  • Publication number: 20160108448
    Abstract: Fungal glucoamylases from Aspergillus fumigatus that are expressed in Trichoderma reesei host cells (AfGATR) are provided. AfGATRs, including AfGA1TR and AfGA2TR, exhibit high activity at elevated temperatures and at low pH, so AfGATRs can be used efficiently in a simultaneous liquefaction and saccharification process in the presence of alpha amylase, such as Aspergillus kawachii alpha-amylase (AkAA). This greatly reduces the combined run time of liquefaction and saccharification reaction, where the pH and temperature must be readjusted for optimal use of the alpha-amylase or glucoamylase.

  • Patent number: 4077411
    Abstract: Apparatus for aiding eye corneal tissue transplant including a "Teflon" base with a flat platform and a central semispherical post to which a ring or rings are spring-loaded to secure the donated corneal tissue from storage. The post has a fitting for receiving a liquid injector such as a hypodermic syringe and the fitting connects to a vertical conduit in the post that discharges at the top of the post beneath the position of the donor tissue on the post. Before the tissue is secured to the post a biologically harmless liquid is introduced into the conduit from the syringe to part the tissue from the post and protect the delicate underside or endothelium layer of the corneal tissue during the trephining of the transplant "button" from the secured donor tissue.
