Analysis of Triacylglycerol (TAG) Algae Lipid Productivity with FlowCam®

High production rates of traicylglycerol (TAG), a lipid produced in microalgae, is a desirable trait in microalgae selection and cultivation.  TAG is used in a variety of applications ranging from biodiesel production to omega-3 fatty acid supplements.  

In a study published in Biotechnology for Biofuels (Cabanelas et al., 2016), Chlorococcum littorale, a strain of microalgae with increased triacylglycerol (TAG) productivity, was identified and analyzed. The cellular properties of the strain were imaged, favorable sub-populations were isolated, and confirmed for increased TAG productivity.

Algae Viability Analysis with FlowCam®: Effect of Continuous Flow Electrocoagulation Flocculation

Large-scale, commercialized microalgae cultivation and harvesting processes which are used to produce algae-based biofuels are resource intensive.

  1. Microalgae are grown in highly-diluted solutions;
  2. High volumes of water are required;
  3. Processes to dewater algae during harvest consume a lot of energy.

Centrifugation, chemical coagulation, and electrocoagulation flocculation (ECF) using batch reactors are a few examples of existing harvest processes.  These methods require high energy input, large amounts of chemicals, and/or additional infrastructure such as settling tanks.

Early Detection of Predatory Grazers in Algae Cultures

Research suggests that microalgal-based biofuels offer a promising alternative to fossil fuels, providing environmental benefits and rapid production rates that could match the modern energy consumption of fossil fuels. However, large-scale algae cultivation, which is utilized in algae-based biofuel production, is susceptible to opportunistic algal crop predators, such as rotifers, which can quickly destroy a large algae population.  

Thus, there is a need to develop a method of early detection and quantification of these potential predatory grazers in algal cultures.

Rapid Algae Characterization Using Dynamic Imaging Particle Analysis

Algae offers the potential to serve as attractive, renewable sources for fuel, feeds, and other products such as plastics, chemical feed stocks, lubricants and fertilizers.  For this reason, interest in algae technology research continues to grow.  Algae are appealing as a potential source for these products for a number of reasons: they grow fast in relatively simple environments; have high yields per area needed to grow them; absorb carbon dioxide during growth while releasing oxygen; and, unlike some other biomass sources, do not compete with agriculture because they can be grown in areas not used for normal agricultural purposes.
