INITIAL PUBLIC OFFERINGS:

PetroAlgae and Gevo, two alternative fuel and chemical companies, hope to fire up the tepid IPO waters. PetroAlgae, which produces biocrude from duckweed, has not generated any revenue yet, and has just filed to go public. The Florida-based renewable energy company, which has traded over-the-counter under an inactive shell corporation, hopes to raise $200 million. The underwriters of the offering are Goldman Sachs; UBS Investment Bank, and Citi.
