chromosomal location of thymine and arginine genes in escherichia coli and an f' incorporating them.ishibashi, masahide (osaka university, osaka, japan), yoshinobu sugino, and yukinori hirota. chromosomal location of thymine and arginine genes in escherichia coli and an f' incorporating them. j. bacteriol. 87:554-561. 1964.-the gene responsible for thymine requirement or independence in escherichia coli k-12 is located on the chromosome, near arg(2) (arginine) and between sm (streptomycin) and ade (adenine). a new f' (called f(15)) carrying the thy (thymine) gene as well as the arg(2) gene was ...196414127570
stimulation of carotenogenesis by microbial cells.spent mycelia of blakeslea trispora recovered from a previous fermentation enhanced carotene production by mated cultures of the same organism. peak yields of 107 to 142 mg of carotene per 100 ml of medium were achieved in 6 days. beta-carotene constituted 92% of the total carotenoids produced. the enhancing substance was found present in an aqueous extract of the mycelium. part of its activity was due to an organic acid fraction. other microbial cells, molds, yeasts, and bacteria were also capa ...196414131364
prodigiosin-producing bacteria from marine sources.two aerobic, gramnegative, red-pigmented, rod-shaped bacteria were compared morphologically and physiologically with serratia species, which they resembled superficially. the pigment produced by the marine isolates was shown to be similar to prodigiosin, the red pigment of s. marcescens. the isolates had a single polar flagellum, were oxidative, and did not produce acetoin from glucose or reduce nitrates, which made them distinct from both s. marcescens and s. marinorubra. the latter conformed w ...196414106932
single-stage impaction device for particle sizing biological aerosols.a single-stage impactor device, capable of fractionating a bacterial aerosol into its component mass size classes while preserving the viability of sensitive vegetative cells against the deleterious effects of desiccation and impaction, is described. among the valuable features of the impactor are its negligible wall loss, ease of fabrication and use, and relative inexpensiveness.196414106937

(walter reed army medical center, washington, d.c.), and w. e. farrar, jr. nature of the endotoxin-inactivating principle in guinea-pig liver. j. bacteriol. 87:832-837. 1964.-guinea-pig liver preparations inactivate serratia marcescens endotoxin as assayed in chick embryo. the activity is optimal at ph 6.5 to 7.0 and 8.5 to 9.0. mitochondria and the supernatant fraction containing microsomes possess activity. mitochondria are only active at the acid ph optimum. the activity of acet ...196414137621
interferon reduction in chickens injected with brucella abortus.intravenous injection of large numbers of live, virulent brucella abortus in chickens resulted in the appearance in the serum of a viral inhibitor indistinguishable from interferon. inhibitor was detected as early as 3 hours after inoculation of brucellae and reached a peak between 6 and 12 hours.196414137938
6-aminopenicillanic acid: inhibition of destruction of cephalosporin c by bacteria.6-aminopenicillanic acid, from which all the true penicillins are derived, inhibits the destruction of cephalosporin c by certain microorganisms. this inhibition is probably specific for "cephalosporinase." the enzymatic deacetylation of cephalosporin c is not affected by the acid.196414107444

calibration of a modified andersen bacterial aerosol sampler.a study of the flow regime in the commercial andersen sampler revealed defects in the sampling of the larger airborne particles. satisfactory sampling was obtained by redesigning the hole pattern of the top stages and adding one more stage to extend the range of the instrument. a new, rational hole pattern is suggested for the lower stages. with both patterns a special colony-counting mask can be used to facilitate the assay. a calibration of the modified system is presented which enables partic ...196414106938

influence of temperature on bacterial infection of the hen's egg.temperature of incubation had a marked effect on infection of eggs in which the air cells had been inoculated with a washed suspension of serratia marcescens. there was no evidence of bacterial multiplication or spoilage in eggs held at 10 c for 42 days. multiplication occurred in the shell membranes of eggs held at 30 or at 37 c when the yolk made contact with these membranes, and continued in the contents of the egg, at which time the first signs of spoilage appeared. in a few eggs, very large ...196514325275
