A huge number of date varieties grow annually throughout the world. The genetic variation between different is reflected in their variable sensory characters and phytochemical contents. Date pits are considered a waste product industry, despite rich metabolic content. present study attempts to generate visual clustering clarify diversity among fourteen cultivars growing Qassim region, according...

This article provides an overview of the role raw and burnt date pits as bio-waste for heavy metal removal. In recent years, many studies on adsorption properties various low-cost adsorbents, such agricultural waste activated carbons based waste, have been published. review summarizes research demonstrating utility modified biomass-based adsorbents in removal pollutants from wastewater. Additio...

How Mining Releases Toxic Metals Large amounts of waste rock and tailings contaminated with toxic metals can be produced by mine sites. In the case of the Donlin Creek mine, there are only 0.072 ounces of gold for every ton of ore, a figure that does not take into account the waste rock. Toxic substances contained within the rock and tailings are more easily released once these substances are p...

Total DNA was isolated from swine feces and a swine waste storage pit and used as templates for PCR amplification of archaeal 16 rDNA using specific primers. Only the sample from the center of the waste pit produced a PCR product. DNA sequence analyses of random clones demonstrated a variety of methanogenic archaea. Six groups of sequences were identified, including those similar to Methanobrev...

organic fraction of solid waste, which upon degradation produces foul smell and generates pathogens, if not properly managed. composting is not a method of waste disposal but it is a method of waste recycling and used for agricultural purposes. an integrated approach of composting methodology was tested for municipal solid waste management. solid waste first was composted and after 22 days, was...

the objective of present study was to determine the effects of β-mannanase-based enzyme (hemicell®) on productive performance and egg quality in diets containing graded levels of whole date waste (wdw) fed to laying hens. a total of 336 hy-line leghorn hens after production peak were randomly divided into 56 cages. eight iso-energetic and iso-nitrogenous experimental diets in a 4 × 2 factorial ...

In this trial effects of feeding pistachio by-product silage with date waste (PBSD) on dry matter intake (DMI), live weight gain and blood parameters of lambs were studied. Ensiling of pistachio by-products (PBP) with date waste increased dry matter (DM) and metabolizable energy (ME), but decreased the percentages of crude protein (CP), total tannins and phenolic compounds (P
