This study was conducted to investigate microbial community changes during the field-scale composting of the anaerobic digested pig manure sludge. Samples were obtained from an influent tank (Inf.) and anaerobic digestion tank (A. d.) of pig manure slurry, and the early stage of compost depot (Com. 1 and Com. 2). Input of the compost process was produced by the solid-liquid separation process o...

In this study, a South African mine tailing sample was characterized for base metals using X-Ray fluorescence, alkaline fusion, and acid digestion to subsequently evaluate the uncertainties involved. This based on importance of characterization data in subsequent methods obtaining confidence such methods. It determined that instrument repeatability reproducibility contributed most overall uncer...

Abstract Goat yogurt samples fortified with 20% (w/v) Rhus coriaria leaf powder were in vitro digested order to evaluate the total phenolic content (TPC), antioxidant activity (AA), and bioaccessibility of compounds digestate. After digestion, TPC AA values R. coriaria-fortified yogurts increased compared undigested (P < 0.001). In particular, has about twice; whereas, have 10 6 times, for ABTS...

To characterize aspartyl aminopeptidase from Aspergillus oryzae, the recombinant enzyme was expressed in Escherichia coli. The enzyme cleaves N-terminal acidic amino acids. About 30% activity was retained in 20% NaCl. Digestion of defatted soybean by the enzyme resulted in an increase in the glutamic acid content, suggesting that the enzyme is potentially responsible for the release of glutamic...

The present experiment was carried out to determine the digestion kinetics of carbohydrate fractions of citrus by-products. Grapefruit pulp (GP), lemon pulp (LE), lime pulp (LI) and orange pulp (OP) were the test feed. Digestion kinetic of whole citrus by-products and neutral detergent fiber (NDF) fraction and acid detergent fiber (ADF) fractions of citrus by-products were measured using the <e...

background: sediments in marine environment have a large capacity in binding with heavy metals; therefore, they are potential pollutants of water resources. the anzali wetland, located in the southern region of the caspian sea, iran, has been consistently threatened by heavy metal pollutants because of urban, agricultural and industrial wastewater inflow. the purpose of this study is to investi...

We describe a simplified, automated method for screening urinary iodine. Digestion with strong acid is avoided by dialyzing urine and then directly analyzing iodine in the dialysate with the ceric ion-arsenious acid system. This method is particularly useful for analyzing large numbers of samples without loss in precision. Urinary iodine excretions are reported for 1224 children 1 to 6 years of...

A serendipitously discovered oxidative esterification reaction of cyclohexane hexacarboxylic acid with phosphorus pentachloride and phenols provides one-pot access to previously unknown aryl mellitic acid esters. The reaction features a solvent-free digestion and chromatography-free purifications and demonstrates the possibility of cyclohexane-to-benzene conversions under relatively mild, metal...

Suspensions of Blepharisma intermedium were fed latex particles for 5 min and then were separated from the particles by filtration. Samples were fixed at intervals after separation and incubated to demonstrate acid phosphatase activity. They were subsequently embedded and sectioned for electron microscopy. During formation of the food vacuole, the vacuolar membrane is acid phosphatase-negative....
