| variation of type-b dna x-ray fiber diagrams with base composition. | eight natural dnas of widely differing base composition have been studied by x-ray diffraction in fibers at high relative humidity. the resulting type b diffraction diagrams showed that all of the dnas had a 34-a pitch and 3.4-a interbase pair separation. however, the intensity distribution on the inner three layer lines was a strong function of the base content. in diffraction diagrams of very at-rich dna, the intensity of the first and third layer line was 2- or 3-times stronger than in the pa ... | 1973 | 4352977 |
| direct evidence of the c-like form of sodium deoxyribonucleate. | from infrared linear dichroism studies, direct evidence is given for a new na dna form, which is similar to the c form of li dna. this c-like form in na dna occurs under conditions of very low nacl content (at high relative humidity), high nacl content (at low relative humidity), and low g + c content of the dna (at low relative humitiy). the c form of li dna was originally discovered by x-ray diffraction, but has not previously been characterized by infrared spectroscopy. the c form is primaril ... | 1973 | 4357868 |

| unusual sulfonolipids are characteristic of the cytophaga-flexibacter group. | capnocytophaga spp. contain a group of unusual sulfonolipids, called capnoids (w. godchaux iii and e. r. leadbetter, j. bacteriol. 144:592-602, 1980). one of these lipids, capnine, is 2-amino-3-hydroxy-15-methylhexadecane-1-sulfonic acid; the others are, apparently, n-acylated versions of capnine. the lipids were found, in amounts ranging from 2.5 to 16 mumol of capnoid sulfur per g of cells (wet weight), in two cytophaga spp. and also in several closely related organisms: several capnocytophaga ... | 1983 | 6298180 |
| sulfonolipids of gliding bacteria. structure of the n-acylaminosulfonates. | earlier (godchaux, w., and leadbetter, e. r. (1980) j. bacteriol. 144, 592-602; (1983) j. bacteriol. 153, 1238-1246) we demonstrated that an unusual class of sulfonolipids are major components of the cell envelope of gliding bacteria of the genus cytophaga and of closely related genera. one of these lipids, to which we have assigned the trivial name capnine, was purified and was shown to be 2-amino-3-hydroxy-15-methylhexadecane-1-sulfonic acid (which might also be named as 1-deoxy-15-methylhexad ... | 1984 | 6321489 |
| biosynthesis of the sulfonolipid 2-amino-3-hydroxy-15-methylhexadecane-1-sulfonic acid in the gliding bacterium cytophaga johnsonae. | the biosynthesis of the sulfonolipid 2-amino-3-hydroxy-15-methylhexadecane-1-sulfonic acid (capnine) was studied by measuring the incorporation of possible precursors into the lipid by cells grown in the presence of precursors which were labeled with stable isotopes. cells grown on yeast extract in the presence of dl-[3,3-2h2]serine contained 40.1 mol% of the protein-bound serine and 5.0 mol% of the protein-bound cysteine derived from the labeled serine. cells grown in the presence of dl-[3,3-2h ... | 1984 | 6330048 |
| a cytophaga species endotoxin as a putative agent of occupation-related lung disease. | a previous study suggested that a biologically active bacterial endotoxin was a putative agent of lung disease in a textile-producing facility. the endotoxin was isolated from the biomass growing in a chilled-water spray air humidification system. the bacterial flora of the air humidification system were isolated and taxonomically identified to the genus level. by using indirect immunofluorescence assays, a serologically reactive cytophaga species was identified. a serologically reactive, biolog ... | 1984 | 6360896 |
| special bacterial polysaccharides and polysaccharases. | alcaligenes faecalis var. myxogenes 10c3, which we isolated from soil, produces a water-soluble and an insoluble extracellular polysaccharide. the former (succinoglycan) is composed of glucose, galactose, pyruvic acid and succinic acid (molar proportions 7:1:1:1) with (beta 1-3)-, (beta 1-4)- and (beta 1-6)-glucosidic linkages. the latter (curdlan) is composed entirely of (beta 1-3)-linked d-glucose and forms a resilient firm gel when heated in suspension. the organism also produces extracellula ... | 1983 | 6400487 |
| [isolation and regeneration of micromonospora olivoasterospora protoplasts]. | the conditions for preparation and regeneration of the protoplasts of m. olivoasterospora were developed. it was found that effective formation of the protoplasts required preliminary cultivation of m. olivoasterospora in the medium containing glycine in a concentration inhibiting its growth at least by 60-80 per cent. the strains studied markedly differed in their sensitivity to glycine and were highly sensitive to it. the efficacy of the protoplast formation depended on the culture age and inc ... | 1984 | 6486752 |
| identification and evolution of the cellulolytic microflora present during composting of cattle manure: on the role of actinomycetes sp. | population changes in cellulolytic microflora were studied during composting of cattle manure. six bacterial and nine actinomycetes species were isolated. among the isolates, two actinomycetes, micromonospora chalcae and pseudonocardia thermophila, were cellulolytic strains which were numerically dominant and might therefore play a notable role in the degradation of cellulose in cattle manure. fungi were practically absent during the process, but two cellulose-degrading bacterial species, sporoc ... | 1984 | 6508072 |
| isolation and characterization of a new cytophaga species implicated in a work-related lung disease. | a yellow-pigmented, gram-negative, gliding bacterium isolated from an industrial water spray air humidification system was implicated as a causative agent in several occurrences of lung disease with hypersensitivity pneumonitis-like symptoms. the bacterium, designated wf-164, lacked microcysts or fruiting bodies and had a dna base composition of 34.8 mol% of guanine plus cytosine. gliding, flexing, nonflagellated cells measuring 0.3 by 3.5 to 8.9 micron were observed by using light and electron ... | 1984 | 6508308 |
| evidence for the participation of n-acetylated amino sugars in the coaggregation between cytophaga species strain dr2001 and actinomyces israelii pk16. | coaggregation between cytophaga sp. strain dr2001 and actinomyces israelii pk16 was partially inhibited by certain n-acetylated amino sugars (n-acetylneuraminic acid, n-acetylgalactosamine, and n-acetylglucosamine) and was completely inhibited by the trisaccharide neuraminin-lactose. the monosaccharides exerted their effect at concentrations between 30 to 100 mm, whereas the trisaccharide was an effective inhibitor at significantly lower concentrations. outer membrane preparations caused a. isra ... | 1984 | 6715035 |
| isolation and characterization of nonspreading mutants of the gliding bacterium cytophaga johnsonae. | three approaches were taken to isolate a total of 153 nonspreading mutants derived from our laboratory strain of cytophaga johnsonae, uw101, or from its auxotrophic derivative, uw10538. characterization of 109 of these mutants led to their placement in five general categories: (i) motile, nonspreading (mns) mutants whose cells are motile to various degrees but whose colonies fail to spread on agar gels under any conditions of incubation; (ii) conditional nonspreading (cns) mutants with motile ce ... | 1984 | 6735983 |
| trail following by gliding bacteria. | slime trails, which are deposited on surfaces by gliding bacteria and which serve as preferential pathways for gliding motility, were tested for the species specificity of their support of movement. among the pairs of bacteria tested, a variety of gliding bacteria and a flagellated bacterium moved along trails of unrelated species. thus, the trails did not serve as pheromones. rather, they may have guided gliding elasticotactically. some biological implications of this finding are considered. | 1982 | 6811562 |
