摘要
微藻生物质的生产和生产力管理在全球生物技术领域发挥着重要作用。本研究旨在研究 C. vulgaris 的生长动力学特征，对生物质生产进行经济分析，并建立一个简单的优化模型来选择最佳的栽培制度。结果表明，额外的二氧化碳供应可使 C. vulgaris 的特定生长率提高 35%，生产率提高 47%。对微藻类批量生长曲线的分析表明，潜在的有效培养周期分别为 2 天、4 天和 6 天。经济分析表明，两天的培养周期可获得最大的生物质产量。根据生物质产量，计算了不同培养周期的生产成本、净收入和生产利润率。
Biotechnological and economic assessment of the productivity of Chlorella vulgaris IBSS-19 microalgae under different cultivation regimes
The production of microalgae biomass and the management of productivity plays an important role in global biotechnology. This research aimed to study the kinetic characteristics of C. vulgaris growth, conduct an economic analysis of biomass production, and develop a simple optimization model for choosing the optimal cultivation regime. The results showed that the additional CO2 supply increased the specific growth rate of C. vulgaris by 35 % and increased productivity by 47 %. Analysis of the batch growth curve of microalgae revealed potentially effective cultivation cycles, which were two, four, and six days. Economic analysis revealed that the greatest biomass yield can be obtained using a two-day cultivation period. Depending on the biomass yield, the cost of production, net income, and profitability of production were calculated according to the cultivation cycles.
