  • Processes Using Antibiotic Alternatives In Bioethanol Production
    Publication number: 20150118726
    Abstract: Methods for controlling the growth of bacteria in ethanol fermentation systems with antibiotic alternatives, which can be nonoxidizing biocides, stabilized oxidizers, or any combinations thereof, are described. As an option, a process or composition of the present invention can include one or more polycyclic antibacterial peptides. The methods can provide improvements, such as increased ethanol yields with minimal carryover of biocide into co-products of the processes.
    Type: Application

  • Methods For Enhancing Paper Strength
    Publication number: 20140116635
    Abstract: Methods of making paper or paperboard having enhanced dry strength are provided. An enzyme and a polymer including at least one of a cationic water-soluble polymer and an amphoteric water-soluble polymer can be added to a papermaking pulp to yield a treated pulp. The treated pulp can then be formed into paper or paperboard having a dry strength greater than paper or paperboard formed from papermaking pulp without the addition of the enzyme and polymer. Any suitable enzyme can be used, for example, a laccase or a cellulase. Any suitable polymer can be used. For example, at least one of a glyoxylated polyacrylamide (gPAM), a polyvinylamine, a decarboxylated polyacrylamide, and a dimethylamine-epichlorohydrin (epi-DMA).
