The geomicrobiology of iron, cobalt, nickel and manganese in lateritic tropical soils from the Santa Elena Peninsula, Costa Rica
(2019)
There is an increasing interest in the biogeochemistry of metals, like cobalt, fuelled by the growing need for batteries and other high technology products. Bioprocessing of Co has been proposed to improve its recovery ...
Antimicrobial activity of different sodium and potassium salts of carboxylic acid against some common foodborne pathogens and spoilage-associated bacteria
Actividad antimicrobiana de diferentes sales de ácidos carboxílicos de sodio y potasio contra algunos microorganismos patógenos y de deterioro asociados a alimentos
(2018)
Cleaning and disinfection represent the most important activities associated with the elimination of dirt and microorganisms at food processing plants. Improper procedures may lead to cross contamination of food leading ...

Synthesis, structure and spectroscopic characterization of Ni(II), Co(II), Cu(II) and Zn(II) complexes with saccharinate and pyrazole
(2007-09)
Four mononuclear mixed-ligand complexes of Co(II), Ni(II), Cu(II) and Zn(II), with saccharin (sac) and pyrazole (Hpz) were synthesized and characterized on the basis of elemental analysis, FT-IR spectroscopy, magnetic ...
Derivados del fenantreno [9,10-d] Imidazol
(1981)
A simplified synthetic method of the phenanthro[9,10-d]imidazol (1) is reported in this work. The acetyl derivative (2) and a new cupric complex (3) of the imidazole (1) are synthesized, and the structures assigned on the ...
Light Reflection by Cuticles of Chrysina Jewel Scarabs: Optical Measurements, Morphology Characterization, and Theoretical Modeling
(2016)
Cuticles of some Chrysina scarabs are characterized by flat, graded, and twisted structures of nanosized chitin fibrils. As inferred from SEM images, each species has its own spatial period or pitch P which is dependent ...
Expanding the Trichoderma harzianum species complex: Three new species from Argentine natural and cultivated ecosystems
(2021-06-22)
A study was performed on a collection of 84 isolates from decaying plant tissues and soils in
Argentina previously identified as Trichoderma harzianum. Based on multiple phenotypic characters
and multilocus phylogenetic ...
Differential volatile organic compound expression in the interaction of Daldinia eschscholtzii and Mycena citricolor
(2023)
Fungi exhibit a wide range of ecological guilds, but those that live within the inner
tissues of plants (a.k.a. endophytes) are particularly relevant due to the benefits they
sometimes provide to their hosts, such as ...
Reactivity and structure of derivatives of 2-hydroxy-1,4-naphthoquinone (lawsone)
(2007-11)
The structures of two derivatives of 2-hydroxy-1,4-naphthoquinone (lawsone) are examined using the density functional theory (DFT) hybrid functional B3LYP. Using the optimized structure of lawsone acetate, the reactivity ...
