Abstract

In response to the problem of iron limitation in nitrogen-fixing cyanobacteria, this study explores the potential for symbiotic and mutually beneficial community survival of Polychaeta and Trichoderma. The presence of the two elements and their effects on the survival of the cyanobacteria were first analysed in the context of nitrogen and iron use and cycling in the ocean. The physiological characteristics of the two algae were also analysed in relation to environmental factors such as light, ph and temperature in the marine water column. 730The results of the incubation experiments showed that the filtrate of Trichoderma reesei had a significant effect on the growth of Polycoccus, with the OD730 rising to 0.0372 within 72 hours of the addition of Trichoderma reesei. The addition of the wild-type iron carrier secretion of G. globulus also promoted the growth rate and nitrogen fixation efficiency of the algae. The symbiotic relationship between the nitrogen and iron utilisation of the algae was shown to contribute to the growth and nitrogen fixation activities of both species.
海洋多肉和束毛藻的生理特征及氮和铁的利用
针对固氮蓝藻的铁限制问题,本研究探讨了多毛藻和木霉共生互利的群落生存潜力。这两种元素的存在及其对蓝藻生存的影响首先在海洋中氮和铁的使用和循环的背景下进行了分析。分析了两种藻类的生理特性与光照、ph值和海水温度等环境因素的关系。730培养实验结果表明,里氏木霉滤液对多球菌的生长有显著的影响,在加入里氏木霉的72小时内,OD730上升到0.0372。添加野生型球藻铁载体分泌物也促进了藻类的生长速度和固氮效率。藻类对氮和铁的利用之间的共生关系被证明有助于两种物种的生长和固氮活性。
