The use of wastewater has been investigated to overcome the economic challenge involved with a production of microalgae-based biodiesel. In this study, to achieve economical biodiesel production along with effective wastewater treatment at the same time, anaerobically treated brewery wastewater (ABWW) was utilized as a low-cost nutrient source, in the cultivation of Chlorella protothecoides.

Calcium ion and trace metals play important roles in various metabolisms of photosynthetic organisms. In this study, simple methods were developed to extract calcium ion and micronutrients from oyster shell and common soil, and the prepared extracts were tested as a replacement of the corresponding chemicals that are essential for growth of microalgae. The oyster shell and soil were treated with ...... hiện toàn bộ
View on a mechanistic model of Chlorella vulgaris in incubated shake flasksBioprocess and Biosystems Engineering - Tập 45 - Trang 15-30 - 2021

Kinetic growth models are a useful tool for a better understanding of microalgal cultivation and for optimizing cultivation conditions. The evaluation of such models requires experimental data that is laborious to generate in bioreactor settings. The experimental shake flask setting used in this study allows to run 12 experiments at the same time, with 6 individual light intensities and light dura...... hiện toàn bộ
Process and molecular data of branched 1,3-β-D-glucans in comparison with XanthanBioprocess and Biosystems Engineering - Tập 5 - Trang 89-93 - 1990
U. Rau, R. -J. Müller, K. Cordes, J. Klein
Bioreactor cultivations were carried out with Schizophyllum commune and Xanthomonas campestris. Influence of process parameters and downstream processing on molecular data (molecular weight, intrinsic and shear viscosity) of the secreted exopolysaccharide are shown. Glucan formation of S. commune was enhanced by oxygen limitation. Depending on the type of agitator used, a maximum glucan formation ...... hiện toàn bộ
A preliminary study on the impact of exogenous A-Factor analogue 1,4-butyrolactone on stimulating bitespiramycin biosynthesisBioprocess and Biosystems Engineering - Tập 42 - Trang 1903-1913 - 2019
Xiaowei Gao, Yonghong Wang, Ju Chu
Bitespiramycin is composed of nine main acylated spiramycin components with isovaleryspiramycin as the major component. However, even with excellent therapeutic effects, its application and industrialization are restricted due to its low titer. In this study, the exogenous addition of A-Factor analogue 1,4-butyrolactone (1,4-BL) stimulated an improvement in bitespiramycin biological titer by 29% w...... hiện toàn bộ
