This study investigates the effects of sieved wastes generated from the brewing industry on lightweight aggregates manufactured with clay. Sludge from a wastewater treatment plant, bagasse and diatomaceous earth were used to obtain the samples. These wastes are usually dumped in landfills, but the current increase in restrictions on dumping and interest in improving the environment make our pro...

Three soft fungicides were evaluated for the control of Botrytis cinerea on kiwifruit in laboratory and field experiments. Four isolates of B. cinerea were tested against two standard fungicides (carbendazim and sulphur) and three products: Mycosin (Schaette) and Mycosan (Schaette), commercially available BIOGRO certified fungicides based on diatomaceous earth, and chitosan (Sigma), derived fro...

The effects of positively charged nylon and depth (cellulose-diatomaceous earth) filters on endotoxin removal from various solutions were evaluated. The charged filter media removed significant amounts of Escherichia coli and natural endotoxin from tap water, distilled water, sugars, and NaCl solutions; no significant removal of endotoxin was observed with negatively charged filter media. The e...

Gastrointestinal parasites (worms) in sheep and goats are common in all world regions. Parasite burdens have undermined survival of producers and are a limiting factor for farm profitability. Additionally, rampant worm resistance to commercially available anthelmintics adds complexity to parasite management plans and researchers have been looking for alternative compounds with effective anthelm...

A method for ethyl carbamate (EC) determination in alcoholic beverages and soy sauce was developed by GC-MS. We adopted the diatomaceous earth solid-phase extraction (SPE) column and elution solvent of ethyl acetate/diethyl ether (5:95 v/v) for sample cleaning. The in-house validation showed the limit of quantification (LOQ) was 5.0 μg/kg. In the accuracy assay, the total average recovery for w...
