We have reported that Vibrio furnissii, a chitinivorous marine bacterium, expresses a complex apparatus for adhesion/deadhesion to chitin analogues (1). In the present studies, we show that this organism exhibits a chemotactic response (swarming) to chitin oligosaccharides at concentrations as low as 10 microM. In contrast, V. furnissii exhibits slight to no chemotaxis to other utilizable compounds (glycerol, lactate, amino acids), with the exception of L-glutamic acid. V. furnissii may lack the tar (aspartate) receptor of Escherichia coli.
我们曾报道过，弗尼斯弧菌是一种以几丁质为食的海洋细菌，它表达了一种用于黏附/脱离几丁质类似物的复杂机制（1）。在本研究中，我们发现该生物体对低至10微摩尔浓度的几丁质寡糖表现出趋化反应（群体游动）。相比之下，除L-谷氨酸外，弗尼斯弧菌对其他可利用化合物（甘油、乳酸、氨基酸）表现出轻微或无趋化性。弗尼斯弧菌可能缺乏大肠杆菌的tar（天冬氨酸）受体。
