Proterro Receives USPTO Patent for Cyanobacteria Used for Biochemicals Production

Published on 2013-02-21. Author : SpecialChem

EWING, New Jersey -- Proterro, Inc., the only company making sugar instead of extracting it from crops, has added to its executive team Edi Eliezer, as the company's engineering vice president, effective Feb.1, 2013. Eliezer joins Proterro with three decades in industrial bioengineering, with expertise in biochemicals and biofuels, and deep commercial operations experience in bioprocess development, fermentation systems, bioreactor design, facility engineering, scale-up and downstream/upstream process integration.

The United States Patent and Trademark Office issued a composition of matter patent Number 8,367,379 issued on February 5 that protects Proterro's unique engineered photosynthetic cyanobacteria and their genetic code. The issued patent is directed to the sequence and assembly of discrete genes of engineered cyanobacteria and the cyanobacteria themselves, which Proterro uses in a biosynthetic process to manufacture affordable sucrose for the economical and scalable production of biofuels and biobased chemicals.

The patent protects the genetic blueprint of these sucrose-producing microorganisms and is the cornerstone of Proterro's patent portfolio. The company has seven more U.S. patent applications and multiple foreign patent applications pending.

"These engineered cyanobacteria, which require a combination of only water, carbon dioxide, sunlight and nutrients to produce sucrose in a biosynthetic process at consistently high yields, are what make us different from our perceived competitors," said CEO Kasdin. "With our recent funding, expanded executive team and the patent issuance, Proterro is making great progress in developing the answer to the high cost of feedstock," she continued.

About Proterro

Proterro is the only company that makes sucrose instead of extracting it from crops. Proterro combines its core, patented "microorganism technology" with its patent-pending, high-density, modular, solid-phase photobioreactor for scalable production of the only non-crop-based, noncellulosic, clean sucrose that avoids the pricing volatility associated with corn and other feedstock markets. The company projects it can produce its sucrose at a cost of less than $.05/lb., which is far less than sugarcane, corn, other energy crops, or cellulosic sugar approaches. Proterro CEO Kasdin has been named one of the top 100 people in bioenergy (for two consecutive years), as well as one of the top 10 influential women in the biofuel business. The company has been recognized by Lux Research as a top innovative company that stands out for its "disruptive potential." Proterro's leadership team includes advisors with extensive experience from BP, Cargill, Gevo and Solazyme. The company is backed by Battelle Ventures, Braemar Energy Ventures, Cultivian Ventures and Middleland Capital.
