The growth, physiology and intermediary metabolism of bacillus stearothermophilus.
… cycle was present in vegetative cells of B. stearothermophilus, and to understand the effects of growth conditions on the carbohydrate metabolism and cytochrome content of the organism. In order to study the intermediary metabolism, the activities of key metabolic enzymes, the products of …

Identifizierung und Charakterisierung eines Vsr-Homologen aus Bacillus stearothermophilus
… Methode wurde zur Identifizierung eines Gens aus Bacillus stearothermophilus H3 angewandt, welches ein Homologes der Vsr-Endonuklease aus Escherichia coli kodiert. Vsr-Endonuklease aus Escherichia coli initiiert die Reparatur von Schäden an 5-Methylcytosin. Die Desaminierung in dsDNA erzeugt eine …

Structure and Molecular Biology of the Pyruvate Dehydrogenase Complex from Bacillus stearothermophilus
… from the thennophilic, Gram-positive bacterium Bacillus stearothermophilus is assembled around a core of 60 copies of the dihydrolipoamide acetyltransferase (E2p) component, organized with icosahedral symmetry. The peripheral subunits, attached to this inner-core, are dihydrolipoamide …

Effect of processing parameters on the detection of animal drug residues in milk
… evaluated for penicillin detection were Bacillus stearothermophilus disk assay, a HPLC described by Barker et al., Charm II microbial receptor assay, and CITE Probe and LacTek enzyme immunoassays. The procedures evaluated for sulfonamide detection were an HPLC method described by Long et …

Duration of Antibiotic Residues in Milk from Cows Treated via Intrauterine and Intramammary Infusion
… from milk containing antibiotic residues. The Bacillus subtilis overnight disc assay method remains as the method of choice for monitoring antibiotic residues in producers' raw milk. The FDA recommends the Sarcina lutea cylinder plate method for determination of penicillin concentration in dry …

Characterization of Amino Acid tRNA Ligases using the Analytical Ultracentrifuge
… from E. coli, AsnRS, LysRS, SerRS and ValRS from Bacillus stearothermophilus. The quaternary structures of ValRSs from S. cerevisiae and B. stearothermophilus are both monomeric (the α-type), whereas all the other aaRSs are homodimers (the α2-type). Two of the aaRS-enzymes have also been …

X-Ray crystal structure of a ribosomal protein S6, S15, S18 : rRNA complex from T. thermophilus, and investigation of conformational changes in 16S rRNA fragments from B. stearothermophilus during ribonucleoprotein assembly
… junctions in separate model systems from Bacillus stearothermophilus. Helix 21 and helix 23 are shown to stack coaxially onto each end of helix 22 in the absence of either S15 or divalent magnesium ions. S15 and magnesium are both shown to stabilize a reorganization of the helix 20, helix …

Effectiveness of on-farm screening tests for detection of antibiotic residues and control of mastitis through antibiotic therapy based on somatic cell counts
… post treatment and tested for residues by the Bacillus stearothermophilus Difco disc assay, the Delvotest-P, and the Penzyme test. Urine of cull cows was collected and tested with the Live Animal Swap Test (LAST). Results showed 21% to 24% of milk samples contained antibiotic residues past the …

Investigation of storage polysaccharide metabolism in lactic acid bacteria
… einige Gram-positive Spezies aus der Gattung Bacillus und Clostridium und den Milchsäurebakterien zwei Gene (glgC und glgD) besitzen. Sie kodieren für Proteine, die der ADP-Glc PPase ähnlich sind. Es wurde dokumentiert, dass GlgC und GlgD die Untereinheiten eines α2β2-Typ heterotetrameren …
