Recirculatory Aquaculture System (RAS)
Introduction: Recirculation Aquaculture System (RAS) is a generation in which water is recycled and reused after filtration and elimination of suspended rely and metabolites. The approach is used for highdensity lifestyle of diverse species of fish utilising minimal land place and water. It is an in depth approach (better densities and greater rigorous management) than different aquaculture ...

Derisking Scale-Up
How to de-risk the scale-up process? We’ve all been there as a researcher or biotech professional. The strain of algae culture or microbes we are growing in our lab is thriving. It seems so straightforward and simple to culture, we believe we have it figured out. We easily create replicates in the lab at bench scale. We are now ready for the true test: scale-up time! Will this results we ...

Photobioreactors: Advantages & Disadvantages
What are open and closed algae culture systems? The two broadest methods of culturing algae at medium to large scale are split into two styles of system: open and closed photobioreactors (PBRs). A PBR is any device or system that supports the culture of photosynthetic organisms using light. There are photobioreactor advantages and disadvantages to both types systems depending on the goals you ...

Combined yeast and microalgal cultivation in a pilot-scale raceway pond for urban wastewater treatment and potential biodiesel production
A mixed culture of oleaginous yeast Lipomyces starkeyi and wastewater native microalgae (mostly Scenedesmus sp. and Chlorella sp.) was performed to enhance lipid and biomass production from urban wastewaters. A 400 L raceway pond, operating outdoors, was designed and used for biomass cultivation. Microalgae and yeast were inoculated into the cultivation pond with a 2:1 inoculum ratio. Their ...

Cultivation of an Arthrospira platensis with digested piggery wastewater
An Arthrospira platensis strain ZJWST-S1 was isolated in Jiaxing City, China, which proved able to proliferate quickly in undiluted digested piggery wastewater (DPW), and the protein content in the algal biomass was high. Single factor experiments showed that the strain was able to quickly grow in a Zarrouk medium as the dosage of sodium bicarbonate, nitrate-nitrogen and phosphate-phosphorus ...
