A comparison of the bacterial microflora between coastal sites in Qingdao, P. R. China and Loch Fyne, Scotland

Aerobic, heterotrophic bacteria, recovered from two sites located on the west coast of Scotland, were compared to cultures obtained in a similar way from industrial, aquacultural and clean sites in the vicinity of Qingdao, Shandong, P. R. China. Gram-negative bacterial cultures were examined by BIOLOG-GN, and the data analysed by the simple matching (S_SM) and Jaccard coefficients (S_J) and unweighted average linkage clustering using NTSys. The output revealed that 20% of the bacteria, namely, Acinetobacter johnsonii, Aquaspirillum dispar, Pseudomonas spp. (two groups), Sphingobacterium sp., Vibrio, sp., V. campbellii, V. mimicus and V. hollisae, were common between the two geographical locations. However, the study revealed shortcomings with the BIOLOG-GN system for the study of coastal Gram-negative bacteria.
