异硫氰酸苄酯(BITC)防污损效果研究──对3种海洋细菌的抑菌作用

STUDIES ON THE ANTIFOULING EFFECT OF BENZYLISOTHIOCYANATE (BITC)- THE ANTIBIOTIC ACTIVITY OF BITC ON THREE MARINE BACTERIA

异硫氰酸苄酯（ＢＩＴＣ）的抑菌试验表明：ＢＩＴＣ对３种海洋细菌（假单胞菌Ｐｓｅｕｄｏｍｏｎａｓ ｓｐ． Ｔ１０８株、假单胞菌 Ｐｓｅｕｄｏｍｏｎａｓ ｓｐ． Ｅ２０４株和异单胞菌 Ａｌｔｅｒｍｏｎａｓ ｓｐ． Ｅ１１３株）的完全抑制 浓度分别为４． ０，１． ０和２． ０ ｍｇ／Ｌ，５０％抑制该３种海洋细菌生长（相对生长率）的浓度分别 为２． ６７，０． ３７和０．４４ ｍｇ／Ｌ。

The antibiotic activity of BITC on marine bacteria was tested. The BITC concentrations inhibiting 100 % growth of Pseudomonas sp. (T108), Pseudomonas sp. (E204) and Altermenas sp. (E113) were 4. 0 mg/L, 2. 0 mg/L and 1. 0 mg/L respectively. The concentrations inhibiting 50 % growth (relative growth rate) of these three bacteria were 2. 67 mg/L, 0. 37 mg/L and 0. 44 mg/L respectively.
