- Abstract:
- ... Microalgae have gained significant importance in biotechnology development, providing valuable goods and services in multiple applications. Although there is a rising market for most of these applications, the incorporation and introduction of microalgae into new venues will extend in the near future. These advances are due to the vast biodiversity of microalgal species, recent genetic engineering ...

- Abstract:
- ... It is known that microalgae respond to different light colors, but not at single-cell level. This work aimed to assess if different light colors could be used as triggers to sort over-producing cells. Six light spectra were used: red + green + blue (RGBL), blue (BL), red (RL), green (GL), blue + red (BRL) and blue + green (BGL). Fluorescence-activated cell sorting method was used to analyse single ...

- Abstract:
- ... Heavy metals in the effluents released from industrial establishments pose risks to the environment and society. Prevalent organisms such as microalgae in industrial wastes can thrive in this harmful environment. The connection of the metal-binding proteins of the microalgal cell wall to the metal ions of the heavy metals enables microalgae as an ideal medium for biosorption. The current literatur ...

To our knowledge, this is the first direct observation of feeding mechanism in this classical larval type. High‐speed video recordings showed that virtually all captures were mediated by large‐scale transient ciliary reversal over one or more portions of the main ciliary band correspon ...

As an alternative carbon supply approach in the microalgae cultivation process, bicarbonate shows many advantages over the conventional method of CO₂ sparging and may have great applicability in the future. However, the optimal bicarbonate concentrations for high biomass productivity and carbon utilization efficiency (CUE) are usually different, and a method to simultaneously achieve both of them ...

By capturing intracellular microcystins (MCs) release from microalgal cell destruction and extracellular MCs oxidation, this study suggests a mathematical model explaining the simultaneous removal of microalgae and their toxins (MC-LR, -RR, and -YR) in non-thermal plasma (NTP) application. Although the suggested model was built based on simplified kinetic assumptions, it can reasonably predict the ...
