Hostess Brands’ shuttered bakery in Biddeford could soon have a new owner, but it’s not clear whether it would reopen or rehire any laid off employees. Georgia-based Flowers Foods has signed an agreement to buy the plant as part of its effort to acquire some assets of the bankrupt company, which made Wonder Bread, Twinkies and other baked goods. A spokesman for Flowers wouldn’t say Monday whether it would reopen the plant or rehire any of its 370 workers, who were laid off late last year when Hostess Brands Inc. ceased operating. Former employees, however, tell The Portland Press Herald (http://bit.ly/VXWwwH ) that they consider the sale a good sign. A Hostess spokesman said the auction will likely happen in late February and a sale could be completed by mid-March.
