An improvement on bacterium cultivation led to yield over 75g of the dried and defatted cells (309g wet cells) from 6L culture medium containing 4% wt/v of D-glucose as a carbon source and 1 %wt/v of ammonium sulfate as a nitrogen source. The modified PCP method afforded 2.25g of LPS (3.0% yield from the cells) from 75g of the dried and defatted cells. It was confirmed that the obtained LPS showed in vitro an inactivation of bacteriophage φX174 from a plaque counting assay., バクテリオファージφⅩ174のレセプターとしての生理活性を有するリポ多糖を大腸菌C株の乾燥脱脂薗体から簡 便に大量調製する方法を確立した。培養条件を改良することによって炭素源としてグルコース4%wt/v,窒素源と して硫安1%wt/vを含む6Lの培養液から75gの乾燥脱脂菌体(湿菌体で309g)を得ることが出来た。得られた菌 体からPCP抽出改良法によってリポ多糖を抽出したところ,2.25gのリポ多糖が得られた(菌体重量の3.0%収率)。 得られたリポ多糖がバクテリオファージφⅩ174のレセプターとしての生理活性を有し,in vitroでのファージ不活 化能力を示すことがプラーク計数法で確認された。}, pages = {33--40}, title = {Simple Preparation of Large Amount of Lipopolysaccharide with Receptor Activity for Bacteriophage φXl74 from Escherichia coli C Strain}, volume = {15}, year = {1995} }
