| microbial fouling of reverse-osmosis membranes used in advanced wastewater treatment technology: chemical, bacteriological, and ultrastructural analyses. | biofouling of reverse-osmosis membranes was investigated at an advanced wastewater treatment facility. cellulose diacetate membranes operated for approximately 4,000 h became uniformly coated with a mucilaginous fouling layer. the fouling material was approximately 93% water by weight, and nearly 90% of the dehydrated residue was organic in composition. calcium, phosphorous, sulfur, and chlorine were the major inorganic constituents detected. protein and carbohydrate represented as much as 30 an ... | 1983 | 6847180 |
| microorganisms of the san francisco sour dough bread process. ii. isolation and characterization of undescribed bacterial species responsible for the souring activity. | a medium was developed which permitted isolation, apparently for the first time, of the bacteria responsible for the acid production in the 100-year-old san francisco sour dough french bread process. some of the essential ingredients of this medium included a specific requirement for maltose at a high level, tween 80, freshly prepared yeast extractives, and an initial ph of not over 6.0. the bacteria were gram-positive, nonmotile, catalase-negative, short to medium slender rods, indifferent to o ... | 1971 | 5553285 |
| detection of blastocystis from stool samples using real-time pcr. | we developed a real-time lc pcr assay to detect a 152 bp sequence in an uncharacterized region of the blastocystis genome. the described assay detected 11 of 11 atcc strains of blastocystis from subtypes 1, 3, and 4. three of three stool samples from oregon and california military personnel that were negative for blastocystis by an ova and parasite test as well as a conventional pcr assay were positive for blastocystis using our real-time lc pcr assay. diagnosis of blastocystis infections using ... | 2008 | 18488250 |
