Abstract

An antibiotic factor obtained from Alteromonas luteoviolacea was shown to kill Paramecium caudatum. This substance was shown to be destroyed by boiling, sonication, or freezing. It passed through a 0.45-micron-pore-size filter and was not precipitated from a culture supernatant with ethyl alcohol. Its production varied with A. luteoviolacea strains and medium constituents. It was also shown to be distinct from the A. luteoviolacea antibiotic that affects bacterial cells.

摘要

从紫色交替单胞菌中获得的一种抗生素因子被证明能杀死尾草履虫。该物质经煮沸、超声处理或冷冻后会被破坏。它能通过孔径为0.45微米的滤膜,且不会从培养上清液中被乙醇沉淀出来。其产量因紫色交替单胞菌菌株和培养基成分而异。它也被证明与影响细菌细胞的紫色交替单胞菌抗生素不同。
