The aim of this mini-review with own results was an identification of techniques to suppress the growth of microbial contaminants under photo- and mixotrophic conditions. Techniques identified are the modification of environmental conditions, such as pH, oxygen, and nutrient concentrations, as well as the application of pulsed electric field, ultrasonication, and surfactants. In phototrophic cultivations, the mentioned techniques result in a decrease of number of predatory cells, but not in a complete removal. Measures to suppress the growth of contaminations (e.g., bacteria and fungi) in mixotrophic cultivations could not be identified. The co-cultivation of algae and fungi, however, was found to be beneficial for the utilization of unusual carbon compounds (e.g., phenolic compounds).

这项带有自己结果的小型审查的目的是确定在光养和混养条件下抑制微生物污染物生长的技术。确定的技术是环境条件的改变，例如 pH 值、氧气和营养浓度，以及脉冲电场、超声波和表面活性剂的应用。在光养培养中，上述技术会导致捕食性细胞数量减少，但不会完全去除。无法确定在混合营养培养中抑制污染物（例如细菌和真菌）生长的措施。然而，发现藻类和真菌的共培养有利于利用不寻常的碳化合物（例如酚类化合物）。
