cell-free biosynthesis of arphamenine a.arphamenine a was synthesized in a cell-free system obtained from the arphamenine-producing strain, chromobacterium violaceum bmg361-cf4. l-[14c]-phenylalanine was converted to beta-phenylpyruvic acid by phenylalanine amino-transferase obtained from the 10,000 x g supernatant (s10 fraction). [14c]-benzylmalic acid was synthesized from beta-phenylpyruvic acid with [14c]-acetyl-coa in the s10 fraction. [14c]-benzylsuccinic acid was formed from beta-phenylpyruvic acid with [14c]-acetyl-coa and atp ...19863707594
first case report from argentina of fatal septicemia caused by chromobacterium violaceum.a case of chromobacterium violaceum fatal septicemia is reported. the microorganism was isolated from six blood cultures and two suppurated skin lesions. it is the first such case described in argentina, and it reinforces the need for prolonged treatment and careful clinical evaluation to ensure complete remission of human infections caused by this bacterium.19863711283
nonfatal chromobacterial sepsis.we have described a case of multiple liver abscesses caused by chromobacterium violaceum. this organism should be considered in any case of unexplained liver abscess occurring in the southeastern united states. successful treatment of liver abscesses caused by this organism may be accomplished with appropriate antibiotic therapy.19863750002
isolation and characterization of aerobic heterotrophic bacteria from natural spring waters in the lanjaron area (spain).aerobic, heterotrophic bacteria were isolated from nine natural mineral water springs in the lanjaron area of spain over the period july 1980 to may 1981. the mineral waters contained few bacteria (mean counts 26-5275 cfu per 100 ml) and the bacterial flora of all nine springs was very similar. most of the isolates were gram-negative rods (90%), and among these pseudomonas spp. and members of the flavobacterium-cytophaga-flexibacter group were numerically dominant. aeromonas-vibrio and enterobac ...19863781942
[fatal septicemia due to chromobacterium violaceum].a 2-year old boy was suffered from an infection caused by chromobacterium violaceum. this is the first case of c. violaceum infection reported in taiwan. the boy was treated with chloramphenicol and gentamicin but died after one month of illness due to the incooperation of patient's family. the causative agent was isolated from patient's blood and scar. complete bacteriologic characteristics and antimicrobial susceptibility pattern of this isolate are reported.19863816371
novel potentiators of beta-lactam antibiotics. isolation of sq28,504 and sq28,546 from chromobacterium violaceum.two novel compounds, sq28,504 and sq28,546 are produced by chromobacterium violaceum. these compounds enhance the antibacterial activity of beta-lactam antibiotics against gram-negative organisms. both sq28,504 and sq28,546 induce morphological changes in the presence of beta-lactam antibiotics. only sq28,546 has weak antimicrobial activity against several gram-negative organisms.19853839229
