We determined if supplemental macronutrients or activated charcoal influenced intake of sagebrush, a shrub that contains terpenes. Sheep (lambs 3 mo age, 33 kg) and goats (kids 5 mo age, 28 kg) were fed supplements high in energy, high in protein, or offered a choice between the two supplements before and after receiving sagebrush for 4 h/d. The effect of activated charcoal, a compound that red...

Biochar applications to soils can improve soil fertility by increasing the soil's cation exchange capacity (CEC) and nutrient retention. Because biochar amendment may occur with the applications of organic fertilizers, we tested to which extent composting with farmyard manure increases CEC and nutrient content of charcoal and gasification coke. Both types of biochar absorbed leachate generated ...

in order to evaluate the effectiveness of the iranian made charcoal tubes in the field , 60 local made and 60 imported ones (skc type) were randomly selected and placed side by side for sampling aromatic hydrocarbons (including benzene, toluene, xylene) in workers breathing zone in a paint factory. the results indicated that there were no statistically significant differences between the mean c...

Charcoal-yeast extract agar is a new bacteriological medium that supports excellent growth of the Legionella pneumophila. It results from modifications made in an existing L. pneumophila medium, F-G agar. Yeast extract, instead of an acid hydrolysate of casein, serves as the protein source. Beef extractives and starch are not added. Activated charcoal (Norit A or Norit SG) is included at 0.20% ...

House dust mites produce potent allergens that exacerbate asthma in sensitized patients, whom are recommended to practice allergen avoidance within their home environment. We tested the effect of activated charcoal impregnated fibers on house dust mite survival. One hundred live adult house dust mites (Dermatophagoides pteronyssinus) were added to eight culture dishes preequilibrated at room te...

In our earlier investigation, a fungal isolate Penicillium citrinum VFI-51 and its secondary metabolite was reported to have antagonistic potential against Botrytis cinerea, the causative agent of Botrytis gray mold disease in chickpea. In the present investigation, P. citrinum VFI-51 was further evaluated for its antagonistic potential against Macrophomina phaseolina, the causative agent of ch...

The extraction of steroids from urine with the usual organic solvents is accompanied by the extraction of undesirable pigments which complicate the isolation of urinary steroids by paper chromatography. Even after preliminary fractionations by paper chromatographic techniques, Burton et al. (1) found that the residues were highly pigmented and bulky. This made the task of detecting minute amoun...

For centuries, activated Charcoal (AC) has been used externally in a poultice form to adsorb “poisons” trapped in the outer layers of skin and internally to relieve intestinal discomfort and to remove toxic materials. The largest use for activated charcoal, in our society, is as a filter bed in air and water remediation cartridges. Recently, scientists have formulated AC into a nonstick dermal ...

Siříšťová L., Přinosilová Š., Riddellová K., Hajšlová J., Melzoch K. (2012): Changes in quality parameters of vodka filtered through activated charcoal. Czech J. Food Sci., 30: 474–482. The production technology of high-quality vodka used in Russia involves filtration through activated charcoal. To approach the quality of renowned Russian vodka, one prominent Czech spirit-producing company inst...

The experimental materials comprised 800 Cobb 500 broiler chickens. One-day-old chickens of both sexes were randomly allocated to two feeding groups, each with four replicates of 100 birds. The chickens were reared for six weeks on deep litter and were fed standard pelleted diets in a three-stage system (starter, grower and finisher). Control group (I) birds received basal diets and experimenta...
