A fermentation process includes contacting a starch hydrolysate with a glucoamylase with agitation. And allowing for settling to form a multi-phase solution. A first phase of the multi-phase solution includes a saccharide component comprising about 30 wt % to about 80 wt % (e.g., 30 wt % to 70 wt %, 30 wt % to 60 wt %) based on a total carbohydrate present. The method further includes draining the first phase to isolate the first phase from a second phase to form a fermentation broth comprising a first portion of the first phase. The method further includes fermenting the fermentation broth until a concentration of glucose in the fermentation broth is 40 g/L or less. The method includes adding a second portion of the first phase to the fermentation broth to maintain a concentration of glucose in a range of from about 1 g/L to about 20 g/L in the fermentation broth.

Containment and facility systems for offshore porous floating bioreactors that contain algae water slurries in saltwater environments. A containment system may include a containment boom system, a containment silt curtain system, a containment marineworks system, or a combination thereof. Facility systems include an offshore porous floating bioreactor in fluid communication with at least an onshore algae harvesting system. Algae cultivation may occur at an onshore algae cultivation system or within a porous floating bioreactor, and algae lipid production occurs within a porous floating bioreactor. The lipid induced algae is received by the onshore algae harvesting system for further processing.

Culturing S. glucoliberatum PABB004 under conditions effective for the S. glucoliberatum PABB004 to secrete simple sugars into culture medium. In one or more embodiments, the conditions include a pH of 6.0 to 8.5. In some cases, the culture can include a second organism. A co-culture includes S. glucoliberatum PABB004 and a second organism, wherein the co-culture has a pH of 6.0 or greater. In one or more embodiments, the second organism is selected to produce a product of interest such as, for example, ethanol.

The present invention relates generally to the field of recombinant fatty acid synthesis, particularly in transgenic plants. The application describes genes involved in fatty acid synthesis and provides methods and vectors for the manipulation of fatty acid composition of plant oils. In particular, the invention provides constructs for achieving the integration of multiple heterologous genes involved in fatty acid synthesis into the plant genome, such that the resulting plants produce altered levels of polyunsaturated fatty acids. Also described are methods for enhancing the expression of fatty acid biosynthesis enzymes by co-expressing a silencing suppressor within the plant storage organ.

The method of producing a lipid composition comprises an extraction treatment step to extract a lipid comprised in a hydrated raw material by using an extraction solvent comprising a polar solvent and a nonpolar solvent, and a separation treatment step to separate an extract solution obtained in the extraction treatment step into a polar solvent phase comprising a first lipid fraction and a nonpolar solvent phase comprising a second lipid fraction.
