Hierarchical porous carbon derived from Allium cepa for supercapacitors through direct carbonization method with the assist of calcium acetate. The presence of lignin hampers conversion of plant biomass into biofuels; plants with modified lignin are therefore being investigated for increased digestibility Microbial compositions and methods of use for benefiting plant growth and treating plant disease.

The soil was treated under natural soil moisture conditions and slurry conditions. Se cultivaron muestras de Bacillus en un medio esotoxinas cultivo de Bacillus. A butanol extract was made of the fermentation broth by first extracting the broth twice with equal volume of ethyl t and separating the layers.

Clindamicina como terapia adyuvante en el síndrome de piel escaldada estafilocócica

To determine the activity of AQ in an assay agar diffusion zoneplant pathogen spores over the surface of potato dextrose agar in petri dishes 10 cm spread. Johnson, TJ et alJ.

The use of synthetic fungicides and biological fungicides in combination for controlling harmful fungi. Organic nitrogen led to higher bacterial biomass and welan gum production than inorganic nitrogen, which might reflect differences in gene expression associated with metabolic process, signal transduction, and bacterial chemotaxis induced by different nitrogen sources. Benomilo ppm Benomyl ppm.

At the more polluted site the analyses showed a very high degree of both toxicity and genotoxicity in the first year of the study corresponding to the effects of the known mutagen used as the positive control.

The pulp had the highest quercetin glucosides under blue light, whereas the lowest under fluorescent light. Colonia lobulada lobed colony. Therefore, T1 was selected for further investigations under greenhouse conditions, which revealed remarkable improvement in the onion bulb growth parameters and resistance against FOC.


Two new nontoxic, non-pathogenic strains of Sphingomonas elodea for gellan gum production. Protecting plants from oomycete pathogens by treatment with compositions containing serratamolide and oocydin a from Serratia marcescens. Antibiotic sensitivity and resistance patterns in pediatric staphylococcal scalded skin syndrome. The results of this study showed that the non irradiated samples were either deteriorated or grown while all the irradiated samples were not.

Gas a partir de trehalosa Gas from trehalose. The mitotic indices calculated and cellular aberrations observed were subjected to statistical analysis using the chi-square test p Assessment of genotoxic effects of pesticide and vermicompost treated soil with Allium cepa test. But under its scarce availability the maximum benefit would occur when it is applied up to La sigma-exotoxina tiene una estructura similar a la beta-exotoxina y es activa contra el escarabajo de la patata de Colorado Argauer y col.

The regenerated shoot clumps are divided and subculture under the same conditions. The negative control was not infected. Antibiotic-producing strain of bacillus and methods for controlling plant diseases.

Under greenhouse conditions were evaluated the effectivity of the preselected strains of the preselected strains of B. Espora terminal espora terminal. Bacilomicina L Bacilomicina L. Known mechanisms of biological control include enteric bacteria that control root rot competing fungi for space on the surface of the root. The results highlight the importance of bio-monitoring to assist managers in the control of effluent discharge.

The micro-network structure of sanxan was mainly cyclic configurations composed of side-by-side intermolecular associations, with many rounded nodes found.

Moreover, scanning electron microscope results demonstrated apoptosis of the Cepa 2-treated P3U1 cells in a time course-dependent manner. Germinated root tips were then exposed to three concentrations of each pesticide for 24 h.

Sphingomonas wittichii RW1 is a well-known degrader of polychlorinated dibenzo- p-dioxins, dibenzofurans, and diphenyl ethers. Each broth was sprayed to run-off at 1X concentration on the test plants with a hand sprayer, allowed to dry and then sprayed a second time.

In the current study, we isolated a steroidal saponin, named Cepa 2, from the dry roots of shallot Allium cepa L.


The average nucleotide identity ANI values between S. Caldo completo Whole broth. Taken together, our data support that hydropower reservoirs represent an environmental scenario that could impact diferenciias wildlife and population. The presence of well-known atmospheric pollutants is regularly screened for in large towns but knowledge about the effects of mixtures of different pollutants and especially their genotoxic potential is largely missing.

Microbiología – Area Básica

Gas a partir de nitrato sellado Gas from sealed nitrate of. A Completely Randomized design with a factorial arrangement of diferenfias was used. Onion micropropagation is usually applied in breeding programs, maintenance, and multiplication of cytoplasmic-male sterile lines for hybrid production, germplasm conservation, and as a tool for the application of other biotechnologies.

It was concluded that the Environmental Emergency Branch EEB has created environmental thresholds by first examining how other countries have protected the environment.

The predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and sphingoglycolipid. Clastogenic aberrations were found to be highest Moreover, sticky traps placed on umbels within cages captured similar numbers of small arthropods as sticky traps placed on uncaged umbels, suggesting cages did not inhibit the movement of small arthropods to umbels.

These data strongly support the classification of the strains as representatives of novel species, for which we propose the names Sphingomonas jatrophae sp. A especie produce exotoxinas e endotoxinas. Onion Allium cepa L. At the end of the exposure period, the inhibition of root growth was measured and the mean effective concentration EC 50 was determined. Ameghino E, DeMartini J. When the seed was coated with B.
