- Abstract:
- ... BACKGROUND: Tubular Photobioreactors (PBR) present better productivity using static mixers but they consume large amounts of energy. In this study, a tubular PBR is presented with a new static mixer that produces swirl mixing, inducing light–dark (LD) cycles, and adequate uptake of nutrients in the culture. This study was focused on diminishing the pumping energy required for culture transport whi ...

- Abstract:
- ... Algal growth is often inhibited in full-strength anaerobic digestate. The objective of this study was to investigate conditions under which digestate pretreatment using bacteria is effective in promoting algal growth, nutrient removal, and favorable changes in algal biomass composition. Batch culture experiments were carried out using low- and high-strength municipal sludge anaerobic digestate, tw ...

- Abstract:
- ... Poterioochromonas malhamensis is a flagellate grazer that readily contaminates Chlorella cultures and can have a devastating impact on them, especially in large-scale culture. Here, we developed a quantitative real-time polymerase chain reaction (qPCR) method to detect and quantify P. malhamensis from high-density Chlorella cultures. A set of primers specific to the mitochondrial cytochrome oxidas ...

A pyruvate-requiring marine bacterium, Pyruvatibacter mobilis CGMCC 1.15125ᵀ (=KCTC 42509ᵀ), was isolated from the culture broth of a photosynthetic marine microalga. Here we report the complete genome sequence of Pyruvatibacter mobilis, which contained a circul ...

The Droop model equations have been modified to deal with issues pertaining to light distribution and nitrogen uptake. In this paper, a singularity analysis of the steady-state Droop model equations and its modifications i ...

The blades of the wild-type strain (WT-10) of Pyropia haitanensis were irradiated with ultraviolet ray and treated with heat stress, and then a heat-resistant strain (SW-81) with high yield was isolated. Ultraviolet ray has a good effect on mutagenesis of tender blades of P. haitanensis, when the irradiation dose increased from 0 to 600 μW•min/cm², the frequency of the color-mutated cell-clusters ...

Anaerobic digestion has been identified as a promising technology for the treatment of food waste as it generates a significant amount of energy and can remove a substantial portion of the organics. However, this process has not been adequately a ...

Nitrogen pollution is of great concern, with nitrogen oxide (NOx) in the air and ammonia nitrogen in water being two major pollutants. Culturing microalgae in NOx or wastewater with high concentrations of ammonia nitrogen would both reduce environmental pollution and provide a source of nitrogen for microalgal culture. Ho ...

BACKGROUND: Over 90% of microalgae cultivations on a commercial scale are grown in outdoor systems, which means that the performance of these bioprocesses is dependent on the climatic conditions in each particular locality. Thus, the selection of suitable locations according to their climatic conditions is extremely important to develop technically and economically viable processes. This study aim ...
