  • I have sent my lipid and biodiesel sample from algae for Carbon Chain Distribution test for GC analysis. But they couldn't not detect any readings. They are saying that my sample is soluble in water. Can anyone help me to overcome this problem?

      prepare ur sample once again..sent to some other labs......... while oil xttrctn care shld be takn..then phase separation chloroform layer only u have to collect.then go for transtrifictn method then add hexane......collect the hexane layer...was with water to seprte the glycrin...then collct the haxne lyer send for GC

  • Does anyone know any other "cleantech" sites that pick up news on the innovation front, news on science behind algae or other sources with information i can take a look on? Feels like cleantech is a bit dead for a 18 year old dude like myself =)

  • I really want to run some experiments growing algae heterotrophically or maybe mixotrophically. I have heard that cell densities as well as lipid content can get to very high levels. But I am having trouble finding good literature [technical or otherwise] to base experiments from. Could someone please help me out, or at least point me in the right direction

      Hi, Get hold of Mr. Mayakannan from CAS botany Madras University, presently working as Phycologist in Algaetech Inte rnational. He mapped different fresh water algae in whole of Tamil Nadu. He can help you with that. The other option would be to check barathidasan universities National facility for Marine Cyanobacteria. They might have some list of common microalgae in Tamil Nadu Coastal line. Pls Check - http://www.nfmc.res.in/list.html

    • Parkavi 4 years ago

      Hello, there are various types of extraction methods, the most commonly used extraction method for pharma and food grade DHA or EPA is SC CO2 (supercritical fluid extraction). This method is highly efficient in terms of quantity and quality. The pressure and temperature depends on the combination of fatty acids. Some algae contains only EPA or DHA in higher amount and some algae contains both DHA and EPA. Trials are required to find out optimum temperature/pressure for a particular algae species. A Similar work has been carried out by University of Perugia, Italy. Here is a link to the published paper - http://www.isasf.net/fileadmin/files/Docs/Versailles/Papers/N4.pdf. This temperature and pressure given can be used as a benchmark.
