A process for fermenting syngas and a fermentation medium provides high ethanol productivity while removing medium components that were previously thought to be essential. The process is effective for providing a specific STY of at least about 1 g ethanol/(L•day•gram cells). In this aspect, the fermentation medium has a weight ratio of NH4+ to B of about 625:1 or more, or a weight ratio of NH4+ to Mn of about 4050:1 or more, or a weight ratio of NH4+ to Mo of about 2500:1 or more, or a ratio of NH4+ to Cu of about 4050:1 or more; or the fermentation medium has a weight ratio of P to B of about 30:1 or more, or a weight ratio of P to Mn of about 190:1 or more, or a weight ratio of P to Mo of about 120:1 or more, or a weight ratio of Mn to Cu of about 190:1 or more; or the fermentation medium has a weight ratio of K to B of about 35:1 or more, or a weight ratio of K to Mn of about 245:1 or more, or a weight ratio of K to Mo of about 150:1 or more, or a weight ratio of K to Cu of about 245:1 or more.
