Growth-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 کاملThe soil perfusion technique for the biological degradation of sulfite waste liquor.
Considerable attention has been given to chemical methods of reducing the Biochemical Oxygen Demand (B.O.D.) of semi-chemical neutral sulfite waste (S.N.W.). Very little study has been devoted to a biological method. The exact composition of this paper industry waste will vary with the type of wood chip used and the modification of cook. Table 1 shows a typical composition of the liquor resulti...
متن کاملBioproducts 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 ...

group-oxyheme interaction energy being RT ln ,3 = 820 cal./mole. The total oxyheme-oxyheme interaction energy is about 6000 cal./mole, and the total acid group-oxyheme interaction energy is about 6600 cal./mole. The none too exact experiments on the carbon monoxide equilibrium and the carbon monoxide-oxygen balance of hemoglobin suggest that the interactions a and ,B are effective for carboxyhe...
متن کاملDiscovery of Cellulose as a Smart Material
The past 10 years has witnessed a renewed interest in cellulose research and application, sparked mostly by technological interests in renewable raw materials and more environmentally friendly and sustainable resources. In this paper, we further expand the current knowledge in cellulose applications and technologies by reporting our discovery of cellulose as a smart material that can be used fo...
