Commercial at what cost?
I would think the closest to natural growth and the easiest to reproduce in an enclosed system to maintain purity should lead to commercial viability. If quantity is the primary limitation, GE by doubling size can make it commercially viable. We have no problem processing especially working with a larger size unit.

YES

hi everybody i am new to this

No, because chemical Engineering also can do it.

No, I think its more about the system growing it. Efficiency just needs to be increased.

It is not wise, to apply GE in algae.Even exotic algae causes harmful effect upon corals.For example Kappaphycus alvarezii causes death of coral on Gulf of Mannar,Tailnadu,India.Then, we would think the quantum of GE impacts upon algae.

There are many ways to increase algae growth rates, so GE is not necessary.

We have increased algae growth rates using Nano Iron on a Nano silica base.

No, we can not limit the solutions to just GE but it seems that GE can be considered to be the best solution so far.

Summarize all thoughts and publish a conclusion or report, which helps all...

pls tell me the effect of light intensity on the growth of microalgae.

Nope. Genetic Engineering at its best will always suffer from mutations and long term deterioration at its current maturity level. Genetic Engineering should remain a active research are, but field applications, in my opinion, are doomed to failure at the current maturity due to high mutation rates.

No, genetic engineering is not the only way, but it probably is the fastest way to reach our goals (whatever they might be) with algae. Maybe we should give it a try.....mother nature has been doing it for, what, billions of years. She has developed an algae for just about every nitch on the planet.
Is it wrong that we help mother nature in finding or making an algae for our specific nitch?

GE of what? Chlamydomonas reinhardtii? (for example) hummmm... This alga is the laboratory rat (or the E. coli, Caenorhabditis elegans, Drosophila melanogaster, Arabidopsis thaliana, etc.) for algae research. GE of Chlamydomonas reinhardtii for biofuel is the same that GE of laboratory rats (a known model organism for research on mammals) for protein production... Very comfortable (there is a lot of knowledge on these model organisms, as genomics, physiology, development, etc...). However, it is clear that energy conversion into proteins in a particulate system as rats (high surface/volume ratio, high metabolic rates, high losses of energy as heat…), has to be much less efficient than in cattle... This is not my opinion, but the human experience.
Well, my opinion is that if there is some probability of success finding an algae for bioenergy, we have to search for “the cattle algae” for oil and biofuel production. An unknown (or known but not considered or studied or not even discovered) photosynthetic “algal cow”…. Once we find it, we would be able to assay GM to improve their performance (as hundred years of human selection and genetics have resulted in a Hereford champion).

Best,

From my point of view, NO, there are are other ways to get commercial oil production from algae like wide range screening and adaptation of growth conditions ...etc. but we can say that the most important way is genetic engineering.

I would personally say - no - just look at what happen with other GE crops!!!

No. The use of genetic engineering reqires the installation of a whole new set of rules. It closes the playing field to a select few. GE foods are just now showing the problems. Plant hybridization & chemical assistance with compounds & xray should produce all the flexibility needed

We need GM. with abundant caution

Though I feel genetic engineering is not the way to go. The biotech company LS9 Inc. is using single-celled bacteria to create an oil equivalent. What people are trying to do with algae has already been tried with E coli. With E coli, the oil production can be much faster. I don't really know will Genetic engineering make any better algae that E coli.

NO' algae is jus the beginning...not jus for fuels..for so much more. look at what we did with corn.

No it is not. Don't mess with mother nature. Make good use of it. Explore the possibilities of sustainable production of algae. Rising oil prices will make alternative energy sources economical attractive in the future.

No, i don't think so...

NO! it is a component of the solution and a powerful tool but it is not the silver bullet. We are still in the dark ages when it comes to understanding exactly how algae works and applying it in a successful market model. Attitude is the single most important factor in making Algae fuel commercial.
