Abstract

Acinetobacter sp. utilized non-phenolic beta-o-4-model compounds, 2-methoxy-4-formylphenoxyacetic acid and veratrylglycerol-beta-guaiacyl ether (VGE) as sole carbon source. Vanillin, vanillic acid, protocatechuic acid and catechol were detected in the 2-methoxy-4-formylphenoxyacetic acid amended culture. Veratryl alcohol, veratraldehyde, veratric acid, vanillic acid, protocatechuic acid, catechol and guaiacol were identified from veratrylglycerol-beta-guaiacyl ether culture. Acinetobacter sp. produced catechol 1,2-dioxygenase and protocatechuate 3,4-dioxygenase that cleaved catechol and protocatechuic acid, respectively.

摘要

不动杆菌属利用非酚类β - o - 4模型化合物、2 - 甲氧基 - 4 - 甲酰基苯氧基乙酸和藜芦醇甘油 - β - 愈创木酚醚(VGE)作为唯一碳源。在添加了2 - 甲氧基 - 4 - 甲酰基苯氧基乙酸的培养物中检测到了香草醛、香草酸、原儿茶酸和儿茶酚。从藜芦醇甘油 - β - 愈创木酚醚培养物中鉴定出了藜芦醇、藜芦醛、藜芦酸、香草酸、原儿茶酸、儿茶酚和愈创木酚。不动杆菌属产生了分别裂解儿茶酚和原儿茶酸的儿茶酚1,2 - 双加氧酶和原儿茶酸3,4 - 双加氧酶。
