摘要： The disclosure relates to bioreactors, for example for biological treatment and, more specifically to bioreactor insert apparatus including biofilms and related methods. The bioreactor insert apparatus provides a means for circulation of reaction medium within the bioreactor, a biofilm support, and biological treatment of an inlet feed to die reactor/insert apparatus. The bioreactor insert apparatus has a high relative surface area for biofilm attachment and is capable of generating complex flow patterns and increasing treatment efficiency/biological conversion activity in a biologically-active reactor. The high surface area structure incorporates multiple biofilm support structures such as meshes at inlet and outlet portions of the structure. The biofilm support structures and biofilms thereon can increase overall reaction rate of the bioreactor and/or perform some solid/liquid separation in the treatment of the wastewater or other influent.

摘要： A method for improved anaerobic digestion is presented. The method includes mixing a volume of waste material with water to form a feedstock mixture. The volume of waste material includes an initial amount of biomass and the feedstock mixture includes methanogenic bacteria either naturally present in the waste material or introduced artificially. The method also includes introducing one or more promoter substances to the feedstock mixture. The one or more promoter substances are capable of modifying the methanogenic bacteria. Modifying includes stimulating novel enzyme production in the methanogenic bacteria.

摘要： It has been found that wild-type ferulic acid decarboxylase derived from Saccharomyces has high catalytic activity for the production of unsaturated hydrocarbon compounds. Further, it has been found that in the ferulic acid decarboxylase, substitute of the amino acid at position 398 with glutamine, methionine, asparagine, phenylalanine, histidine, or threonine more improves the catalytic activity, making it possible to provide a method capable of producing an unsaturated hydrocarbon compound such as butadiene with high productivity, and an enzyme used in the method.

摘要： Provided are an anaerobic immobilized bacterial agent, a preparation method for same, and applications thereof. The preparation method for the bacterial agent is: selecting four different anaerobic functional bacterial strains, utilizing a pure bacteria culturing technique to produce corresponding culture broths, then mixing the four culture broths according to a certain volume ratio to acquire a compound functional broth, subsequently concentrating into a functional flora precipitation, then dissolving the functional flora precipitation into a polyvinyl alcohol aqueous solution, dripping the solution into a first buffer solution to produce polyvinyl alcohol gel beads, and placing the gel beads produced into a second sulfate-containing buffer solution to produce sulfate-modified polyvinyl alcohol gel beads, that is, the anaerobic immobilized bacterial agent.

摘要： The present disclosure relates to recombinant microorganisms having an improved ethylene producing ability, methods of producing the same, and methods of producing ethylene. A benefit of the recombinant microorganisms and the methods disclosed herein can include increased production of ethylene from microbial cultures. An additional benefit can be the use of carbon dioxide to produce bio-ethylene useful as a feedstock for the production of plastics, textiles, and chemical materials, and for use in other applications. Another benefit of the methods and systems disclosed herein can include reduction of excess carbon dioxide from the environment.

摘要： An active solid state fermentation bioreactor for producing gases, liquid(s) or solids from gaseous or gaseous and liquid starting materials and a fermentation process using the reactor are disclosed, The bioreactor includes three major phases; a solid phase including the porous solid support, a liquid phase comprising liquid, and a gaseous phase. The solid phase includes a porous solid support, in which at least 20% of the pore volumes have a size resulting in a liquid suction of about 0.01 to about 0.1 bars if these pores are filled with liquid, the porous solid support is inoculated with desired micro-organisms, the volume of the gaseous phase is 20% to 60% of the volume of the bioreactor, and the liquid phase is at least 20% of the reactor volume, The unsaturated capillary conductivity of filling/packing solid material of the bioreactor is at least 0.1 cm/ h. The solid state fermentation bioreactor enables a large gas-liquid interface, in which the filling material has a good capillary conductivity despite the unsaturated state.
