The electrochemical oxidation of formic acid was studied by the tip generation-substrate collection (TG-SC) mode of scanning electrochemical microscopy (SECM), extending the number of applications of SECM in electrocatalysis. Formic acid was generated at a Hg on Au ultramicroelectrode (UME) tip by reduction of CO(2) in a 0.1 M KHCO(3) solution saturated with this gas. The electrocatalytic activ...

Ag nanoparticles (NPs) were synthesized in formic acid aqueous solutions through chemical reduction. Formic acid was used for a reducing agent of Ag precursor and solvent of gelatin. Silver acetate, silver tetrafluoroborate, silver nitrate, and silver phosphate were used as Ag precursors. Ag+ ions were reduced into Ag NPs by formic acid. The formation of Ag NPs was characterized by a UV-Vis spe...

Formic acid, acting as both carbon and energy source, is a safe alternative to a carbon dioxide, hydrogen and dioxygen mix for studying the conversion of carbon through the Calvin-Benson-Bassham (CBB) cycle into value-added chemical compounds by non-photosynthetic microorganisms. In this work, organoautotrophic growth of Ralstonia eutropha on formic acid was studied using an approach combining ...

Formic acid is a representative carboxylic acid that inhibits bacterial cell growth, and thus it is generally considered to constitute an obstacle to the reuse of renewable biomass. In this study, Saccharomyces cerevisiae was used to elucidate changes in protein levels in response to formic acid. Fifty-seven differentially expressed proteins in response to formic acid toxicity in S. cerevisiae ...

We report a highly efficient water splitting for CO2 reduction into formic acid with a commercially available metal of Fe powder without adding any other catalyst. An excellent formic acid yield of more than 90% was attained.

The industrial solvent trichloroethylene (TCE) has been reported to increase the excretion of formic acid in the urine of male Fischer 344 (F-344) rats following large oral doses. We have examined the dose-response relationship for formic aciduria in male and female Fischer 344 rats, the effect of some known metabolites of TCE and examined the response in male Wistar rats to help understand its...

Four essential oils in two concentrations (50 and 100%) of thyme, Thymus vulgaris; Cinnamon, Cinnamomum zeylanicum; Lemon grass, Cymbopagon flexuosus; Anise, Pimpinella anisum and formic acid (65%) were used against varroa mite, Varroa destructor infesting honey bee colonies. Results show that, formic acid and the highest concentration (100%) of tested essential oils caused effective control of...

Four essential oils of Thyme (Thymus linearis), Lemon grass (Cymbopogon citratus), Rosemary (Rosmarinus officinalis), Mint (Mentha longifolia) and Formic Acid (65%) used at three concentrations (25, 50 and 100%) against Varroa destructor damaging honey bee Apis mellifera colonies in Honeybee Research Institute, National Agricultural Research Centre, Islamabad, Pakistan. The percentage of infest...

MALDI-TOF MS-based yeast identification requires a pretreatment step for which four are described in the literature, i.e., direct smear, fast formic acid and two complete formic acid/acetonitrile extractions. In this study we compared the impact of these procedures on the performance of MALDI-TOF MS-based yeast identification of samples from colonies grown on Sabouraud or chromogenic media. A t...

Original Article The objective of the present study was to evaluate the anticoccidial effects of formic acid in contrast to HCl in broiler chickens challenged with Eimeria tenella infection in comparison with the amprolium anticoccidial. For this purpose, a total of 225 chicks were placed 15 per pen with three pens per treatment. HCl (2000ppm), formic acid (5000ppm) and amproilum (at the dose r...
