Eco-toxicological effects of pesticide residues on soil biological sentinels

Journal of Applied Sciences and Environmental Management, 2018
This research studied the eco-toxicological effects of pesticide residues on soil biological sentinels. Nitrobacter and Nitrosomonas sp. was isolated from Soil samples gotten from dumpsite in Benin City and cultured using Winogradsky medium.

Isolation of Nitrosomonas from Rothamsted Soil [PDF]

Nature, 1949
SINCE Nitrosomonas, a bacterium which oxidizes ammonia to nitrite, was discovered by Warington1 and the Franklands2 and first isolated by Winogradsky3, nearly sixty years ago, there are only a few records of its isolation in pure culture.

Ammonia oxidizing archaea and bacteria respond to different manure application rates during organic vegetable cultivation in Northwest China

Scientific Reports, 2023
Ammonia oxidization is a critical process in nitrogen cycling that involves ammonia oxidizing archaea (AOA) and bacteria (AOB). However, the effects of different manure amounts on ammonia-oxidizing microorganisms (AOMs) over the course of organic ...

Innovative Field Applications of Probiotics, Prebiotics, and Medicinal Plant Products for Disease Control in Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Disease outbreaks and the associated reliance on antibiotics pose major constraints to the sustainability of modern aquaculture. As regulatory pressures increase and consumer demand shifts toward residue‐free production, diverse biological interventions are gaining prominence as viable alternatives to chemotherapeutics.

Evaluation of polyurethane sponge biocarrier effects on Litopenaeus vannamei cultivation in zero water exchange systems based on water quality, shrimp performance and bacterial community analysis

Frontiers in Environmental Science, 2023
To evaluate the effects of polyurethane sponge biocarriers with precultured biofilms (PSBF) on water quality, shrimp performance and bacterial communities, zero water exchange systems for Litopenaeus vannamei were constructed. The experiment consisted of
