    Abstract: The present invention relates to certain processes and compositions useful for inhibiting and/or controlling the growth of slime in water and, in particular, water employed for industrial purposes. Water employed in the manufacture of pulp paper and water employed in cooling water systems, as well as other industrial waters, provide environments which are conducive to slime formation. The novel compositions of the present invention are mixtures which show unexpected synergistic activity against microorganisms, including bacteria, fungi and algae, which produce slime in aqueous systems. The slime, of course, is objectionable from an operational and/or an aesthetic point of view. Specifically, the invention is directed to and the use of compositions comprising a combination of 5-chloro-4-phenyl-1, 2dithiole-3-one and organo-bromine compounds (or mixtures thereof). The inventive compositions inhibit the growth of slime in water, or more specifically, possess biocidal activity against bacteria, fungi and/or algae. The organo-bromine compounds contemplated for use in accordance with the present invention may be exemplified by; bis-1, 4-bromoacetoxy-2-butyne; bis-1, 4bromoacetoxy-2-butene; alpha-bromo-p-methylacetophenone and betabromo-beta-nitrostyrene.

    Abstract translation: 本发明涉及用于抑制和/或控制水中，特别是用于工业目的的水中生长的粘土的某些方法和组合物。 用于制造用于冷却水系统以及其他工业水域的纸浆纸和水的水提供有利于粘液形成的环境。 本发明的新型组合物是对含水体系中产生粘液的微生物，包括细菌，真菌和藻类显示意想不到的协同活性的混合物。 当然，泥浆从操作和/或审美的角度来说是令人反感的。 具体地，本发明涉及包含5-氯-4-苯基-1,2-二硫代-3-酮和有机溴化合物（或其混合物）的组合的组合物的用途。 本发明的组合物抑制水中粘液的生长，或者更具体地，其具有对细菌，真菌和/或藻类的杀生物活性。 预期用于本发明的有机溴化合物可以例示为： 双-1,4-溴乙酰氧基-2-丁炔; 双-1,4-溴乙酰氧基-2-丁烯; α-溴 - 对甲基苯乙酮和β-溴-β-硝基苯乙烯。

    Abstract: THE PRESENT DISCLOSURE IS DIRECTED TO A METHOD WITH A TWO-FOLD OBJECTIVE. AS IS WELL KNOWN, PULP MILL WASTES WHICH ARE PRIMARILY COMPOSED OF LIGNIN ARE DARK IN COLOR AND EXTREMELY RESISTANT TO BIODEGRADATION. ACCORDINTLY, THE DISCHARGE OF THESE WASTES TO ANY NATURAL WATERWAYS IS LIMITED BY LEGISLATION. THE PRESENT INVENTION PROVIDES A METHOD FOR IMPROVING THE COLOR CHARACTERISTICS OF THE WASTE AND FOR UTILIZING THE PRODUCT OR MATERIAL OBTAINED THEREBY TO PRODUCE VALUABLE AND UTILIZABLE MATERIALS OR CHEMICALS. BASICALLY, THE METHOD ENTAILS CONTACTING AN OXIDATIVELY TREATED WASTE AND, MORE SPECIFICIALLY, AN OXIDATIVELY TREATED WASTE LIGNIN WITH A MICROBIAL POPULATION FOR A TIME AND AT CONDITIONS NECESSARY TO CONVERT SAID OXIDATIVELY TREATED LIGNIN TO THE UTILIZABLE END PRODUCTS. EXAMPLES OF UTILIZABLE PRODUCTS WHICH CAN BE OBTAINED IN THIS MANNER ARE ORGANIC ACIDS, BIOPOLERS, PROTEINS, ANTINBIOTICS, STEROIDS, VITAMINS, FERTILIZERS, ETC.
