    摘要： Using screening of transposon random insertion mutants, genes involved in accumulation of (p)ppGpp were found to be involved in bacterial cell response to butanol. Reduced production of proteins with enzymatic activity for (p)ppGpp biosynthesis confers increased butanol tolerance. Bacterial strains with reduced (p)ppGpp accumulation and having a butanol or 2-butanone biosynthetic pathway are useful for production of butanol or 2-butanone.

    摘要： The present invention provides a process using zeolites for recovering isoflavones and removing undesired oligosaccharides from aqueous mixtures, such as soy whey and other plant processing waste products. The aqueous mixture is treated with a large pore hydrophobic zeolite, such as zeolite Beta, to remove isoflavones, followed by treatment with an ultrastabilized, hydrophobic zeolite Y, such as CBV-901 or HiSiv™ 4000, to remove the undesired oligosaccharides raffinose and stachyose. The recovered isoflavones and digestible sugars, glucose, sucrose, and fructose, are useful in food products.
