effect of biotin on fatty acids and phospholipids of biotin-sensitive strains of rhizobium japonicum.the effect of biotin on fatty acids and intact lipids was studied by comparing a biotin-requiring, a biotin-inhibited, and a biotin-indifferent strain of rhizobium japonicum. these organisms were grown in a defined medium with added levels of 0, 0.3, and 0.5 mug of biotin per liter, and were analyzed for fatty acids and lipid components. myristic, palmitic, and octadecenoic acids were found to be the major fatty acids in these strains. the indifferent strain also contained large amounts of c(19) ...19705437727
active transport of glucose-1-phosphate in agrobacterium tumefaciens.the presence of an active transport system for glucose-1-phosphate in agrobacterium tumefaciens was demonstrated from the following observations. (i) the bacterium could grow on a medium containing glucose-1-phosphate as carbon source; (ii) the entry of glucose-1-phosphate into the resting cells occurred against concentration gradient obeying michaelis-menten kinetics; and (iii) the entry reaction was energy-dependent. the transport system for glucose-1-phosphate was formed inducibly by growing ...19705438042
alpha-3-ketoglucosidase of agrobacterium tumefaciens.a 3-ketosucrose-degrading enzyme was purified 80-fold from the sonic extracts of agrobacterium tumefaciens iam 1525 grown on a sucrose-containing medium. the enzyme catalyzes hydrolysis of alpha-3-ketoglucosides such as 3-ketosucrose, 3-ketotrehalose, 3-ketomaltose, and 3-ketoglucose-1-phosphate but not of beta-3-ketoglucosides, beta-3-ketogalactosides, and other glycosides such as sucrose, trehalose, maltose, glucose-1-phosphate, cellobiose, lactose, or raffinose. from the strict substrate spec ...19705438043
gluconate catabolism in rhizobium japonicum.gluconate catabolism in rhizobium japonicum atcc 10324 was investigated by the radiorespirometric method and by assaying for key enzymes of the major energy-yielding pathways. specifically labeled gluconate gave the following results for growing cells, with values expressed as per cent (14)co(2) evolution: c-1 = 93%, c-2 = 57%, c-3 = 30%, c-4 = 70%, c-6 = 39%. the preferential release of (14)co(2) from c-1 and c-4 indicate that gluconate is degraded primarily by the entner-doudoroff pathway but ...19705438044

purification and some properties of a non-haem iron protein from the bacteroids of soya-bean (glycine max merr) nodules.a non-haem iron protein was isolated from an extract of soya-bean nodule bacteroids by a procedure including protamine sulphate and heat precipitation followed by chromatography on deae-cellulose. the purified protein contains non-haem iron and acid-labile sulphur and exhibits a spectrum with a rather broad absorption shoulder in the region 380-440nm and a more prominent peak at 280nm. from sedimentation-velocity measurements an apparent s(20,w) value of 1.3s was calculated. the protein function ...19705529239

effect of manganese and zinc ions on the growth of rhizobium.five strains, representing four species of rhizobium, were grown in specially purified synthetic culture solutions with manganese or zinc ion concentrations ranging from 0 to 10(-5)m. omission of mn(2+) restricted growth to 0.4 to 10% of that of controls, depending on the species. growth was generally maximum with 10(-6)m mn(2+) and nearly so with 10(-5)m. omission of zn(2+) restricted growth to 1 to 20% of that of controls. growth was generally maximum with 10(-7)m zn(2+). the 10(-5)m level of ...19704914077

d-glucaric acid and galactaric acid catabolism by agrobacterium tumefaciens.cell-free extract (crude extract) of agrobacterium tumefaciens grown on d-glucuronate or d-glucarate converts d-glucarate and galactarate to a mixture of 2-keto-3-deoxy- and 4-deoxy-5-keto-d-glucarate. these compounds are then converted by partially purified crude extract to an intermediate tentatively identified as 2,5-diketoadipate. the same enzyme preparation further decarboxylates this intermediate to alpha-ketoglutarate semialdehyde, which is subsequently oxidized in a nicotinamide adenine ...19704314480

multiplication of certain soil micro-organisms under simulated martian conditions.according to earlier observations, severe uv irradiation kills all micro-organisms in a chamber with simulated martian conditions. however, even a thin soil layer protects buried micro-organisms from uv irradiation. the chief limiting factor for microbial multiplication under simulated martian conditions seems to be soil humidity. several micro-organisms were isolated from harsh environments (e.g., from arctic, antarctic desert and high-mountain soil samples). a strain of an oligonitrophilic myc ...197012664919
interrelationships between root-nodule bacteria, plant-parasitic nematodes and their leguminous host.the effect of infection by meloidogyne javanica and heterodera trifolii on number, size, structure and efficiency of nodules formed by rhizobiurn trifolii on white clover roots was investigated. introduction of nematodes one week before, simultaneously, or one week following inoculation with rhizobium bacteria did not hinder nodule formation. nodule size did not differ between nematode-infected and nematode-free plants. formation of nodules on m. javanica galls and gall formation on the nodules ...196919325677
α-aminoadipic acid and α,ɛ-diaminopimelic acid in inoculated pea plants (pisum sativum) and root nodule bacteria (rhizobium leguminosarum).observations were made on the content of α-aminoadipic acid and α-aminophimelic acid (dap) in pea plants, nodules and rhizobium leguminosarum, strain ht3. the preparations were purified by ion exchange chromatography, qualitative analyses were made by paper chromatography, and quantitative analyses by means of an automatic amino acid analysator. in the whole plant and seeds the content of α-aminoadipic acid soluble in 70% ethanol varied between 10 and 80 μg/g dry weight. the shoot and red nitrog ...196920925682
immunochemistry of newly found substituents of polysaccharides of rhizobium species.acetyl and pyruvic acid groups were detected and estimated in the extracellular polysaccharides of rhizobium trifolii and r. meliloti. pyruvic acid was found also in the specific polysaccharide of pneumococcal type 27, and is believed to explain the cross-reactivity between antiserum to pneumococcal type 27 and these and other pyruvate-containing bacterial polysaccharides. removal of pyruvate from a rhizobium polysaccharide rendered it inactive with its homologous antiserum and with antiserum to ...19694388781

conversion of glucose-1-phosphate to 3-keto-glucose-1-phosphate by cells of agrobacterium tumefaciens.incubation of resting cells of agrobacterium tumefaciens with glucose-1-phosphate resulted in the accumulation of a new sugar phosphate in the suspending medium. approximately 80% of the glucose-1-phosphate consumed was converted to the new compound, which was identified as alpha-d-ribo-hexopyranosyl-3-ulose-1-phosphate (3-ketoglucose-1-phosphate). both utilization of glucose-1-phosphate and accumulation of 3-ketoglucose-1-phosphate were inhibited by 2,4-dinitrophenol, polymyxin, and d-glucose, ...19694304223

the relationship between nitrogen fixation and the production of hd from d2 by cell-free extracts of soya-bean nodule bacteroids.1. cell-free extracts prepared from soya-bean nodule bacteroids produced hd from d(2) in the presence of dithionite, an atp-generating system and nitrogen. 2. crude extracts of bacteroids or of azotobacter vinelandii showed some background d(2) exchange when any one of these was omitted. 3. partial purification of bacteroid extracts diminished this background activity and gave increased d(2) exchange and nitrogen fixation. 4. although increasing pn(2) stimulated both reactions, the apparent k(m) ...19695353527
