Farsighted vision based on bio-convergence is driving two Israeli companies towards the development of innovative materials: Seevix has developed a fiber inspired by spiderwebs \u2013 the ‘Holy Grail’ of the world of materials \u2013 while Enzymit designs and builds enzymes, biological nanomachines capable of creating any material.<\/h5>\n\n\n\n
<\/p>\n\n\n\n
“Every cell on earth contains thousands of different enzymes which are, actually, machines working inside the cells”, explains Dr. Gideon Lapidoth, co-founder and CEO of Enzymit<\/strong>. “Some of them break down food while others build new materials. Without these machines, life as we know it could not exist”.<\/p>\n\n\n\n
Enzymes are nature’s production machines: “You put something in on one side and something else comes out on the other side”, Dr. Lapidoth explains. “For example, in the process of photosynthesis, plants take CO2 (Carbon Dioxide) from the air and, using solar energy, convert it into sugar. In other words, the enzymes convert solar energy into chemical energy. At Enzymit, we do what the enzymes do, only artificially and more efficiently. Moreover, we can also produce materials that don’t even exist in nature”. \u00a0\u00a0<\/p>\n\n\n\n
In a study he conducted at the Weizman Institute, Dr. Lapidoth examined ways of designing proteins that can serve as biological nanomachines capable of building real materials, atom by atom, just like machines in the real world. “Nanotechnology enables us to play with atoms and molecules to produce new materials for various fields \u2013 for example, food, cosmetics, and pharmaceuticals. So, instead of using standard chemistry, we create enzymes that don’t exist in nature to act as machines that will produce these materials for us”, he explains.<\/p>\n\n\n\n

From Chemical to Biological Production<\/h2>\n\n\n\n
At the forefront of Dr. Lapidoth’s work is the aspiration to create materials in a process that is better, cheaper, and more efficient than what is possible using chemical production \u2013 the predominant form of production in the modern world. “Everyone realizes that biological production is greener and better for the environment than chemical production which causes pollution”, Dr. Lapidoth explains. “The problem lies with the cost: fermentation-based biological production is very expensive. For example, biological fuel is more expensive than fuel produced from oil. However, an enzymatic process allows us to produce fuel at a lower cost than is possible today and, no less important, it doesn’t pollute the environment”.<\/p>\n\n\n\n
Enzymit has built and continues to develop a technological platform and computing capabilities, developing algorithms that design new proteins. “Imagine, for example, plastic based on sugar or even CO2, instead of oil”, Dr. Lapidoth suggests. “This could mean a limitless supply of raw material that is also biodegradable.<\/p>\n\n\n\n
“We examine this from an engineering angle and then design an enzyme capable of generating a chemical reaction. For example, an enzyme that can convert CO2 into sugar, or turn simple sugar (monosaccharide) into a more complex and expensive material”, Dr. Lapidoth says.<\/p>\n\n\n\n
The initial materials developed by the company are already on the market. The first of these is a hyaluronic acid produced in an enzymatic process from a monosaccharide. Hyaluronic acid has many uses in the cosmetics and health industries and is traditionally produced primarily from chicken comb or bacteria.<\/p>\n\n\n\n
“The hyaluronic acid we produce is cleaner and of higher quality than the existing acid. The process is low-cost, quick, and is performed without cells, yeast, or bacteria”. The goal for the future is that the process will start with white sugar rather than with CO2.<\/p>\n\n\n\n
Enzymit is also working on an enzymatic process of converting cheap oils such as canola or palm oil into oils that possess qualities of olive oil or animal oil, but without involving live cells or animals in the process.<\/p>\n\n\n\n

The Magic of Enzymes<\/h2>\n\n\n\n
The method’s advantages are clear: it is just as efficient as chemical production, but without all the environmental damage and all the unhealthy conditions, and is performed efficiently, within several minutes or just a few hours. “It’s actually like magic”, says Dr. Lapidoth. “An enzyme is like a printer: you put in the ink and something else comes out the other end. The computation side of things is the planning of the printer and its production. At Enzymit, we took the old trial-and-error process and turned it into a planned engineering process.<\/p>\n\n\n\n
“Our vision is to build a bioreactor process whereby CO2 is fed into one side and starch, cellulose, or plastic is emitted on the other side. I know it will work \u2013 at present it is just a question of budget. I am sure that in several years it will be possible to do this cheaper than in any other, more cumbersome method.<\/p>\n\n\n\n
“Instead of growing huge fields of cotton to produce cellulose, I will have a bioreactor that will take CO2 and convert it into cellulose. Ultimately, it is all just a chemical process in which a very cheap raw material is converted into a product that has value. I am sure that we can build a machine that converts CO2 into food or fuel.<\/p>\n\n\n\n
