| effect of temperature on the growth and cell wall chemistry of a facultative thermophilic bacillus. | the morphology and cell wall composition of bacillus coagulans, a facultative thermophile, were examined as a function of growth temperature. the morphology of the organism varied when it was grown at different temperatures; at 37 c the organism grew as individual cells which increased in length with increasing growth temperature. at 55 c it grew in long chains of cells. cell wall prepared from cells grown at 37 c contained 44% teichoic acid by weight, whereas cells grown at 55 c contained 29% t ... | 1974 | 4129996 |
| large-scale recrystallization of the s-layer of bacillus coagulans e38-66 at the air/water interface and on lipid films. | s-layer protein isolated from bacillus coagulans e38-66 could be recrystallized into large-scale coherent monolayers at an air/water interface and on phospholipid films spread on a langmuir-blodgett trough. because of the asymmetry in the physiochemical surface properties of the s-layer protein, the subunits were associated with their more hydrophobic outer face with the air/water interface and oriented with their negatively charged inner face to the zwitterionic head groups of the dipalmitoylph ... | 1993 | 8478338 |
| growth of bacillus coagulans in chemically defined media. | a nutritional study was made of five strains of bacillus coagulans obtained from various culture collections. these five strains were descendants of two original isolates; three had been derived from one parent culture in years past and the other two were transfers from another parent culture. therefore, the five cultures should have represented two distinct groups of genetically identical cultures. three of the strains obtained from one culture collection had become methyl red-negative and sorb ... | 1967 | 6035259 |

| rapid purification, partial characterization, and antimicrobial spectrum of the bacteriocin, pediocin acm, from pediococcus acidilactici m. | the bacteriocin from pediococcus acidilactici m, designated as pediocin acm, was rapidly purified to homogeneity by the ph mediated cell adsorption-desorption method and semi-preparative reversed-phase hplc. the purification yield was 40.4% and the specific activity was increased by 2450-fold. it gave a single band and a single peak on sds-page and hplc analysis, respectively. when subjected to electrospray lc-ms analysis, the protein was found to be highly pure and the molecular weight was dete ... | 1997 | 9237116 |
| production, purification and characterization of bacillus lipase. | the lipolytic activities in the supernatant fractions of bacillus cereus and bacillus coagulans cultures were investigated. aeration, agitation, different media, emulsified oils, inoculum size and phase of growth affected lipase production. aeration was essential for lipase production (air: medium ration 4:1) and produced the highest activity. the lipolytic activity reached a maximum level after incubation for two days with continuous agitation. it was also elevated by the presence of either oli ... | 1997 | 9265771 |
| molecular symmetry of glyceraldehyde-3-phosphate dehydrogenase from bacillus coagulans. | the thermolabile glyceraldehyde-3-phosphate dehydrogenase from the facultative thermophile bacillus coagulans has a crystallographically exact 2-fold rotation axis of symmetry in one of its orthorhombic crystal forms (lee et al., 1982). using various crystallographic techniques, we have now identified this axis to be the molecular r-axis, which is the symmetry axis that relates the two subunits that form each active site of the tetrameric enzyme. this is in contrast to the symmetry of the human ... | 1983 | 6631958 |

| prolyl aminopeptidase is not a sulfhydryl enzyme: identification of the active serine residue by site-directed mutagenesis. | prolyl aminopeptidase (pap) has been classified as a sulfhydryl enzyme on the basis of its high sensitivity to p-chloromercuribenzoate and heavy metals. recently, however, the possibility of pap being instead a serine enzyme has been raised as a result of two observations--the conservation of some residues among the paps hitherto sequenced, and a similarity to some serine hydrolases. this is the first report describing an attempt to identify the active residue by site-directed mutagenesis. the p ... | 1994 | 7896753 |
