  • Publication number: 20230405653
    Abstract: The present invention relates to a method for sanitizing waste, where waste having specific bacterial counts are subjected to an enzyme composition at a pH between 30 and 6.0 and at a temperature of between 40° C. and 60° C., the liquid is separated and the waste is subjected to the enzyme composition for a period of 10 to 30 hours to obtain at least partial reduction in bacterial count.

  • Publication number: 20230405654
    Abstract: The present invention relates to a method for continuous or batch processing of waste, such as municipal solid waste, subject to enzymatic and/or microbial degradation in a bioreactor resulting in a bioliquid and a solid fraction, which method comprises recirculation of process water obtained from downstream processing of said bioliquid and/or solid fraction. Water from external sources may also be added to the reactor in addition to the recirculation of process water.

  • Patent number: 11306331
    Abstract: The present invention generally relates to the field of biotechnology as it applies to the production of hydroxycinnamic acids using polypeptides having tyrosine ammonia lyase activity. More particularly, the present invention pertains to polypeptides having tyrosine ammonia lyase activity and high substrate specificity towards tyrosine, which makes them particularly suitable in the production of p-coumaric acid and other hydroxycinnamic acids. The present invention thus provides processes for the production of p-coumaric acid and other hydroxycinnamic acids employing these polypeptides as well as recombinant host cells expressing same.
