泡菜中对铅有高吸附性的乳酸菌的分离鉴定及特性研究
Isolation,identification and characteriation of lactic acid bacteria with high adsorption to lead in pickles
摘要
Abstract
Lead-resistant and adsorptivity lactic acid bacteria were screened out from pickles and used for the removal of heavy metal lead.Four strains were isolated from the samples by spread plate method,and lead resistant reached 2000 mg/L,when the concentration of lead was 100 mg/L,,the adsorption rate of p3 was highest,reached 78.90％.The results of morphology observation,physiological and biochemical identification and mass spectrometry detection and 16S ribosomal deoxyribonucleic acid sequencing data showed that p3 could be identified as Lactobacillus brevis.The strain grew well in the salt containing 0～5％,and it was able to tolerate the hydrochloric acid with pH value of 2,the salts of 8.0 g/L and trypsin of 1.1 g/L.It can be used to treat waste water,make pickles orreduce lead levels in animals as a probiotic in the future.关键词
