AI Article Synopsis

  • The study investigated how different concentrations of diluted bovine manure (1.0% and 0.1%) influence the attachment and detachment of Cryptosporidium parvum oocysts to soil, compared to no manure.
  • The findings revealed that manure increased the attachment of oocysts to soil, with the highest attachment seen at 0.1% concentration.
  • Additionally, the study found that while oocyst attachment is mostly reversible, maximum detachment occurred with diluted manure, highlighting the complex effects of manure on oocyst movement in soil.

Article Abstract

The objective of this work was to assess the effect of dilute bovine manure (1.0% and 0.1%) versus that of no manure on attachment and subsequent detachment of Cryptosporidium parvum oocysts to soil. Manure enhanced the attachment of oocysts to soil particles; the maximum attachment was observed with 0.1% manure. Oocyst attachment was partially reversible; maximum detachment was observed with dilute manure. These results indicate that oocyst attachment to soil is substantially affected by bovine manure in a complex manner and should have implications for how oocysts may be transported through or over soils.

The Silway River has historically failed to meet safe fecal coliform levels due to improper waste disposal. The river mouth is located in General Santos City, the tuna capital of the Philippines and a leading producer of hogs, cattle, and poultry. The buildup of contaminants due to direct discharge of waste from chicken farms and existing water quality conditions has led to higher fecal matter in the Silway River.

High salinity, low fertility and poor structure in saline-alkali soils led to nutrient cycling slow and microbial activity loss. The application of amendments has proven effective in enhancing soil nutrients, which significantly affects soil nitrogen and phosphorus cycling process. However, the specific impact of different amendments on the microbial functional potential related to nutrient cycling in saline-alkali soils remains unclear.

Biochar supplementation affects the microbiome of recycled manure solids for cow bedding: a metagenomic analysis.

The widespread use of Recycled Manure Solids (RMS) as cow bedding material is not without risks, since cattle manure may act as a vehicle for pathogenic and antimicrobial resistant bacteria dissemination. Thus, our aim was to evaluate RMS-supplemented with a pine biochar produced in Portugal as a new cow bedding material, since the use of biochar has been shown to have the potential to mitigate the impact of relevant bacterial species when added to animal manure microbiota. Our experimental setup consisted on fresh RMS samples that were collected on a commercial dairy farm and placed in naturally-ventilated containers for a total of 4 groups: 1-non-supplemented RMS; 2-RMS supplemented with 2.

Biochar has been used to accelerate heating profiles during composting by increasing oxygenation, which could also reduce microbial pathogens. However, the antimicrobial inactivation of foodborne pathogens in compost, by amending with biochar without increased heating profiles, has not been evaluated. In this study, we examined the ability of biochar to inactivate E.

Carbon-nanotube-modified biochar (CNT3-CBC) with a nanostructured surface was prepared by using cattle manure as the raw material via the impregnation method. This modified biochar was then used to adsorb petroleum and Ni(II) from aqueous solutions. Various physicochemical characterization techniques were employed, including SEM, BET analysis, FTIR, and XPS.
