antimicrobial properties of natural phenols and related compounds: obtusastyrene and dihydro-obtusastyrene.	factors influencing the antimicrobial properties of obtusastyrene and dihydro-obtusastyrene were studied. both of these compounds were soluble in acetone, alcohol, and olive oil. in water, they were soluble at concentrations of 34 and 53 mug/ml, respectively. the minimal inhibitory concentrations against gram-positive bacteria and yeast were below 100 mug/ml. the compounds were not effective against gram-negative bacteria at 200 mug/ml or lower concentrations. with initial populations of cells g ...	1972	4625626

tentative method for the qualitative detection and quantitative assessment of air contamination by drugs.	a method for detecting and measuring air contamination by drugs is described which uses an electrostatic bacterial air sampler, sprayers for micronizing drugs, and mueller-hinton medium seeded with a highly susceptible strain of sarcina lutea. three antibiotics (penicillin, tetracycline, aminosidine) and a sulfonamide (sulfapyrazine) were identified by pretreating portions of medium, showing no bacterial growth, with penicillinase or p-aminobenzoic acid solution and subsequently determining how ...	1972	4483536

mechanism of excretion of a bacterial proteinase: demonstration of two proteolytic enzymes produced by a sarcina strain (coccus p).	a sarcina strain (coccus p) produces two proteolytic enzymes. one is found only extracellularly, is far more prevalent, and is actively excreted during exponential growth. it is the enzyme responsible for the known strong proteolytic activity of the cultures of this strain. a second protease is, however, produced which remains associated with the intact cells but is released by the protoplasts. the two enzymes appear unrelated in their derivation. calcium ions play an essential role in preventin ...	1971	5107856
mechanism of excretion of a bacterial proteinase: factors controlling accumulation of the extracellular proteinase of a sarcina strain (coccus p).	it has been known that the extracellular proteinase of coccus p is found only in cultures grown in the presence of ca(2+). it is now shown that this cation is required neither for synthesis, excretion, or activation of a zymogen nor as a prosthetic factor necessary for enzymatic activity. the only function of ca(2+) is to stabilize the active structure of the enzyme molecule, presumably by substituting for absence of s-s bridges. in the absence of ca(2+), the excreted proteinase undergoes rapid ...	1971	5107857

microbial transformation of antibiotics: phosphorylation of clindamycin by streptomyces coelicolor müller.	addition of clindamycin to whole-cell cultures of streptomyces coelicolor müller resulted in the loss of in vitro activity against organisms sensitive to clindamycin. incubation of such culture filtrates with alkaline phosphatase generated a biologically active material identified as clindamycin. fermentation broths containing inactivated clindamycin yielded clindamycin 3-phosphate, the structure of which was established by physical-chemical and enzymatic studies. clindamycin was phosphorylated ...	1971	5166238

therapy of staphylococcal infections in monkeys. vii. comparison of cyclacillin and nafcillin.	intravenous inoculation of a penicillin-resistant phage type 80/81 staphylococcus caused lethal infection in seven of eight untreated monkeys. daily intragastric administration of 50 mg/kg given in two equal morning and afternoon doses of cyclacillin and nafcillin was followed by mortalities of four of four and two of four monkeys, respectively. after 100 mg per kg per day, three of four and one of four monkeys receiving cyclacillin and nafcillin, respectively, died. thus, mortality in controls ...	1971	5002313

cephaloglycin and its biologically active metabolite desacetylcephaloglycin.	chromatographic studies and microbiological assays show that, after oral administration, cephaloglycin is partially converted in man to a biologically active metabolite desacetylcephaloglycin. the antibacterial activity of this metabolite compared to that of cephaloglycin is equivalent against gram-positive organisms but is lower against gram-negative bacilli. successful therapy of urinary tract infections with cephaloglycin must be mainly attributed to the antibacterial activity of this metabol ...	1971	4994901

inhibition of the plaquing efficiency of t4r+ bacteriophage by subtilisin.	the mechanism by which the replicative cycle of t4r(+) phage is inhibited by certain nonhost bacterial systems was investigated. some bacillaceae, especially bacillus subtilis, decreased the plaquing efficiency of this virus more than 95% within 24 hr of exposure. sarcina lutea and micrococcus sp. both failed to cause any significant change in the infectivity of t4r(+) phage. preliminary investigations into the nature of the inhibitory substance(s) suggested that an extracellularly elicited prot ...	1971	4995848

specific assay of aminoglycosidic- or polymyxin-type antibiotics present in human sera in combination with cephalosporins.	monitoring of serum concentrations of aminoglycosidic or polymyxin antibiotics when administered concurrently with cephalosporins or penicillins requires a special assay technique. selective enzymatic degradation of the beta-lactam antibiotic from the serum specimen allows subsequent assay of the antibiotic being monitored. this report gives details of a simple procedure for laboratory production of a crude enzyme capable of degrading cephalosporins or penicillins. an assay procedure for quantit ...	1971	4327609
confirmation of the identification of the major c-29 hydrocarbons of sarcina lutea.	although there is agreement on the fact that sarcina lutea strain fd-533 has branched c-29 monoalkenes as major hydrocarbon components, there is disagreement in the literature as to the nature of the branching. this has been resolved by analyses of the fatty acids produced by permanganate-periodate treatment of each of the resolvable hydrocarbon fractions making up the c-29 complex. the three major components are identified as doubly branched, delta(13) species with two iso terminations, one iso ...	1971	4330736

the effect of high vacuum on oxidative reactions in bacteria and the activity of certain enzymes.	among the physical factors which might influence micro-organisms one of the most potentially interesting is high vacuum. the effect of high vacuum is less studied as compared with other physical factors. it is impossible to achieve, under laboratory conditions, a vacuum of the order 10(-16) mm hg which is probably characteristic of space. earlier, the effect of high vacuum was studied on different bacteria, yeasts, molds and algae. it appeared that spores and fungal conidia were not killed by hi ...	1970	12664921
methods for the determination of deoxyribonucleic acid homologies in streptomyces.	variations of the membrane filter technique for deoxyribonucleic acid (dna) hybridizations were studied with respect to streptomyces species. at the temperatures required for specific hybridization of dna with the high melting temperature (t(m)) characteristic of streptomyces, large amounts (up to 97%) of filter-bound dna became eluted, in all reaction mixtures studied, within 21 hr. in most solutions this leaching was increased by the presence of sheared denatured dna. incubation of dna-loaded ...	1970	16559080
