Description:

”Given the right conditions, algae can double its volume overnight. Microalgae are the earth’s most productive plants –– 10 to 15 times more prolific in biomass than the fastest growing land plant exploited for biofuel production. While soy produces some 50 gallons of oil per acre per year; canola, 150 gallons; and palm, 650 gallons, algae can produce up to 15,000 gallons per acre per year. In addition, up to 50 percent (or more) of algae biomass (dry weight) is comprised of oil, whereas oil-palm trees—curr

As global demand rises and petroleum supplies diminish, countries are turning to algae for energy security.
In smaller countries, like Croatia, where oil demand is low, and emission standards are poor, algae biofuel has the potential to significantly reduce reliance on foreign oil.

Biodiesel from Microalgae


The oil from the algae can be used for any combustion process. An even wider range of use for algae oil is obtained by the transesterification to biodiesel. This biodiesel can be blended with fossil diesel or can be directly driven as pure biodiesel B100.

Biodiesel from microalgae has a comparable quality as rapeseed methyl ester and meets the standard EN 14214. At biodiesel production about 12% glycerin is produced as a by-product. This glycerin is a valuable resource for the production of algae in closed ponds, the heterotrophic processes. Thus, the entire algae oil can be used as fuel.

Fish Food


Algae provide a natural solution for the expanding fishing industry:

High-protein fish food
Replacement for existing fish meal production
Algae have nutrients of many young fishes available


The fishing industry recorded an annual growth of over 10% and, according to experts, will beat the global beef consumption in 2015.

The Technology developed by CCRES offers the opportunity to deliver part of the needed proteins for fish farming on the resulting algal biomass.
Protein for the food industry


The demand for high-quality protein for the food industry has been growing rapidly over the years.

The big growth opportunities are:

Weight control
Fitness and Sports Nutrition
Food supplements


The market volume in the protein sector is continously growing and at the rate of US $ 10.5B in 2010 and according to experts, will steadily increase to approx. $25B until 2030.

“There is intense interest in algal biofuels and bioproducts in this country and abroad, including in US,Australia, Chile, China, the European Union, Japan, Korea, New Zealand, and others,” says Branka Kalle, President of Council Croatian Center of Renewable Energy Sources (CCRES).

Advantages algae has over other sources may make it the world’s favored biofuel. Algae could potentially produce over 20 times more oil per acre than other terrestrial crops.Algae avoids many of the environmental challenges associated with conventional biofuels.Algae does not require arable land or potable water, which completely avoids competition with food resources.
“The Asia Pacific region has been culturing algae for food and pharmaceuticals for many centuries, and these countries are eager to use this knowledge base for the production of biofuels,”says Zeljko Serdar, President of CCRES.

Without sustained high prices at the pump, investment in algae will likely be driven by demand for other products. In the short term, the growth of the industry will come from governments and companies seeking to reduce their environmental impact through carbon collection.

The ability to selectively kill cancerous cell populations while leaving healthy cells unaffected is a key goal in anticancer therapeutics. The use of nanoporous silica-based materials as drug-delivery vehicles has recently proven successful, yet production of these materials requires costly and toxic chemicals. Here we use diatom microalgae-derived nanoporous biosilica to deliver chemotherapeutic drugs to cancer cells. The diatom Thalassiosira pseudonana is genetically engineered to display an IgG-binding domain of protein G on the biosilica surface, enabling attachment of cell-targeting antibodies. Neuroblastoma and B-lymphoma cells are selectively targeted and killed by biosilica displaying specific antibodies sorbed with drug-loaded nanoparticles. Treatment with the same biosilica leads to tumour growth regression in a subcutaneous mouse xenograft model of neuroblastoma. These data indicate that genetically engineered biosilica frustules may be used as versatile ‘backpacks’ for the targeted delivery of poorly water-soluble anticancer drugs to tumour sites. https://youtu.be/KEHdZzc6wsI
