WebSep 14, 2024 · On Earth, phosphine has been found in abundance in anaerobic (low in oxygen) ecosystems. It's found in swamps and sludges, where anaerobic microbes thrive. … WebSep 12, 2015 · Phosphine is a significant gaseous carrier in the P cycle. The matrix-bound phosphine in the paddy soils and its relationship to environmental variables and bacterial community composition were studied. Materials and methods The ambient levels of matrix-bound phosphine (MBP) from four distinct sites in South China were investigated. WebIt seems that the effect of phosphine on fungal growth, however, may vary between fungal species and the type of stored grain or seed. Phosphine was shown to inhibit the growth of A. flavus and/or A. parasiticus and aflatoxin production on peanuts in both laboratory and warehouse experiments (Castro et al., 1992, 1995, 1996). onvif device manager deutsch download
