Cutting Algae Costs
Algae are not new in the aquaculture sector. In fact, algae are in many cases indispensable for the success of the aquaculture industry. The biggest hurdles for inhouse algae production in the aquaculture industry are the high costs, the labour intensiveness, and the complexity of maintaining healthy algae cultures. Traditionally, hatcheries have been using big plastic bag type systems and bubble ...

National Algae Association’s 2018 Algae Year in Review
The general public, taxpayers, and the business and investment communities continue to ask about the algae product claims made by university algae researchers, lobbyists, DOE Algae Biomass/BETO and market research studies. They have been promoting potential algae products since the first algae study conducted by Carnegie Mellon 75 years ago, and we’re now asking, with no response, where the ...

Algae research budget cuts... what now?
Other than long overdue massive budget cuts, nothing has changed at the Department of Energy Algae Program. NAA has asked the DOE Secretary to review algae technologies giving private industry the opportunity to see if any algae technologies could be used in commercial algae production. While the DOE conducts advanced algal systems listening sessions, commercial algae producers are in commercial ...

Industrial Plankton, the Victoria Company Working With Algae
Industrial Plankton’s photobioreactors make business easier for companies around the world. And they are located in Victoria! Using traditional methods, algae production can be a difficult and error-prone process. “We found out that everybody in aquaculture was having trouble growing algae, and they were doing it with old-school methodologies,” says Robert Roulston, CEO of ...

Alternative Products from Algae
Algae Biomass Summit 2020 discussed Alternative Products from Algae. This session was moderated by Lieve Laurens, National Renewable Energy Laboratory. Dr. Laurens opened with the introduction: What makes algae so remarkable? One aspect would be the creativity of the algae community to identify novel algae products, especially when it comes to product commercialization. Some of the credit ...

DOE-Funded Algae Foundation Education Initiative Announced
On October 2, 2015, at the 2015 Algae Biomass Organization Summit, the Algae Foundation announced a U.S. Department of Energy (DOE) funded education initiative to enhance algae workforce development. The Algae Foundation is a non-profit organization committed to expanding the algae industry though research, education, and outreach, and plays an important part in advancing the bioeconomy beyond ...

Bioreactors for Algae Seed Train Inoculum to Maximize Production in Massive Systems
The Drive Towards Scalable and Efficient Algae Production Producing algae as a commodity for feed, pharmaceuticals, nutraceuticals, carotenoids, and pigments calls for expansive setups. Executing this production at scale and making this economical, vast installations like raceway ponds or extensive tubular systems are required. However, the efficiency of these systems hinges on a critical ...

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 ...

Qualitative algal analysis from the fish-gut: Tested in the rice fish cropping system
Abstract: Algae constitute a major proportion of fish food in rice-fish culture system. Study of algal preferences and their availability in the natural environment might be important for developing natural fish feed. Preparation of formulated feeds using under-exploited materials such as algae not only reduces production costs, but also increases procurement accessibility of locally available ...

Toxicity evaluation of two typical surfactants to Dunaliella bardawil, an environmentally tolerant alga
Sodium dodecyl benzene sulfonate (SDBS) and cetyl trimethyl ammonium chloride (CTAC) are two kinds of surfactants widely applied in various industries. The tremendous direct discharge of these surfactants into natural waters has posed a significant threat to ecosystems. Dunaliella bardawil was employed in the present research to test the toxic effects of SDBS, CTAC, and their mixture on cell ...

Conical Bottom Tanks-Backstory - Case Study
Originally we only offered the flat bottom tanks in our line of tanks. Eventually, fit was discovered that they are ideal for growing algae with natural sunlight, however some growers wanted to something a little more. Several customers wanted an easier way to harvest the algae from the growth chambers, particularly the bottom. Siphoning works for the flat bottom tanks, and is a great option for ...

Blue Lagoon Iceland - Case Study
We are delighted to announce the recent completion of two Phyco-Flow systems for the Blue Lagoon in Iceland. This development is the latest stage in a relationship dating back to 2004 when a BioFence system was installed to support work being undertaken within their R&D ...

Microalgae Growth - Light Spectrum
Microalgae need light to grow and photosynthesize, but not all light is created equal. The spectrum of light can have a big impact on how well your algae grows. The spectrum of a light is how bright it is at different wavelengths. This can be closely related to colour, e.g. a red LED looks red because it is emitting light with a wavelength of 650 nm. However, differences in light spectra can ...

Seaweed extract uses in agriculture
In recent years, the damage caused by the blind and excessive application of chemical fertilizers and pesticides has become more and more serious. To develop ecological agriculture, we must vigorously promote the use of biological fertilizers and pesticides. The abundant marine biological resources are a material treasure house for the development of ecological agriculture. Seaweed extracts is ...

Light Intensity
Microalgae Growth – Light Intensity If light is one of the key ingredients in photosynthesis, will more light always generate more productivity? Not exactly. Microalgae growth tends to have a consistent relationship with light intensity. Though the actual growth rates and intensities for different points in this curve will vary depending on many factors the general shape is consistent ...

Interest in DOE Algae Biomass Program/BETO technologies diminishes because they have proven to not be scalable outside the lab in demonstration or pilot tests.
After over 10 years of attempts at collaboration between the DOE Algae Biomass Program/BETO, university algae researchers and commercial algae producers over highly advertised pay-to-play taxpayer funded technologies, NAA and its algaepreneurs have no further interest. Why? On information and belief, many of these hyped technologies have not been able to be proven outside the lab in demo and ...

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 ...

Nickel effects on productivity of algal periphyton communities
In order to evaluate the long-term (30-day) influence of nickel on biomass of periphyton communities, indoor artificial streams were used with differing nickel concentration (2.5, 5, and 7.5 mg/l). Physical and chemical factors (pH, NO3-N, PO4-P, dissolved oxygen, total suspended solids, conductivity, total dissolved solids, biochemical oxygen demand, and chemical oxygen demand) were measured ...
