摘要： Mutant thermophilic organisms that consume a variety of biomass derived substrates are disclosed herein. Strains of Thermoanaerobacterium saccharolyticum with acetate kinase and phosphotransacetylase expression eliminated are disclosed herein. Further, strain ALK1 has been engineered by site directed homologous recombination to knockout both acetic acid and lactic acid production. Continuous culture involving a substrate concentration challenge lead to evolution of ALK1, and formation of a more robust strain designated ALK2. The organisms may be utilized for example in thermophilic SSF and SSCF reactions performed at temperatures that are optimal for cellulase activity to produce near theoretical ethanol yields without expressing pyruvate decarboxylase.
摘要翻译：本文公开了消耗多种生物质衍生底物的突变嗜热生物。本文公开了消除了乙酸激酶和磷酸转乙酰酶表达的酿酒酵母属杆菌菌株。此外，菌株ALK1已经通过位点定向同源重组进行工程化，以敲除乙酸和乳酸生产。涉及底物浓度挑战的连续培养导致ALK1的进化，并形成称为ALK2的更强壮的菌株。生物可以用于例如在对于纤维素酶活性最佳以在不表达丙酮酸脱羧酶的情况下产生接近理论乙醇产生的温度下进行的嗜热SSF和SSCF反应。

摘要： The present invention is directed to a process for biologically converting carbohydrates from lignocellulosic biomass comprising the steps of: suspending lignocellulosic biomass in a flow-through reactor, passing a reaction solution into the reactor, wherein the solution is absorbed into the biomass substrate and at least a portion of the solution migrates through said biomass substrate to a liquid reservoir, recirculating the reaction solution in the liquid reservoir at least once to be absorbed into and migrate through the biomass substrate again. The biological converting of the may involve hydrolyzing cellulose, hemicellulose, or a combination thereof to form oligosaccharides, monomelic sugars, or a combination thereof; fermenting oligosaccharides, monomelic sugars, or a combination thereof to produce ethanol, or a combination thereof.
