Ovocidal activity of microbial agent for composting in vitro experiment against Toxocara cati eggs

Abstract

The purpose of the research is to study ovocidal properties of a microbial agent for composting that has lactobacilli (Lactobacillus casei and L. plantarum) and microscopic fungi (Saccharomyces cerevisiae) present as active components for Toxocara cati eggs in vitro experiment.Materials and methods. The tested microbial agent is used for compost preparation and liquid household waste processing. The agent is a homogeneous yellow liquid with a bacterial biomass in titers of 106 -108 CFU/cm3 which is placed in a ten-liter canister. First, a culture of Toxocara cati eggs was prepared, then ovocidal properties of aqueous standard solutions of the test agent were studied in four concentrations, 1.0%; 5.0; 10.0 and 50.0% versus a 4.0% phenol solution in vitro experiment.Results and discussion. The ovocidal effect of the tested aqueous microbiological agent solutions in the above concentrations in vitro experiment on T. cati eggs was not detected. A 4.0% phenol solution used as a reference solution showed high efficacy.
