The object of this work was to carry out a kinetic study on the Candida tropicalis cell lysis and to obtain a kinetic model that would describe the inhibitory and lytic effects of phenol on the yeast growth. From the experiments, a model for the growth kinetic behavior of the yeast was evolved. The proposed model describes satisfactorily the inhibitory and lytic effects of phenol on yeast cultures. From the kinetic model constants, it was found that C. tropicalis showed high affinity and tolerance toward phenol. The overall growth yields decreased when the initial phenol concentration increased, and it may be due to an increased maintenance coefficient and to cell lysis.
这项工作的目的是对热带假丝酵母细胞裂解进行动力学研究，并获得一个动力学模型，该模型将描述苯酚对酵母生长的抑制和裂解作用。通过实验，得出了酵母生长动力学行为的模型。所提出的模型令人满意地描述了苯酚对酵母培养物的抑制和裂解作用。从动力学模型常数发现，热带假丝酵母对苯酚表现出高亲和力和耐受性。当初始苯酚浓度增加时，总体生长产量下降，这可能是由于维持系数增加和细胞裂解所致。
