In this paper, acidic hydrolysis (0–5 vol%) was performed on Chlorella vulgaris biomass using a range of temperature (100–130 °C) and reaction time (0–60 min) with high biomass load (10%–100 g L⁻¹), in order to characterize the kinetic of biomass solubilization, hydrolysis of sugars, proteins and ash release, and to verify the main divergences and similarities in relation to lignocellulosic biomass. More than 90% of the sugars present in the biomass was hydrolyzed and later satisfactorily fermented by S. cerevisiae. The inclusion of acid concentration in the kinetic model for biomass solubilization and sugar hydrolysis led to a modified Michaelis–Menten equation able to simulate efficiently the acidic extraction/hydrolysis data of all experimental runs. Main divergences in relation to lignocellulosics were related to higher reaction order and lower activation energy, reveling better susceptibility of microalgal biomass to acidic treatment. The proposed process is promising and can be easily scaled up at industrial level.

在本文中，对小球藻生物质进行了酸性水解（0–5 vol％），使用了一定温度范围（100–130°C）和反应时间（0–60 min），且生物质负荷较高（10％–100 g） L ^-1），以表征生物质增溶，糖，蛋白质水解和灰分释放的动力学，并验证与木质纤维素生物质有关的主要差异和相似性。生物质中存在的糖中超过90％都被水解，随后被酿酒酵母令人满意地发酵。。在生物质增溶和糖水解的动力学模型中加入了酸浓度，从而产生了一个经过修改的Michaelis-Menten方程，该方程能够有效地模拟所有实验运行的酸性提取/水解数据。与木质纤维素有关的主要分歧与更高的反应顺序和更低的活化能有关，表明微藻生物质对酸性处理的敏感性更高。所提出的方法是有希望的，并且可以容易地在工业规模上扩大规模。
