Marrone Bio Innovations Presents Positive Data on Treatment for Invasive Zebra and Quagga Mussels at HydroVision International Conference

Studies show Zequanox is highly selective and of low toxicity to non-target organisms.

Marrone Bio Innovations, Inc. (MBI), a leading global provider of natural pest management products for the agricultural and water treatment markets, announced today that it will release new data from facility treatments and pilot studies of Zequanox® during a poster presentation at HydroVision International, the world’s largest gathering of hydropower professionals, in Louisville, Kentucky from July 17-20. Zequanox, which was approved by the U.S. Environmental Protection Agency in 2011, is the industry's first biological alternative for controlling invasive zebra and quagga mussels.

The poster, titled “An Environmentally Compatible Weapon for the War against Invasive Mussels,” will be presented on Thursday, July 19th from 8:30 a.m. to 10 a.m. in the Poster Gallery. MBI Director of Water Technologies Sarahann Rackl will present the poster, which was co-authored with Carolyn Link, Senior Scientist, and Bridget Gruber, aquatic products development specialist of Marrone Bio Innovations and Leonard Willet, Lower Colorado Dams quagga mussel coordinator and WTP manager, of the U.S. Bureau of Reclamation in Boulder City, Nevada.

The poster summarizes the results from cooling water sub-system treatments and pilot demonstration studies conducted by MBI in 2011 at the U.S. Bureau of Reclamation’s Davis Dam and other locations. Results of these treatments demonstrate that Zequanox is an effective solution for controlling invasive mussels in various water conditions. Specially, the studies concluded:

> Zequanox treatments can achieve control comparable to other chemical products of both zebra and quagga mussels
> One-time Zequanox treatments can provide sufficient control of adult mussels
> Mussel management strategies can employ repeated treatments at lower concentrations to achieve goals by taking advantage of cumulative effects
> Successive treatments on recently settled mussels can achieve a high level of control
> Zequanox can provide effective mussel control without harm to the surrounding aquatic ecosystem

“The success we have seen with Zequanox is an important validation of the product’s effectiveness and the fact that a biological control solution can be used to control mussels within cooling water systems,” Rackl said. “As the only environmentally compatible product for treating zebra and quagga mussels, Zequanox is a powerful weapon for hydropower facilities seeking to protect their systems without putting their employees at risk or threatening the environment.”

Zebra and quagga mussels were first discovered to have invaded the Great Lakes in the late 1980s and have since invaded waterways across the United States. These mussels rapidly reproduce and within weeks or months can cover and damage equipment as well as clog water intake pipes, preventing the flow of critical cooling water. For hydropower facilities, mussel fouling increases maintenance costs, can reduce power production, and can lead to an increased number of planned and unplanned outages. According to the United States Office of Technology Assessment, invasive mussels cause an estimated $1 billion in economic impact annually. Yet regulatory restraints and environmental concerns have forced many facility operators to limit their use of chemicals for treating service water systems.

MBI developed Zequanox, an environmentally compatible biopesticide derived from the naturally occurring microbe Pseudomonas fluorescens, to address this challenge. Zequanox is comprised entirely of dead cells.
