研究发现，分别从褐藻墨角藻（Fucus evanescens）和Chorda file 1中分离出的KMM 3296和KMM 3298菌株以及从刺参（Apostichopus japonicas）中分离出的菌株3297都能降解褐藻酸酯。这些菌株的岩藻糖酸酶在pH 6.5 ~ 7.0时能有效降解褐藻的岩藻糖聚糖，并在40 ~ 50℃时保持活性。岩藻糖聚糖的内型水解形成硫酸化的α - l -岩藻低聚糖。另外9株从其他生境分离的柠檬酸单胞菌（包括该菌株的型菌株）均不能降解褐藻多糖。
It was found that Pseudoalteromonas citrea strains KMM 3296 and KMM 3298 isolated from the brown algae Fucus evanescens and Chorda file 1, respectively, and strain 3297 isolated from the sea cucumber Apostichopus japonicas are able to degrade fucoidans. The fucoidanases of these strains efficiently degraded the fucoidan of brown algae at pH 6.5-7.0 and remained active at 40-50degrees C. The endo-type hydrolysis of fucoidan resulted in the formation of sulfated alpha-L-fucooligosaccharides. The other nine strains of P. citrea studied (including the type strain of this species), which were isolated from other habitats, were not able to degrade fucoidan.
