    For most of the 20th century, Lykes Bros. was one of the leading business players in Florida, with banks, utilities, a steel company, an orange juice factory and the world's largest steamship line. Today, Lykes is primarily an agricultural firm, with a ranch spanning Glades and Highlands counties and operations in cattle, citrus, sugarcane and pine, as well as insurance.

    Under CEO Howell Ferguson, great-grandson of company founder Howell Tyson Lykes, the company has embraced sustainable agriculture and environmental-services initiatives, such as the carbon-consulting spinoff Eco2Assets Solutions.

    Lykes has entered into a long-term agreement with Verenium and BP to provide land and biomass for a commercial cellulosic ethanol facility in Highlands County, now under construction. "Biofuels are a significant economic and environmental opportunity," says Ferguson, "not just for Lykes and for agriculture in general but for Florida."

    The firm, along with fellow agricultural powerhouse A. Duda & Sons, also wants to develop an intermodal logistics center in rural Glades County.

    Lykes is also #5 on the list of Florida's Biggest Private Landowners
