Production of phytoplankton (microalgae and cyanobacteria) in commercial raceway ponds and other systems is adversely impacted by phytoplankton pathogens, including bacteria, fungi and viruses. In addition, cultures are susceptible to productivity loss, or crash, through grazing by contaminating zooplankton such as protozoa, rotifers and copepods. Productivity loss and product contamination are also caused by otherwise innocuous invading phytoplankton that consume resources in competition with the species being cultured. This review is focused on phytoplankton competitors, pathogens and grazers of significance in commercial culture of microalgae and cyanobacteria. Detection and identification of these biological contaminants are discussed. Operational protocols for minimizing contamination, and methods of managing it, are discussed.
在商业跑道池塘及其他系统中，浮游植物（微藻和蓝细菌）的生产受到浮游植物病原体的不利影响，这些病原体包括细菌、真菌和病毒。此外，养殖还容易因诸如原生动物、轮虫和桡足类等污染性浮游动物的捕食而导致生产力损失或崩溃。生产力损失和产品污染也是由原本无害的入侵浮游植物造成的，这些浮游植物与养殖物种竞争资源。本综述聚焦于微藻和蓝细菌商业养殖中具有重要意义的浮游植物竞争者、病原体和捕食者。文中讨论了这些生物污染物的检测与鉴定方法。还讨论了将污染降至最低的操作方案及其管理方法。
