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 ...
متن کاملGrowth-promoting Activity of Spent Sulfite Liquor
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 nut...
متن کاملSpent Sulphite Liquor for Cultivation of an Edible Rhizopus Sp
Spent sulphite liquor, the major byproduct from the sulphite pulp production process, was diluted to 50% and used for production of an edible zygomycete Rhizopus sp. The focus was on production, yield, and composition of the fungal biomass composition. The fungus grew well at 20 to 40°C, but 32°C was found to be preferable compared to 20 and 40°C in terms of biomass production and yield (maximu...
متن کاملGeneration 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...
متن کاملBinding and desulfurization characteristics of pulp black liquor in biocoalbriquettes.
To control pollutant emissions from coal combustion in some developing countries, biocoalbriquette, an artificially produced solid fuel, was developed. Both the breaking strength and production costs of the biocoalbriquette have become essentially the most important factors in popularizing it in these countries. To increase the breaking strength and decrease the production costs, it is proposed...
