Disclosed herein are compositions comprising polysaccharide particles with an average size of about 0.1-10 mm. These particles comprise at least (i) about 50%-90% by weight water or an aqueous solution, and (ii) about 10%-50% by weight insoluble alpha-glucan, or an insoluble cationic ether thereof, comprising alpha-1,3-glycosidic linkages and having a weight-average degree of polymerization (DPw) of at least about 100. Further disclosed are methods of preparing these compositions, as well as systems for storing and/or moving them.

Flowable bulk granular polysaccharide

Flowable bulk granular alpa-glucan

Methods are provided for pelletizing a microbial biomass, extracting a refined lipid composition from the pelletized biomass under supercritical conditions and distilling the refined lipid composition, at least once under short path distillation conditions, to obtain a lipid-containing fraction. Also disclosed are methods of making lipid-containing oil concentrates therefrom, by transesterifying and enriching the lipid-containing fraction.

Method for obtaining a lipid-containing composition from microbial biomass

The disclosure provides a paper slurry comprising a treated inorganic pigment, wherein the treated inorganic pigment comprises an inorganic pigment comprising a pigment surface area of about 30 to about 75 m/g; wherein the pigment surface is treated with an organic treating agent comprising a polyalkanol alkane or a polyalkanol amine, present in the amount of at least about 1.5%, and wherein the treated inorganic pigment has a RHI (rat hole index) of about 7 to about 11.

Treated inorganic pigments having improved bulk flow and their use in paper slurries

The invention provides a treated powder having improved loose bulk density comprising a silanized inorganic powder treated with a long chain fatty acid or salts thereof, wherein the amount of the long chain fatty acid is about 0.25% to about 2 wt %, based on the total weight of the treated powder.
