MAXIMUM SPECIFIC GROWTH RATE (max)OF SIX ALGAL SPECIES DETERMINED IN BATCH CULTURE

  • 摘要: 批量培养谷皮菱形藻、莱茵衣藻、粉核小球藻、斜生栅藻、羊角月牙藻和铜绿微囊藻等六种藻类,在对数生长期,逐日计数而确定比增长率最大值(mar),发现(mar)值出现的时间在各种藻类中不同。同时讨论了每种藻类的(mar)与营养物质、光强、温度和起始浓度之间的关系。铜绿微囊藻的(mar)在一定的总磷(TP)浓度范围内随Th浓度呈上升趋势。根据获得增长率最大值的条件,对它们在浮游植物群落中的生态位作了说明。
    Abstract: Six algae species,Nitzschia palea (Ku is.) W. Smith,Chlamydomonas reinhardii Dang,Chlorella pyrenoidosa Chick,Scenedesmus obliquus (Turp.) Kutz,Selenastrum capricornutum Printz and Microcystis aeruginosa Kuts,were culled on batch in different conditions. The maximum specific growth rate (max) of these algae were determined by calculating the specific growth fate each day with cell counting untill log-phase. the max values were different in each algal species. The effects of nutrient contents,light intensity,temperature and initial inoculurn density on max value of these algae were discussed. The max value of N.palea,S.obliquus and S. capricornutum are 1.33 0.09,2.11 0.04 and 2.270.25 respectively. The max increases gradually with total phorsphorus concentrstion in a certain range. By analysing and comparing the various conbination of conditions for max,it was supposed that the maximum specific growth rate could be used as an index of algal niche,and the likely niche of each algal species in the phytoplankton community was illustrated.
