  • Patent number: 10683211
    Abstract: Molasses based alcohol distilleries generate highly contaminated, dark coloured and foul smelling effluent (bio-methanated spent wash, BMSW, also known as post methanated effluent). While the prevailing practices for treatment of alcohol distillery effluents operate on the premises of “liability management”, high potassium content of spent wash (ca. 2% w/v in BMSW) offers an opportunity for its utilisation in production of potash fertilizers—a major agricultural input. The present invention provides process for potash recovery from BMSW with concomitant environmental remediation of effluent. The process involves pre-treatment of BMSW followed by potash recovery through selective precipitation technique to produce potash fertilizers and activated carbon while generating a relatively benign effluent (>80% remediation). It may further be possible for the alcohol distilleries to achieve ZLD status by incorporating commercially practiced water recovery techniques (viz.

  • Patent number: 10036043
    Abstract: The present invention relates to processes for producing ethanol from starch-containing material by liquefying the starch-containing material at a temperature above the initial gelatinization temperature using an alpha-amylase; saccharifying using a glucoamylase and fermenting using a Saccharomyces cerevisiae yeast strain deposited under Accession No. V14/004037 at National Measurement Institute, Victoria, Australia) or a fermenting organism strain having properties that are about the same as that of the deposited Saccharomyces cerevisiae strain or a derivative of Saccharomyces strain V14/004037 having the defining characteristics of strain V14/004037. The invention also relates to a Saccharomyces yeast strain deposited under the Budapest Treaty and having NMI accession no. V14/004037 or a derivative of strain V14/004037 which exhibits one or more defining characteristics of strain V14/004037.

  • Patent number: 10023837
    Abstract: Disclosed herein are materials and methods for creating and/or isolating variants of yeasts especially variants of Saccharomyces cerevisiae that can grow on sugars other than D-glucose in the presence of amounts of 2-deoxy-glucose and or D-glucose that inhibit most strains of yeast from growing on sugars other than D-glucose. Selection media that can be used to isolate such variants include pentose sugars such as D-xylose, L-glutamine and 2-deoxy-glucose. Mutations in the Grr1 and Red genes in some strains also produce variants that can grow on sugars including the pentose D-xylose in the presence of 2-deoxy-glucose.

  • Patent number: 10006057
    Abstract: The present invention relates to materials and methods for the production of ethanol. More particularly, the present invention provides genetically modified strains of Saccharomyces cerevisiae having enhanced tolerance for gamma valerolactone (GVL) toxicity. Also provided are methods of using such genetically engineered yeast strains for improved GVL-mediated hydrolysis of lignocellulosic biomass for industrial-scale ethanol production.

  • Patent number: 10000777
    Abstract: Ear corn is picked from corn fields by ear corn harvesters and transported to a central shelling station associated with an ethanol manufacturing facility. Shelled corn from the central shelling station is processed into ethanol at the ethanol manufacturing facility, and corn cobs from the central shelling station are burned to provide process heat for the ethanol manufacturing process. Energy is conserved and costs are reduced during the picking and shelling of the ear corn and by the burning of cobs for process heat.

  • Patent number: 9994874
    Abstract: The invention relates to a process for the production of alcohols from biomass that comprises a stage in which at least one aqueous internal flow that comprises at least one alcohol that has n carbon atoms, with n between 2 and 5, is recycled, provided that when the alcohol comprises 2 carbon atoms, it is mixed with at least one other alcohol in such a way as to recover a vapor phase effluent that contains alcohols exiting from said pretreatment reactor.
