The Project
Our Human Practices
Exploring Consumer Reactions
The biological portion of our project altered the cellulose produced by acetobacter xylinum for use as a fabrication material in consumer products. Accordingly, the human practices portion of our project focused on the consumer market for genetically modified (GM) products and sought to identify the primary demographic and psychographic predictors of approval for those products. We used both quantitative and qualitative measures to research this question.
The quantitative measure was in the form of a ten item survey administered to a national sample via the world wide web. The survey asked respondents whether they were aware that GM food and cotton were already sold in stores, whether they approved of GM food, clothes, fuels, and medicine, how safe they perceived GM products to be, and basic demographic information including their age, gender, and highest level of education completed. A 37 percent response rate yielded 168 usable responses, and results are reported with 95 percent confidence and a confidence interval of 7.5 percent. We found that product type, gender, and awareness of existing GM products were all predictors of approval for GM products. We also found that women were significantly less likely to approve of GM products (p
As a qualitative measure of opinion concerning GM products, we created an artificial store selling GM products at a widely attended street festival in Brooklyn, NY and interviewed visitors concerning their perceptions of actual and hypothetical GM products on display at the store. We interviewed women in particular and found that the perception of GM products as unsafe or untrustworthy is a likely cause of disapproval for GM products.
The Survey
Our human practices portion consists of a study concerning relationships among awareness, education, and approval of different genetically modified products. e.g. Do people care whether cotton is genetically engineered as much as food? The survey results were collected online as well as our shoppe at Atlantic Antic from volunteers off the street.
Methodology
- 10 item web survey regarding genetically modified (GM) products:
- Awareness that GM food and cotton are sold (2 items).
- Approval for GM food, clothes, fuel and medicine (4 items).
- Perceived safety of GM products (1 item).
- Age, gender and education (3 items).
- Respondents were recruited by a survey research firm using email and online advertising, and through social networks.
- Most respondents received $0.50 to a charity or the chance to win $100 in an online sweepstakes.
- Survey administered the week of 9/21/12.
Sample Overview
- National sample, including more than 50 U.S. metro areas.
- 37 percent response rate, 168 usable responses.
Results
The results of our survey showed some interesting insights into the way different types of people view GM products.
Approval Varies by Type
Approval Varies by Gender
Women seem to approve of GM products much less than men.
Effect of Awareness on Approval
GM Awareness has a limited effect on approval.
Summary
- Product type, gender, awareness all affect approval for GM products.
- Increasing GM awareness primarily influences undecideds.
- Age and education showed no significant effect.
- Results are 95 percent confidence +/- 7.5 percent.
- Further research needed to examine the mechanism affecting approval. We believe perceived risk versus reward and emotions of disgust and fear are likely drivers.
The Shop
To showcase the wonder and power of genetically modified products to the public, we setup a one-day-only popup shop in Brooklyn, NY on the day of the biggest street fair in New York City -- The Atlantic Antic! With tons of street traffic and several film crews documenting the day and interviewing visitors, the store was a huge success. Check out some of the "products" we were selling that day.
GMO based consumer products: Present and Future
Living Watch
This biologically based oscillator is attuned not only to lunar and solar cycles, but to biological circadian rhythms as well. Housed in an organic scaffold and bezel setting, the time is digitally indicated by truly organic light emitting diodes; cells that have been genetically modified to bio-luminesce in response to oscillating genetic circuits. With a housing and strap made from laboratory grown keratinocytes and chondrocytes (a.k.a. Victimless Leather), it ensures complete biodegradability when time runs out.

MicroAlgae BioDiesel
Everyone is going green these days, including the U.S. Navy! The grown photosynthetic algae harvests CO2 directly from the atmosphere and uses sunlight to biosynthesize energy packed hydrocarbons. Since the CO2 that is subsequently released from the burning of this fuel has been taken up from the atmosphere, the result is a net carbon-neutral load on the environment. New strains are being genetically engineered to produce higher yields of hydrocarbons which can be used to power everything from F-18 Hornets to the family sedan.
Availability: Near Future
Enzyme based Cleaners
The addition of genetically modified enzymes that degrade proteins (proteases), carbohydrates (amylases) and greases (lipases) to cleaning compounds such as detergents, surface cleaners, contact lens solutions, etc. ensures the speedy removal of accumulated dirt. In addition, enzymes function at lower temperatures, thereby reducing the need for hot water during cleaning. A sample, by no means complete, of some products that contain enzymes for cleaning purposes is on display here.

The Harvard iGARDEN
Designed as an “open source tool-kit for plant engineering”, the iGARDEN kit was created by Harvard University students during the 2010 International Genetic Engineering competition.
From the Harvard Team IGEM 2010 website:
“The Harvard iGarden is a venture into plant engineering. Our aim is to create a toolkit for the cultivation of a personalized garden containing features introduced through synthetic biology. In addition to a "genetic fence" designed to prevent the spread of introduced genetic material, we have developed three independent features to be included in this toolkit - inclusion of novel flavors, knockdown of plant allergens, and modification of petal color. We envision the iGarden as a medium through which the non-scientist can see the power and potential of synthetic biology and apply it to everyday life.”

Gen2Seat (Generation 2, Seat)
Furniture that is grown using biopolymers derived from genetically modified Acetobacter strains, isolated from Kombucha, that secrete chitin, a durable material also found in insect exoskeletons. What will they think of next! Draped over an interior cushioning derived from fungal mycelia, this chair is light, sturdy and eventually compostable. This consumer item is designed to be produced using a minimum of energy expenditure and is currently being developed by the NYU-Gallatin IGEM team, along with members of Terreform One and Genspace.
Availability: Very Near Future
BioProgrammable Paint
Not sure what color to paint your walls? Decide later with programmable paint! Contains micro-encapsulated strains of genetically engineered B. subtilis bacteria. Each bacterium contains a series of genes cloned from various plant biosynthetic pathways that synthesize pigment molecules, such as red lycopene found in tomatoes and orange beta-carotene found in carrots. When freshly applied, the oxygen activated microbes get to work, producing a slowly changing spectrum of synchronized color on applied surfaces for up to a week, with previous pigments being degraded. When your favorite color comes into view, simply wave the enclosed UV emitting wand in the direction of the surface to disable the bacteria and lock in the color. Improved varieties of programmable paint are being worked on that will also absorb allergens and toxins such as carbon monoxide and mold spores.

Genetically Modified Foods
Currently at the center of various controversies, genetically modified crops come in a range of varieties. Crops that have been developed today include varieties of maize, soy and alfalfa, that express genes from the naturally occurring soil bacterium B. thuringiensis. The expressed protein is fatal to insect larvae when they ingest the crops. Most current crops are engineered to be either pest or herbicide resistant. Future varieties of food crop plants are being engineered to have enhanced production of nutrients. Golden rice varieties have been engineered that produce beta-carotene (Viatmin A). Currently 80% of papayas grown in Hawaii are derived from a variety that has been genetically engineered to contain a gene making it resistant to papaya ringspot virus, a natural pest of the papaya plant.

Detergent enzymes
Taken From Novozymes.com:
Enzymes have been used in detergents since the 1960s. The use of enzymes in laundry and automatic dish washing detergents provides consumers with well proven benefits - both in the washing process itself and in terms of the wider environment.
Enzymes can reduce the environmental load of detergent products since they:
• Save energy and CO2 emissions by enabling lower wash temperatures while maintaining washing performance
• Partly replace other chemicals in detergents, such as surfactants
• Enable compactation, reducing packaging and transportation costs
• Are biodegradable, leaving no harmful residues
• Have no negative environmental impact on sewage treatment processes
• Do not present a risk to aquatic life
Laundry washing is one of the activities that consume the most energy in an ordinary household. By washing at 30 rather than 60 or 40 degrees, the CO2 savings potential in Europe and the US is around 32 million tons – equivalent to the emission of 8 million cars.
Position on detergent enzymes
The use of enzymes in detergents provides consumers with well proven benefits. Detergent enzymes present no risk to consumers, nor to employees in detergent production, provided a few simple precautionary measurements are followed in order to avoid the generation of airborne enzyme dust or aerosol.
No health risk
At Novozymes only well-known and safe microorganisms is used for enzyme production. Novozymes applies genetic engineering to benefit optimally from the company’s production plants and raw materials - to the clear benefit of the environment.
During the production process the enzyme products are recovered from the genetically modified organisms (GMO) and purified. Therefore there are no GMOs present neither in Novozymes' enzyme products. Moreover, Novozymes' production activities are approved and closely regulated and monitored by the Danish environmental authorities.
Encapsulated or liquid enzymes can be handled conveniently and safely.
Modern biotechnology and detergent enzymes
Man's use of enzyme reactions dates back to antiquity. The making of cheese, vinegar and wine, the leavening of bread, and the brewing of beer are all enzymatic processes which have their origins in prehistory.
In the past few decades the industry has increased its use of enzymes, and enzymes are now widely used in many different industries. As they can often replace harsh chemicals and help save on water, energy and raw materials, they have a positive impact on the environment.
Enzymes are widely used in the detergent industry where they provide clear cleaning performance benefits in laundry and dish washing detergent products. Enzyme properties may also be improved by the use of protein engineering technique whereby specific amino acid substitutions in the enzyme are coded for in the enzyme gene.
Examples are the surfactant replacing enzyme Lipoclean, the improved cold washing efficiency of Polarzyme, and the bleach-resistant starch degrading enzyme Duramyl.
