摘要: 从3个日本沼虾(Macrobrachium nipponense)养殖池塘的水体、虾中分离得到41个菌株,经16S rDNA基因序列分析,结合菌落形态观察,水体分离到的菌株初步鉴定为芽孢杆菌属、气单胞菌属、肠杆菌属等,虾肝胰腺中分离的菌株初步鉴定为气单胞菌属、柠檬酸杆菌属、肠杆菌科等。采用滴注法检测了噬菌体NTHP01对分离到的细菌的抑菌效果,结果表明,噬菌体NTHP01对芽孢杆菌、气单胞菌、不动杆菌、肠杆菌、柠檬酸杆菌、原生节杆菌、邻单胞菌、格氏乳球菌等均具有较好的裂解作用。将噬菌体NTHP01制剂在日本沼虾养殖塘进行示范应用,初步结果表明日本沼虾产量提高338~412 kg/hm2,产值提高2.25万~3.00万元/hm2

Abstract: 41 bacterial strains were isolated from water and shrimps of three Macrobrachium nipponense ponds, by 16S rDNA gene sequence analysis and colony morphology observation, the strains from water were preliminarily identified as Bacillus megaterium, Aeromonas caviae, Enterobacter roggenkampii,et al, the strains from shrimp were preliminarily identified as Aeromonas caviae, Citrobacter murliniae, Enterobacter roggenkampii, et al. The phage NTHP01 inhibition of bacteria was detected by drop injection methodthe results showed that, phage NTHP01 had good cracking effect on Bacillus, Aeromonas, Acinetobacter, Enterobacter, Citrobacter, Arthrobacter protophormiae, Orthomonad, Lactococcus garvieae, et al. Phage NTHP01 preparation was appliled in shrimp breeding pond, the preliminary results showed that, the yield of Macrobrachium nipponense increased by 338~412 kg/hm2, and the output value increased by 2.25 ten thousand ~3.00 ten thousand yuan/hm2.
