When we think about global warming, we usually blame cars and factories for pumping out those heat-trapping gases. But what if we told you that little algae, the ones you find hanging out in lakes, also have a historical role in this climate tale? ...
Delicious shrimp cocktails, flavorful fish tacos, and nutritious seaweed salads – these ‘blue foods‘ are an essential part of our meals. Fished from our oceans and farmed in aquaculture settings, these aquatic delicacies form a significant cornerstone of global food consumption and the livelihoods of millions. However, the road to our plates is not all smooth sailing, ...
As algae-based research rises in prominence for its potential in renewable energy production and climate change mitigation, the need for high-precision analytical equipment is paramount. Hiden Analytical is excited to announce that the Hiden HPR-40 DSA (Dissolved Species Analyzer) is proving to be a perfect research tool in the rapidly evolving algae research landscape. The HPR-40 DSA is ...
Introduction In the era of climate change, understanding the shifting dynamics of marine ecosystems is paramount. With rising global temperatures, marine fish populations are responding by altering their spatial distributions, opening up a new frontier in marine biology research. For researchers probing this environmental enigma, the Hiden HPR-40 Dissolved Species Analyzer (DSA) offers an ...
This can sink blue-green algae and disrupt their life cycle, or affect the inner cell membrane of other types of algae, causing it to separate from the outer membrane. If you’re interested in learning more about using ultrasound to control algae growth in water treatment plants, check out the research paper “Ultrasound – A ...
An innovative field study in Southwest Florida has identified several neurotoxins in the state’s air and water. The three forms of BMAA – beta-Methylamino-L-alanine – are associated with brain diseases. The study conducted by Calusa Waterkeeper volunteers and analysed by Wyoming’s Brain Chemistry Labs identified two forms of BMAA in every sample from 945 completed over ...
Researchers find fish-killing algae thrive in light conditions associated with climate change A new University of Delaware study shows that changing light conditions associated with climate change will significantly increase the growth and impact of harmful algal blooms, creating powerful and persistent disruptions in the food web. The causes of harmful algal blooms may vary, but typically farm ...
Some harmful algal blooms (HABs) release toxins, causing illnesses in people, animals, and damaging the environment; New research links an algal toxin to neurological problems; People with liver disease are more prone to suffering from neurological problems caused by the blooms; HABs are more frequent and abundant. Learning which types are harmful and how to avoid contact with them is ...
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 ...
Abstract :Comparison is made between results of tests performed using the conventional algal growth inhibition test according to ISO 8692, in 250 ml Erlenmeyer flasks and based on laboratory algal cultures, with electronic counting of the algal cells (N), and those obtained with the Algaltoxkit-F™ tests using algal beads, long cells and Optical Density (OD) measurements. The exercise ...
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 ...
Many different algal types can bloom in a water body. Some of these algae are plant cells, while others are bacteria. Algae may vary in size, shape and cell characteristics. Typically, the type of algae that blooms depends on water temperature and sun hours. As a result, algal types may change several times during a season. To effectively control algae with ultrasound, it is important to know ...
Controlling algae with low-power ultrasound is a well-established technology that has been in existence for many years. It is an environmentally-friendly technology that is harmless to fish and plants. This article explains how ultrasound controls algae, including the five most common questions related to ultrasonic algae control. Algal blooms cause reduced light penetration, depletion of ...
The projects aim to generate high-impact tools and techniques for increasing the productivity of algae organisms and cultures and biology-focused breakthroughs. The project winners include: Lumen Bioscience, which will work with the National Renewable Energy Laboratory on the agricultural production of algae on otherwise non-productive land ...
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 ...
phosphorus pollution change the relationship between the pistillata and the algae living inside its tissues, a recent study has found. The researchers say the pollutants, mainly from urban and agricultural discharges, affect algae photosynthesis and the essential transfer of carbon from algae to the coral. Nitrogen and phosphorus pollution ...
Department of Energy (DOE) announced $18 million in funding for six projects to develop bioproducts and biofuels from algae. The funding is intended to reduce the cost of algae-based biofuels to less than $5 per gasoline gallon equivalent (gge) by 2019 to help reach DOE's target of $3 per gge for advanced algal biofuels by 2030. The projects that were selected ...
Predicting metal availability and toxicity for chronic (several hours or days) metal exposure scenarios, even for unicellular algae, is a major challenge to existing toxicity models. This is because several factors affecting metal uptake/toxicity, such as the release of metalbinding exudates, changes in the kinetics of metal uptake/toxicity over time and algal physiological ...
Previous studies have demonstrated the potential for impacts to the salamander embryo when growth of the algae is impaired by exposure to herbicides. To further investigate this relationship, we characterized the response of the symbiotic algae (Oophila sp.) alone to the PSII inhibitor atrazine under controlled laboratory conditions. Following ...
Pulse Amplitude Modulation (PAM) fluorometry, based on chlorophyll a fluorescence, is a frequently used technique in algal bioassays to assess toxicity of single compounds or complex field samples. It is known that several test conditions can influence the test results and since a standardized test protocol is currently lacking, it is difficult to link the results of different studies. ...
