We look anew at\u00a0Joule\u2019s quest, and its progress.<\/p>\n

\n

From\u00a0Massachusetts, word arrived from <\/b>Joule this week that the EPA has favorably reviewed the company\u2019s Microbial Commercial Activity Notice for Joule\u2019s first commercial ethanol-producing catalyst. This clears the catalyst for commercial use at the company\u2019s demonstration plant in New Mexico, the company says.<\/p>\n

There\u2019s been quite a bit of congratulatory chirping on the internet \u2014 and Joule was moved to put out a press release.<\/p>\n

\u201cThe favorable review of our first MCAN is an important step,\u201d said Paul Snaith, President and CEO of Joule. \u201cThis work will help us not only meet or better EPA regulations beyond our plant in Hobbs, but also outside the US as we industrialize our solar, CO2<\/sub>-to-fuels platform.\u201d<\/p>\n

Given that Joule, by and large, gives J.D. Salinger a decent run for its money in terms of avoiding the limelight, even a relatively benign statement from Paul Snaith inspires us in Digestville to look into it.<\/p>\n

In doing so, let\u2019s look at two questions.<\/p>\n

First, what exactly is a Microbial Commercial Activity Notice and should we all share Joule\u2019s enthusiasm over it? Second, what\u2019s up with the company perhaps most closely associated with the production of fuels directly from CO2, sunlight and water? They of the world of \u201cNo biomass, no petroleum, no kidding.\u201d<\/p>\n

More about Joule and its MCAN<\/h4>\n

First, what about that Microbial Commercial Activity Notice, which is known as an MCAN amongst the acronym-adoring sections of the Digesterati?<\/p>\n

On the one hand, this marks the first time that EPA has allowed the commercial use of a modified cyanobacterium. MCAN filings are required by the EPA prior to commercial use of certain modified microbes, including for biofuel or bio-based chemical production. In its review of Joule\u2019s MCAN, EPA had no health or safety objections to use of the modified strain at the Hobbs facility. Joule and EPA have entered into a voluntary consent order which allows Joule to use this catalyst strain commercially at the Hobbs facility, while also providing EPA with further data resulting from such use.<\/p>\n

On the other hand, MCANs are as rare as blood diamonds. Only 66 applications since 1998 have been filed \u2014 though the pace has quickened recently, with 25 filed since 2012.\u00a0 Joule itself filed in 2012 for commercial use of a modified Synechococcus, and received just about the only knock-back, picking up a consent order serving \u201cto limit the production, processing, distribution in commerce, use, and disposal of new chemical substances that raise health or environmental concerns, pending receipt of required information.\u201d<\/p>\n

More about Joule\u2019s latest declaration of activity<\/h4>\n

On the whole, Joule\u2019s demystified quite a bit in recent months. In this article, there\u2019s lots of actual photos available at jouleunlimited.com and more visualizations of their systems.<\/p>\n

But mysteries continue \u2014 as probably they should, given the company\u2019s unique and difficult quest.<\/p>\n

The MCANs itself don\u2019t reveal much about Joule \u2014 the 2012 notice did confirm that they have been working with the above-mentioned Synecocchus<\/em> \u2014 which is a gram-negative cyanobacteria. Probably a strain of Synecocchus elongatus<\/em>.<\/p>\n

The Joule Quest<\/h4>\n

But what exactly does that mean?<\/p>\n

Bottom line, Joule is trying to make a robust, economically viable strain of an alkanogen, alkeneogen or ethanologen. If you\u2019re wondering exactly what makes that a) interesting and b) hard to do, I\u2019ll try to explain.<\/p>\n

Any insertyourtargetproduct-ogen<\/em> is a rare and precious bird in the biofuels and chemicals trade. Reasonably\u00a0well\u00a0known from nature are methanogens and acetogens. These are organisms that secrete acetic acid or methane as part of their metabolic cycle. All humans, to make the comparison, are sweatogens. You labor, and your body secretes a sweat. Among mammals, almost all mothers secrete mother\u2019s milk.<\/p>\n

In this way, an ethanologen, alkeneogen or alkanogen is an organism that sweats ethanol, alkenes or alkanes. All you basically have to do is collect it, like milking a cow.<\/p>\n

Contrast that with most biomass-based enterprises, where you grow an organism, then harvest it, crush it, extract the useful material and discard the waste. Sort of like the slaughterhouse.<\/p>\n

Making Joule even more interesting \u2014 its organisms are trained to sweat diesel-range alkanes, or chemically high-value alkenes like ethylene or propylene. Or alcohols like ethanol. Now, if you think back to wild fraternity parties where, in the aftermath, you feel like you have to sweat out the excess alcohol in a steam bath \u2014 well, that\u2019s not entirely off the mark. Only this is done at a microscopic level. Synecocchus are so small that you can find thousands of them swimming around in a glassful of water you might pull out of a river.<\/p>\n

And, perhaps most remarkably of all, Joule\u2019s microorganism\u2019s don\u2019t require sugar as an input, or any kind of finished biomass-like material. Like the highly-trained microbes at, say INEOS Bio or LanzaTech, they can get their carbon in gas form. In the case of Joule\u2019s organisms, they use CO2, sunlight and water as the most plentiful inputs.<\/p>\n

Plenty of organisms use those same inputs \u2014 all photosynthetic microalgae, for example. But you can\u2019t milk them like a cow. You have to crush them.<\/p>\n

Among all companies out there \u2014 generally speaking just Algenol and Joule have gone down this path of creating an ethanologen that you can milk. Joule has taken it one step further by aiming for an alkanogen. That is, a milkable microbe that makes diesel or jet fuel directly from C)2, sunlight and water.<\/p>\n

Which is why just about everyone\u2019s ears perk up when you utter the magic word: \u201cJoule\u201d. But a number of observers as generally dismissed the exercise as basically a fool\u2019s errand, somewhere between hype and downright dangerous BS of the kind that gives synthetic biology a bad name. Here in Digestville, we\u2019re not in that camp, though the news flow has been sketchy enough to encourage both the skeptics and the believers.<\/p>\n

What\u2019s going on inside the Magic Temple<\/h4>\n

What\u2019s going on behind the scenes in the world of Joule? Generally, the work falls in four areas.<\/p>\n

1. Getting the organism to over-produce the alkane, alkene or alcohol of interest.<\/p>\n

2. Getting a cost efficient photobioreactor design.<\/p>\n

3. Controlling heat. Systems heat up in the day, when the sun is out. Cooling costs money.<\/p>\n

4. Looking at ways to extend an organism\u2019s productivity from \u201cdaylight hours\u201d to \u201cround the clock\u201d.<\/p>\n

Of all of the four, perhaps the fourth is the most fascinating and elusive of all., Because they would have to endow a photosynthetic organism with heterotrophic properties \u2014 train it to extract energy from sunlight by day, then extract if from sugar by night. That\u2019s known as mixotrophic properties, and such organisms do exists. But they don\u2019t, er, happen to naturally secrete diesel and jet fuel.<\/p>\n

But there\u2019s been work done, interestingly including Joule, and synecocchus elongatus.\u00a0 Last yearf we reported on efforts out of UC Davis to convert an obligate photoautotroph to a heterotroph is desirable for more efficient, economical and controllable production systems. More on that here.<\/p>\n

Joule\u2019s \u201ccarbon based products of interest\u201d<\/h4>\n

Let\u2019s just say that Joule has a broad array of molecules of interest. In recent submissions they have cited:<\/p>\n

ethanol, propanol, isopropanol, butanol, fatty alcohols, fatty acid esters, ethyl esters, wax esters; hydrocarbons and alkanes such as propane, octane, diesel, Jet Propellant 8 (JP8); polymers such as terephthalate, 1,3-propanediol, 1,4-butanediol, polyols, Polyhydroxyalkanoates (PHA), poly-beta-hydroxybutyrate (PHB), acrylate, adipic acid, \u03b5-caprolactone, isoprene, caprolactam, rubber; commodity chemicals such as lactate, docosahexaenoic acid (DHA), 3-hydroxypropionate, \u03b3-valerolactone, lysine, serine, aspartate, aspartic acid, sorbitol, ascorbate, ascorbic acid, isopentenol, lanosterol, omega-3 DHA, lycopene, itaconate, 1,3-butadiene, ethylene, propylene, succinate, citrate, citric acid, glutamate, malate, 3-hydroxypropionic acid (HPA), lactic acid, THF, gamma butyrolactone, pyrrolidones, hydroxybutyrate, glutamic acid, levulinic acid, acrylic acid, malonic acid; specialty chemicals such as carotenoids, isoprenoids, itaconic acid; pharmaceuticals and pharmaceutical intermediates such as 7-aminodeacetoxycephalosporanic acid (7-ADCA)\/cephalosporin, erythromycin, polyketides, statins, paclitaxel, docetaxel, terpenes, peptides, steroids, omega fatty acids and other such suitable products of interest. Such products are useful in the context of biofuels, industrial and specialty chemicals, as intermediates used to make additional products, such as nutritional supplements, nutraceuticals, polymers, paraffin replacements, personal care products and pharmaceuticals.<\/em><\/p>\n

They appear to have overlooked kryptonite and vibranium, but not much else.<\/p>\n

Joule\u2019s patent app stream<\/h4>\n

To monitor their progress on other fronts, let look at their recent patent apps.<\/p>\n

The bottom line<\/h4>\n

They\u2019re still working on the bioreactor design, as far as we can tell \u2014 shaking costs out of the system. Meanwhile, training the microbe to make interesting chemicals, the alkenes. And continuing to improve the alkane flow. All the while investigating the development of a 24\/7 organism, or set of them.<\/p>\n

Looks like we are some distance from a commercially scalable system. But my goodness, they\u2019re making a lot of progress. Just one successful company in this space \u2014 well, that will rock the world.<\/p>\n
