  • Publication number: 20130273555
    Abstract: One aspect of the invention relates to a genetically modified thermophilic or mesophilic microorganism, wherein a first native gene is partially, substantially, or completely deleted, silenced, inactivated, or down-regulated, which first native gene encodes a first native enzyme involved in the metabolic production of an organic acid or a salt thereof, thereby increasing the native ability of said thermophilic or mesophilic microorganism to produce lactate or acetate as a fermentation product. In certain embodiments, the aforementioned microorganism further comprises a first non-native gene, which first non-native gene encodes a first non-native enzyme involved in the metabolic production of lactate or acetate. Another aspect of the invention relates to a process for converting lignocellulosic biomass to lactate or acetate, comprising contacting lignocellulosic biomass with a genetically modified thermophilic or mesophilic microorganism.

  • Publication number: 20120129229
    Abstract: Host cells, comprising Kluveryomyces expressing heterologous cellulases produce ethanol from cellulose In addition, multiple host cells expressing different heterlogous cellulases can be co-cultured together and used to produce ethanol from cellulose The recombinant yeast strains and co-cultures of the yeast strains can be used to produce ethanol on their own, or can also be used in combination with externally added cellulases to increase the efficiency of sacchanfication and fermentation processes

  • Publication number: 20090207094
    Abstract: An antenna is connected to a connector disclosed in the present disclosure, and the connector has a clamping slot adapted to fix a radio remote unit (RRU). A clamping slot tight side may be set on the connector to fasten the RRU, and an RRU fastening hole may be set on the connector to fasten the RRU. An RF apparatus integrated with a connector is also disclosed. According to the present disclosure, the antenna and the RRU are fixed to the connector. This makes it unnecessary to provide additional spaces and supports for installing the RRU. Hence, the RRU can be installed in a proper position and the installation costs can be reduced. In addition, the distance between the antenna and the RRU is shortened. Thus, the cable (when necessary) between the antenna and the RRU is shorter than that in the prior art. This greatly reduces signal transmission losses.
