strain of yeast that can easily break down red seaweed into biofuel. The
new development could help small island nations and other sea-bound
regions grow biofuel crops without giving up scarce land resources that
are needed to grow food. But it also opens up some challenges down the
road as human use of the marine environment increases.
is macro-algae and has the basic advantages of algae-fuels such as the
relative absence of hard fibers that are difficult to break down into
sugars. Seaweeds that come under the marine biomass category, degrades
much more easily than land crops, but there is still a catch. When red
seaweed is broken down it yields both glucose and galactose (a less
“sweet” form of sugar), and until now it has been difficult to find an
efficient fermentation process for galactose. The University of Illinois
team identified three genes in a common microbe, Saccharomyces
cerevisiae, that can be pumped up to increase galactose fermentation by

Algae-based waste-water treatment
Algae play a major role in aerobic treatment of waste in the secondary treatment process. Algae - based municipal wastewater treatment systems are mainly used for nutrient removal (removal of nitrogen and phosphorous). Algae have the ability to accumulate the heavy metals and thereby remove toxic compounds from the wastewater. In some cases, algae also play a role in the removal of pathogens in the tertiary treatment stage.
Major challenge in waste-water treatment
In waste water remediation using , aeration is a factor which requires a lot of attention. It is necessary to prevent sedimentation of the algae, to ensure that all cells of the population are equally exposed to the light and nutrients, to avoid thermal stratification and to improve gas exchange between the culture medium and the air
It has been proven that mixing the microalgal culture had a strong effect on the algal growth. Vigorous mixing increased the flashing light effect, removed excess dissolved oxygen, effectively improved the CO2 supply, and resulted in higher productivity (Laws et al., 1983; Richmond & Vonshak, 1978).
However, from the economic point of view, a high aeration rate will lead to higher running costs since mixing requires energy, so that it is not recommended for the large-scale production of microalgae.
THE GLOBAL PROBLEM:
Whenever you hear about rivers or seas that get polluted due to untreated sewage seeping in from maintenance or installation activities in wastewater treatment plants, that's because they don't have Mapal technology (see below for details)," states Fisher, vice president of Mapal Green Energy. "Every time they have to make a repair or want to upgrade to a fine bubble aeration system, they have to drain the whole reactor. This is a global problem."-*
A Simple device for Bioremediation
A company by name, Mapal Green Energy claims that it offers a simple device that offers a cheap device for bioremediation. This is a delicate process that has to be maintained properly and monitored constantly," Zeev Fisher, vice president for international business development of Mapal Green Energy tells ISRAEL21c. The air has to be added in just the right quantity, distributed evenly, and mixed well.
About three years ago, Fisher learned that a retired water company engineer had invented floating diffusers for fine bubble aeration systems. Realizing this would make it possible for the system to operate in any sort of reactor, he partnered with the inventor Hanoch Magen to co-found Mapal in 2008 with the financial assistance of investor David Azouri, now CEO.
Mapal's internationally patented CNM units are now installed in more than 20 wastewater treatment sites in Israel and in several other countries. The CNMs can be utilized in two types of municipal and industrial wastewater treatment facilities: Excavated biological reactor ponds and lagoons where fine bubble aeration was not possible before; and larger biological reactors ready for upgrading from the energy-intensive mechanical surface aerators.
A major bonus is that the CNMs can be installed in either type of facility without any need to drain the reactor or stop its operation. The "live and wet" installation process does not disturb the bacteria at work.
The Mapal system delivers energy savings of up to 70 percent compared to surface aerators. With no moving parts in the water, no maintenance is required; and pipes facilitate high-efficiency oxygen transfer to the bottom of the reactor.
Because of its straightforward design and operation, CNMs are ideal for rural areas lacking sophisticated technical capabilities. Based in Nesher, near Haifa, Mapal provides full process design and support, from feasibility studies and installation through training and financing. Each client receives a tailor-made solution, says Fisher.
As a result of efforts over the past year to increase its international marketing capabilities, Mapal just finished its second round of investments with an infusion of 1.5 million pounds from a British source. Over the next six months, Fisher reports, Mapal expects to sign two or three major contracts in the global market.
Beckons Industries is a reverse merged company and thought to be a stock market play, till recently.
Some of the announcements made by the company appears to be correcting that image.
However, I am not able to get much from the internet about the company Deutsche Gesellschafr Technische Zusammenarbeit GmbH .
To the best of my efforts the German company doesnt seem like an expert in algae technology.
Beckons claims that it has a PBR technology which is 125 times more efficient. One wonders " 125 times than what "
Beckons claims that it has tied up with several companies in South East Asia for technology transfer.
To me the entire PR exercise sounds like a stock market oriented news dissemination.
You can read the actual news here.
BSE-listed Beckons Industries, engaged in production of biodiesel, has entered into an agreement with Germany-based Deutsche Gesellschafr Technische Zusammenarbeit GmbH to set up a facility to produce algae and a Centre of Excellence in India.
The plant will have a production capacity of 2,400 tonnes a year of algae (the feedstock for biodiesel) dry mass that will sequester about 4,000 tonnes of CO2.
?The joint efforts will be towards scale-up, monitoring, measurements and rectification of minor deficiencies and will also offer a complete commercial process in the conversion of high lipid content algae to algae oil and algae biomass,? the company said in a press release.
Beckons is into development of PBR Algae Technology for large-scale commercial production of algae as feedstock for biodiesel.
The company plans to invest Rs 620 crore over five years.
It is in talks with power producers such as Adani and Tata for the sale of the PBR technology, which is similar to Fermenter which uses light energy as a source instead of carbohydrates as a medium.
Beckons recently signed agreements with Hong Kong-based Jilani International for transfer of its Algae technology to South Asian countries such as China, Taiwan, Hong Kong and Singapore.
