Weiss & Lurie, a national class action and shareholder rights law firm with offices in New York City and Los Angeles, is investigating possible breaches of fiduciary duty and other violations of law by members of the Board of Directors of Martek Biosciences Corporation (“Martek” or the “Company”) (NASDAQ: MATK) arising from the proposed acquisition of Martek by Royal DSM N.V. (“DSM”) (NYSE Euronext: DSM KON) for $31.50 per share. The transaction is valued at approximately $1.09 billion and is expected to close in the first half of 2011.
