    Abstract: The invention is directed to a process for producing a formaldehyde-treated starch. A material which provides ammonium or amine groups is provided in a slurry of formaldehyde-treated starch containing free or unreacted formaldehyde at a pH of above about 6.5. The material combines with the free or unreacted formaldehyde and thus reduces vaporization of the formaldehyde.

    Abstract: GRANULAR CYANOETHYL STARCHES HAVING BELOW ABOUT 0.06 CYANOETHYL GROUPS PER ANHYDROGLUCOSE UNIT ARE READILY GELATINIZABLE IN WATER AT A NEUTRAL PH, SHOW LESS SLUDGE FORMATION ON STORAGE THAN AQUEOUS PASTES OF UNTREATED STARCH, HAVE LESS TENDENCY TO RETROGRADE WHEN PASTED IN WATER, AND ARE MORE READILY LIQUEFIED BY ALPHA-AMYLASE THAN UNTREATED STARCH.

    Abstract: The disclosure is directed to the production of the enzyme glucoamylase. During the growth of glucoamylase producing microorganisms, ammonium hydroxide or ammonia gas is introduced into the growth medium to provide a source of ammonia and to maintain the pH of medium at the level where optimum growth of the microorganisms occurs.
