Abstract

This study determined the range of conditionally normal values of the catalase activity (СA) in the Black Sea red macroalga Ceramium virgatum. The level of CА in the alga corresponded to its conditionally normal functioning (26.79 ± 10.32 μg H₂O₂/(g wet weight min)). The minimum concentrations of hydrochemical parameters that correspond to the sensitivity threshold of CА in C. virgatum were found; these minimum values are 40 μM/L for organic nitrogen, 0.03 μM/L for nitrites, 0.3 μM/L for nitrates, 0.12 μM/L for inorganic phosphorus, and 0.47 μM/L for organic phosphorus.

红海藻天竺葵罗斯的过氧化氢酶活性，以西南克里米亚海岸带为例，作为海洋环境质量的标志

摘要

本研究确定了黑海红巨藻天竺葵中过氧化氢酶活性的条件正常值范围（СA）。藻类中的CА含量与其条件正常功能相对应（26.79±10.32μgH ₂ O ₂ /（g湿重最小值））。找到了对应于C. virgatum中CА敏感性阈值的最小水化学参数浓度；这些最小值分别为：有机氮40μM/ L，亚硝酸盐0.03μM/ L，硝酸盐0.3μM/ L，无机磷0.12μM/ L和有机磷0.47μM/ L。
