Growth-promoting Activity of Spent Sulfite Liquor

چکیده

The discharge of spent sulfite liquor (SSL), the waste water produced during cellulose manufacture, into water courses often results in massive slime infestations of Sphaerotilus natans. Though a considerable amount of work has been done on the stimulation of Sphaerotilus in mixed populations, the most notable probably being that of Amberg and Cormack (1), very little (6) is known about the nutritional adequacy of SSL for growth of pure cultures of S. natans. Our observations (Bacteriol. Proc., p. 48, 1967) on the calcium requirement of S. natans prompted us to compare the growth-promoting activities of calcium (SSL-Ca) and ammonia (SSL-NH4) base liquors (i.e., liquors derived from processes using the bisulfites of calcium and ammonia, respectively, in the chemical digestion of the wood).

Generation of PHB from Spent Sulfite Liquor Using Halophilic Microorganisms

Halophilic microorganisms thrive at elevated concentrations of sodium chloride up to saturation and are capable of growing on a wide variety of carbon sources like various organic acids, hexose and also pentose sugars. Hence, the biotechnological application of these microorganisms can cover many aspects, such as the treatment of hypersaline waste streams of different origin. Due to the fact th...

Isolation and characterization of acetic acid-tolerant galactose-fermenting strains of Saccharomyces cerevisiae from a spent sulfite liquor fermentation plant.

From a continuous spent sulfite liquor fermentation plant, two species of yeast were isolated, Saccharomyces cerevisiae and Pichia membranaefaciens. One of the isolates of S. cerevisiae, no. 3, was heavily flocculating and produced a higher ethanol yield from spent sulfite liquor than did commercial baker's yeast. The greatest difference between isolate 3 and baker's yeast was that of galactose...

Bioproducts from sulfite pulping : Bioconversion of sugar streams from pulp , sludge , and spent sulfite liquor

The production of singleand mixed-sugar streams and their conversion to bioproducts were studied using sulfite pulping streams as feedstocks. Sulfite pulp, sludge, and spent sulfite liquor (SSL) were utilized because they are concurrently generated alongside of bleached pulp, and because the pulping process renders pretreatment unnecessary. SSL, comprised of mostly monomeric hexose and pentose ...

Adaptation of Scheffersomyces stipitis to hardwood spent sulfite liquor by evolutionary engineering

BACKGROUND Hardwood spent sulfite liquor (HSSL) is a by-product of acid sulfite pulping process that is rich in xylose, a monosaccharide that can be fermented to ethanol by Scheffersomyces stipitis. However, HSSL also contains acetic acid and lignosulfonates that are inhibitory compounds of yeast growth. The main objective of this study was the use of an evolutionary engineering strategy to obt...

Removal of Acetic Acid from Spent Sulfite Liquor Using Anion Exchange Resin for Effective Xylose Fermentation with Pichia stipitis

Acetic acid is one of the major inhibitors of spent sulfite liquor (SSL) fermentation for ethanol production. The objective of this study was to remove acetic acid from hardwood SSL using anion exchange resin in order to achieve effective fermentation with Pichia stipitis CBS6054. Lignosulfonate, as well as sulfate and sulfite ions in the SSL hindered the removal of acetic acid by anion exchang...
