METHOD OF SEPARATING ACIDS AND SUGARS RESULTING FROM STRONG ACID HYDROLYSIS
METHOD OF USING YEAST TO RECOVER PHYTIN BY PRECIPITATION FROM CORNSTEEP LIQUOR OR LIGHT STEEP WATER
Farone William A; Cuzens John E h'vine, CA, UNITED STATES Assigned to Arkenoi lnc A economically viable method for producing sugars using concentrated acid hydrolysis of biomass containing cellulose and hemicellulose is disclosed. The cellulose and hemicelluiose in the biomass is first decrystallized and then hydrolyzed to produce a hydrolysate containing both sugars and acid. Sifica present in the biomass can then be removed for further processing. The remaining solids are then subjected to a second decrystallization and hydrolyzation to optimize the sugar yields. An improved method for separating the sugars from the acid in the hydrolysate is also disclosed. The resulting sugar stream can then be fermented, using an improved method which allows both hexose and pentose sugars to be fermented simultaneously.
l e e Youl-Lark; Park Sang-Jae Seoul, REPUBLIC OF KOREA Assigned to Doosan Technical Center A process for recovery of phytin with a higher purity comprises the steps of preparing LSW or CSL, inoculating a yeast into LSW or CSL culturing the yeast therein to precipitate phytin and separating phyim by sedimentation. The method may comprise a further step of adding salt into CSL to accelerate the formation of phyfin precipitate and increase the yield of phytin.

5580763 METHOD FOR FERMENTATION PRODUCTION OF XANTHAN GUM Honma Taira; Nagura Shigehiro; Murofushi Kanji Jyoetsu, JAPAN Assigned to Shin-Etsu Chemical Co Ltd; Shin-Etsu Bio Inc A method for the fermentation production of xanthan gum which comprises the step of car~ing out culture by using a water-soluble inorganic nitrogen component alone as the nitrogen source of a production medium, and by mixing and using the water-soluble inorganic niCvgen ~ t and a water-insoluble organic nilrogen component as the nitrogen sources of a seed fermentation medium.
METHOD OF MANUFACTURING SUGARS BY TREHALASE Kitahata Sumio; Nakano Hirofum; Washino Tsutom; Moriwaki Masamitsu Osaka, JAPAN Assigned to San-Ei Gen F F I; Osa
Novel trehalase having the properties that it hydrolyzes alpha,alpha'-lrehalose,2,2'-dideoxyalpha, alpha'-trehalose and 2-deoxy- alpha, alpha'-trehaiose into the respective constituting sugars while it does not act on neotrehalose, lactose, maltose, celobiose and sucrose; its optimum pH is 5 to 6; its optimum temperature is 65°C: it is stable against heating up to 65°C; its molecular weight as me~ured by a gel filtration is 400,000 to 500,000 while the molecular weight of the subunit as measured by a sodium dodecylstdfate-polyacrylmnide gel electrophoresis is 180,000 to 250,000; its isoelectric point as measured by an iscelectricfocusingis 2.7;and it is a glycoprotein.
