The present invention provides for novel metabolic pathways leading to propanol, alcohol or polyol formation in a consolidated bioprocessing system (CBP), where lignocellulosic biomass is efficiently converted to such products. More specifically, the invention provides for a recombinant microorganism, where the microorganism expresses one or more native and/or heterologous enzymes; where the one or more enzymes function in one or more engineered metabolic pathways to achieve: (1) conversion of a carbohydrate source to 1,2-propanediol, isopropropanol, ethanol and/or glycerol; (2) conversion of a carbohydrate source to n-propanol and isopropanol; (3) conversion of a carbohydrate source to isopropanol and methanol; or (4) conversion of a carbohydrate source to propanediol and acetone; wherein the one or more native and/or heterologous enzymes is activated, upregulated or downregulated.

Production of propanols, alcohols, and polyols in consolidated bioprocessing organisms

An apparatus and method for sterilizing, seeding, culturing, storing, shipping, and testing three-dimensional tissue constructs is disclosed. The apparatus includes a fluid reservoir, a pump, at least one treatment chamber, and a means for controlling media flow characteristics around a tissue construct disposed within the treatment chamber, and for controlling movement of the construct itself, so as to simulate a variety of physiologic conditions. One exemplary embodiment of the invention includes a means for applying an axial stress to the construct. Applying an axial stress to the construct during seeding and culturing results in a tissue-engineered construct with cells and their fibers oriented in a manner which is more likely to possess long term dimensional stability and the patency of native vessels with normal physiologic function.

An apparatus and method for sterilizing, seeding, culturing, storing, shipping, and testing cartilage constructs is disclosed. The apparatus generally includes a treatment chamber and a means for varying the fluid flow and pressure within the treatment chamber during seeding and culturing. The application of pressure to the cartilage construct improves both the uniformity of seeding throughout the construct and facilitates the flow of nutrients to and removal of waste products from cells embedded in the construct. In this manner, a tissue-engineered cartilage construct with cells and their fibers oriented in a manner which is more likely to possess long term dimensional stability and the patency of cartilage with normal physiologic function may be formed.

An apparatus for the large scale culturing and packaging of cell suspensions, three dimensional tissue, and other biological systems is disclosed. The apparatus includes a plurality of flexible or semi-flexible treatment chambers comprising one or more individual culture pockets, a plurality of rigid spacers, an inlet fluid manifold, an outlet fluid manifold, a fluid reservoir, and a means for transporting fluid within the system. During treatment, liquid media is transported from the fluid reservoir to the inlet manifold, which will in turn evenly distribute the media to each of the connected treatment chambers and internal culture pockets. An outlet fluid manifold is also provided to ensure that each treatment chamber is evenly filled and to ensure that any air bubbles formed during treatment are removed from the treatment chambers. The treatment chambers are flexible or semi-flexible so as to provide for easy end-user handling during rinsing and application of the cultured transplants. Due to the flexibility of the treatment chambers, rigid spacers are also provided which ensure even fluid distribution within the chambers during treatment.
