an organic decomposing bacterium which is Bacillus amyloliquefaciens. The organic decomposing bacterium is heat resistant bacillus capable of withstanding a temperature of 100° C. and has a mass percentage of 1-3%. The biodecomposable material, the food grade agricultural waste, the modifier, and the organic decomposing bacterium are subjected to compounding and blowing to form a film having a thickness of 40-60 ?m.

Abstract: An isolated Bacillus amyloliquefaciens Ba-BPD1 having an Accession No. of DSM 21836 is provided. This novel strain has unique 16S ribosomal RNA sequenced as SEQ ID NO:1 and produces amylase, protease, cellulase and lipase, fibrinolytic enzyme to show their biodegradation capacities. Further, B. amyloliquefaciens Ba-BPD1 produces the antibiotic substances, such as iturin, fengycin and surfactin, and has antimicrobial capacity for inhibiting the fungal or bacterial growth. In conclusion, the novel strain of Bacillus amyloliquefaciens Ba-BPD1 and its products can be applied in agriculture, wastewater treatment, food industry and chemical industry.
