Abstract:
In this paper the authors presented the influence of various urea phosphate doses, 1-12%, on the environmental fungi growth depending on its intensity and the type of created spore e.g. (Penicillium italicum, Aspergillusfumigatus, Aspergillus niger, Cladosporium resinae, Mucor hiemalis i Rhizopus nigricans). The result of urea phosphate effect on fungi was estimated by static culture method using dry mass increase change [g. dry mass/ldm3]. The control was created by the growth of the above mentioned fungi on the basis of urea phosphate free soil. The obtained results were worked out by a statistic method using Duncan's test. The tested fungi showed different sensitivity to the various urea phosphate doses. In the presence of 1% urea phosphate the fungi sensitivity depended on their growth intensity (Aspergillus niger, Mucor hiemalis i Rhizopus nigricans). Additionally, the stimulation of fungi growth with rapid vegetative structure progress was observed. Independently of their physiological properties, significant inhibition of dry mass increase in the range of 3-12% concentration urea phosphate was observed. The result of the use of 3% urea phosphate was the reduction of dry mass growth of all tested fungi.
Insights
Urea phosphate impacts environmental fungi growth. While low doses (1%) can stimulate some fungi, higher concentrations (3-12%) significantly inhibit fungal dry mass, affecting various species like Aspergillus and Penicillium.
Area of Science:
- Environmental microbiology
- Agricultural science
Context:
- Fungal contamination poses challenges in various environments, including agriculture and industrial settings.
- Understanding the impact of soil amendments like urea phosphate on fungal communities is crucial for effective management.
Purpose:
- To investigate the dose-dependent effects of urea phosphate on the growth of common environmental fungi.
- To determine the sensitivity of different fungal species to urea phosphate concentrations.
Summary:
- The study examined urea phosphate's influence on Penicillium italicum, Aspergillus fumigatus, Aspergillus niger, Cladosporium resinae, Mucor hiemalis, and Rhizopus nigricans using static culture and dry mass measurements.
- A 1% urea phosphate dose showed varied effects, stimulating growth in some fungi (Aspergillus niger, Mucor hiemalis, Rhizopus nigricans) but inhibiting others.
- Concentrations of 3-12% urea phosphate significantly inhibited dry mass increase across all tested fungal species, with 3% reducing growth in all fungi.
Impact:
- Results indicate that urea phosphate can act as a fungicide at higher concentrations, offering potential for controlling unwanted fungal growth.
- The findings provide valuable data for agricultural and environmental management strategies involving urea phosphate application.
