UCSC iGem 2016: Sugar Slugs

UCSC’s 2016 iGEM team has finally had their crowd-funding site go live at  They have an interesting project this year:

Engineering a Better Future

The world of crop production is laden with agricultural co-products that are unfit for human consumption. The vision of the UCSC iGEM team is to develop a novel process for converting these co-products into the high-value sweetener, Erythritol. It’s simple, sweet, and best of all, zero-calorie.

Ever wanted a bioreactor you can control at the click of a button? Our team is also designing and building our very own autonomous bioreactor, the Taris V1. Whether its temperature, pH, nutrient uptake, or beyond, our bioreactor will also monitor and feed its internal conditions into an online interface where users can seamlessly track their data and change conditions as they see fit. Talk about convenience.

With its low cost and ease-of-use, we hope our Taris V1 bioreactor can serve as a platform for other teams across the globe to create innovative solutions to real-world problems.

I don’t know much about what they are doing for the metabolic engineering to make the erythritol, but the bioreactor project is a rather fun “maker” project.

They have posted their budget on-line, and by far the largest cost is getting to the iGEM “Jamboree” in Boston in October. All the lab equipment is provided by UCSC (except the bioreactor they are designing and building), and all the student labor is free (in fact, they are paying summer tuition in order to take the iGEM course). So they have about $1000 for hardware, <$200 for reagents, and $31,300 for travel to the conference.  I think that they’ve over-estimated the price of flying to Boston, though, as Southwest flights are currently about $320 round-trip, and ground transportation at each end would probably add only about $200 to that, so 21 people  (20 undergrads and 1 instructor) should be able to do the travel part for under $11,000.  They’ve probably underestimated the lodging costs though, unless they are planning to pack like sardines into an AirBNB rental.

I’ve been thinking of going to the iGEM conference myself this year (on my own money, not crowd-funded), as I’ll be on sabbatical in October, and not teaching. I’ll have to make up my mind soon, though, as the cheap flight prices will probably go away.

I’ll be giving the iGEM team some money for their crowd-funding campaign, as it would be valuable for all of them to be able to attend the conference after the work they’ve put in—I know many of the students on the team this year, and they are the hard-working students that teachers love to have in their classes.

I urge others to make at least a token donation, to let them know that the hard work they are doing is recognized by the community.  Donations can be made through the UCSC crowd-funding site.

Disclaimer: I’m officially the “2nd PI” for the iGEM team this year, because the iGEM organization insisted on there being two faculty involved. I’ve done some advising on the bioreactor project also, though only through a few conversations with the lead designer on that team (who was also my group tutor for my applied electronics course in the spring).
