  • Publication number: 20240093514
    Abstract: A base for use with scaffolding. The base includes side support members and cross members. The side support members have scaffold receiving members provided at ends thereof. The cross members extend between the side support members and are rotatably mounted to the side support members. Wheels are mounted to the cross members. As the cross members are rotated from a first position to a second position, the wheels are moved from an initial position in which the wheels are spaced from a ground or floor surface to a second position in which the wheels are positioned in engagement with the ground or floor surface.

  • Publication number: 20240026393
    Abstract: Muconic acid is a molecule that can be converted into direct replacement chemicals for incumbent petrochemicals and performance-advantaged bioproducts. Disclosed herein are Pseudomonas putida KT2440 that are engineered to convert glucose and xylose, the primary carbohydrates in lignocellulosic hydrolysates, to muconic acid using a model-guided strategy to maximize the theoretical yield. Using adaptive laboratory evolution (ALE) and metabolic engineering in a strain engineered to express the D-xylose isomerase pathway, we demonstrated that mutations in the heterologous D-xylose:H+ symporter (XylE), increased expression of a major facilitator superfamily transporter (PP_2569), and overexpression of aroB encoding the native 3-dehydroquinate synthase, enable efficient muconic acid production from glucose and xylose simultaneously. Using the rationally engineered strain, we produced 33.7 g/L muconate at 0.18 g/L/h and a 46% molar yield (92% of the maximum theoretical yield).

  • Publication number: 20210285019
    Abstract: Disclosed herein are methods and compositions for catalytic glycolysis to deconstruct PET to bis(2-hydroxyethyl) terephthalate (BHET). For BHET conversion to terephthalate and ethylene glycol, we engineer Pseudomonas putida KT2440 with PETase and MHETase enzymes from Ideonella sakaiensis. We further engineer P. putida to convert terephthalate to a performance-advantaged bioproduct, ?-ketoadipic acid, and for improved utilization of ethylene glycol, a byproduct of BHET catabolism. In a bioreactor, we produce 15.1±0.6 g/L of ?-ketoadipic acid (?KA) from BHET at 76±3% molar yield. Lastly, we demonstrate conversion of catalytically depolymerized PET to ?KA. Overall, this work highlights the potential of tandem catalytic deconstruction and biological conversion as a means to upcycle waste PET.

  • Publication number: 20210180007
    Abstract: Disclosed herein are engineered P. putida KT2440 co-expressing PETase and MHETase enzymes that selectively degrades PET into monomers, ethylene glycol and terephthalate (TPA). In another embodiment, disclosed herein are methods for making and using a highly efficient EG metabolizing P. putida KT2440 strain. Given that native P. putida does not have a TPA metabolic pathway, nor the proteins to transport TPA into the cell, the next metabolic engineering challenge for developing synthetic P. putida strain to plastic upcycling was enabling TPA catabolism in P. putida KT2440. TPA transporters and catabolic pathway have been characterized in several microorganisms including Comamonas sp. strain E6 and Rhodococcus jostii RHA1.
