  • Patent number: 11155838
    Abstract: It is disclosed a process to produce a fermentation product from a ligno-cellulosic feedstock hydrolyzate slurry which comprises water, water soluble glucose and xylose and water insoluble pretreated ligno-cellulosic feedstock. The process comprises at least two conversion step. A first conversion medium comprising a first portion of the ligno-cellulosic feedstock hydrolyzate slurry and a yeast capable to ferment glucose and xylose is first created, then the yeast is allowed to convert at least 50% of the glucose and less than 20% of the xylose of the first conversion medium to a first propagated yeast and a first portion of the fermentation product in a first conversion step having a first sugar-to-cells conversion ratio in a range of from 5% to 25%.

  • Patent number: 11085017
    Abstract: It is disclosed a process for propagating a yeast capable to ferment glucose and xylose of a lignocellulosic feedstock hydrolyzate, said process comprising propagating the yeast over at least two propagation cycles. The first propagation cycle comprises the steps of: contacting the yeast at a starting yeast density with a first cultivation medium comprising a first portion of the lignocellulosic feedstock hydrolyzate; and allowing the yeast to propagate to create a first populated broth comprising water and a first propagated yeast, wherein at least 50% of the glucose and less than 20% of the xylose in the first cultivation medium are consumed in the first propagation cycle.

  • Publication number: 20170252699
    Abstract: In place of a step of centrifugation during preparation of outer membrane vesicles (OMVs) from bacteria, the invention utilises ultrafiltration. This allows much larger amounts of OMV-containing supernatant to be processed in a much shorter time. Thus the invention provides a process for preparing bacterial OMVs, comprising a step of ultrafiltration. The ultrafiltration step is performed on an aqueous suspension of OMVs after they have been prepared from bacteria and the OMVs remain in suspension after the filtration step. The invention is particularly useful for preparing OMVs from Neisseria meningitidis.
