Tree encroachment into savannas alters soil microbiological and chemical properties facilitating forest expansion
(2016-10-01)
Forests have been expanding over typical savanna sites for the past 3000 years in the Neotropics. Such invasion can produce a series of environmental modifications on typical savanna; however, it remains unclear how ...
Validation of microbiological assay for determination of cefuroxime in injectable preparations
(2012-08-22)
The validation of a microbiological assay, applying agar diffusion method for determination of the active of cefuroxime in power for injection, is described. Using a strain of Micrococcus luteus ATCC 9341 as the test ...

Heat Treatment: Effect on Microbiological Changes and Shelf Life
(2016-01-01)
Foods are complex ecosystems constituted by the environment and the microorganisms that live in it. The food environment consists of intrinsic factors such as pH, water activity, and nutritional components and extrinsic ...
Microbiological Assay for the Determination of Colistin Sulphate
(Bentham Science Publ Ltd, 2014-01-01)
An innovative microbiological assay was developed for the determination of colistin sulphate at various concentrations (192-469 IU/mL); using Bordetella bronchiseptica ATCC 4617 as microorganism test. This assay revealed ...

Characterization of the fungitoxic activity on Botrytis cinerea of the aristolochic acids I and II
(WILEY, 2019)
The fungitoxic effect of aristolochic acids I and II on mycelial growth and conidial germination of Botrytis cinerea was analysed. Aristolochic acid I had a higher effect on mycelial growth of B. cinerea than aristolochic ...
BarR, an Lrp-type transcription factor in sulfolobus acidocaldarius, regulates an aminotransferase gene in a β-alanine responsive manner.
(Facultad de Ciencias, 2014)
In archaea, nothing is known about the β-alanine degradation pathway or its regulation. In this work, we identify and characterize BarR, a novel Lrp-like transcription factor and the first one that has a non-proteinogenic ...
