Embodiments of the present application relate to compositions bupivacaine multivesicular liposomes (MVLs) prepared by a commercial manufacturing process with large particle diameter span.

Separation methods and systems for converting high concentrations of animal wastes into nutrients and other useful products such as struvite and potassium struvite. Advantageously, the system and methods do not require the addition of external chemicals other than an acid and a base.

Algae harvesting and cultivating systems and methods for producing high concentrations of algae product with minimal energy. In an embodiment, a dead-end filtration system and method includes at least one tank and a plurality hollow fiber membranes positioned in the at least one tank. An algae medium is pulled through the hollow fiber membranes such that a retentate and a permeate are produced.

Provided is a fresh water generation system which filters biotreated water produced by microbiologically treating waste water via a primary semi-permeable membrane (8), and then mixes concentrated water rejected by the filtration with seawater, thereby to filter the mixed water via a secondary semi-permeable membrane (14). This system enables frequencies of chemical cleaning and replacement of the secondary semi-permeable membrane to be reduced. The fresh water generation system comprises: a primary semi-permeable membrane apparatus (9) which separates microorganism treating waste water into permeated water and concentrated water; a secondary semi-permeable membrane apparatus (13) which filters mixed water prepared by mixing the concentrated water into seawater. In the fresh water generation system, the primary semi-permeable membrane (8) has an equal to or a higher microorganism adhesive property than the secondary semi-permeable membrane (14).

The present invention relates to a method for separating biomass from a solution comprising biomass and at least one oligosaccharide.comprising providing the solution comprising biomass and oligosaccharides.lowering the pH value of the solution below 7 by adding at least one acid to the solution comprising biomass and the at least one oligosaccharide. adding an adsorbing agent to the solution comprising biomass and oligosaccharides. and carrying out first membrane filtration so as to separate the biomass from the solution comprising the at least one oligosaccharide.

Disclosed herein are systems and methods of extracting a high protein food product from legumes comprising: milling a supply of legumes to form a fine powder; hydrating the fine powder to form a liquid slurry; separating solids from the liquid slurry to form a milk-like fluid; pasteurising said milk-like fluid to remove unwanted organisms therefrom; filtrating said pasteurised milk-like fluid to remove permeates therefrom to form a substantially liquid product; and removing most of the moisture from the substantially liquid product to generate a high protein food product in the form of a powder.

Embodiments of the present application relate to commercial manufacturing processes for making bupivacaine multivesicular liposomes (MVLs) using independently operating dual tangential flow filtration modules.

The invention concerns native whey protein for use in the treatment and/or prevention of intestinal infection or inflammation, in particular necrotizing enterocolitis. The inventors found that native whey protein provides a beneficial effect on intestinal infection or inflammation.

The present invention discloses a mixture of fucosylated chondroitin sulfate oligosaccharides having an average molecular weight between 2700 Da and 3600 Da, in which 90% of total components has a molecular weight between 1800 Da and 5400 Da. The mixture of fucosylated chondroitin sulfate oligosaccharide of the present invention has very low anti-FIIa factor activity, very low anti-FXa factor activity, very high anti-FXase factor activity, i.e., having a significant activity in selectively inhibiting intrinsic FXase, and a significant antithrombotic activity and no risk of bleeding and hypotension that are proved through animal experiments. The present invention also discloses a method for rapidly producing fucosylated chondroitin sulfate oligosaccharides by using sea cucumber as raw material, and the method includes: intercepting and concentrating crude polysaccharide with a membrane, deacetylation with hydrazine, pyrolysis with nitrous acid, reduction with sodium borohydride, membrane separation, etc., achieving rapid preparation and high yield.
