Special Issue Information

Dear Colleagues,

Bioprocess engineering deals with the design and development of equipment and processes for the manufacturing of wide range of products from biological materials. Treatment of waste water is also included in this field. Bioprocess engineering connects mathematics, biology and industrial design, and consists of various spectrums like designing of bioreactors, study of fermentors. It also deals with studying various biotechnological processes used in industries for large scale production of biological products. Bioprocess engineering include the work of mechanical, electrical, and industrial engineers to apply principles of their disciplines to processes based on using living cells or sub-components of such cells. It is becoming an engineering and science discipline with extreme importance and enormous potential.

The most crucial industrial production units in biotechnology are bioreactors. Although the basic operating principle of bioreactors is elementary, a great deal of knowledge of bioreactors is required to ensure the quality, quantity, and economy of the products. In the last decades, we have witnessed intensive research and development, considering the bioreactors of various forms. Investigations in the field of mathematical modelling and control are incredibly important. Dynamic modelling of bioreactors is a challenging problem due to the complexity of cellular metabolisms. The main control objective is to maximize the total production of the desired product. The appropriate strategy for achieving the control objective depends on the bioreactor geometry, bioprocess source media, bioreactor operating mode, the availability of the online measurements, the selected control algorithm, and the accuracy of the dynamic bioreactor model.

It is, therefore, crucial that all employed in the field of bioprocess engineering have enough state-of-the-art knowledge and that they have access to the experiences gained by other engineers and scientists. These are the primary aims of this special issue: Engineers and academics who have discoveries transfer them to others.

The area of the special issue is vast. We expect contributions from the fields of:

  • bioreactor geometry design,
  • sensors and actuators for bioreactors,
  • theoretical and experimental (identification) modeling of bioprocesses in bioreactors,
  • monitoring and data processing for physical and chemical quantities in bioreactors,
  • bioreactor control systems with advanced control concepts
  • new structures and algorithms,
  • optimization of bioreactors.

The scaling of Raceway bioreactors was studied by geometric and mechanical similarity, with an order of magnitude of 1:10. The hydrodynamic parameters involved (flow velocity, hydrodynamic stress or shear stress, dimensionless numbers of Re, Fr, and Euler Power) at different stirring speeds (30, 35, 40, and 45 rpm) were determined. The study, carried out using low-density particle imaging velocimetry (PIV), showed that the speed of the liquid medium remains above 30 cm/s from 30 rpm, which ensures turbulence in the system. The flow velocity suffers a decrease of approximately 18%, at different angular velocities, with similar biomass concentrations (3.24 × 105–3.72 × 105 cells/mL). This decrease in speed directly affects the values of all the parameters involved in the bioreactor. Furthermore, the measurement of hydrodynamic stress (τ) indicates that the microorganisms are exposed to a value of 0.299 Pa at 35 rpm and 0.370 Pa at 40 rpm. Due to mechanical agitation, hydrodynamic stress values in Raceway systems have not been previously reported. The studies were carried out in a 10 L Raceway bioreactor using a consortium of microalgae and cyanobacteria where Spirulina sp. and Pseudanabaena sp. predominate. Full article
