The growth of soil fungi Penicillium in the presence of N-(2-pyridylamino)methylenebisphosphonate as an alternative source of nutrients

2017

Kwas N-(2-pirydyloamino)metylenobisfosfonowy wykazują dużą aktywność herbicydową. W związku z tym należy zbadać jego odziaływanie na mikroorganizmy glebowe. Celem przeprowadzonych badań była ocena zdolności glebowych szczepów Penicillium do wzrostu w obecności kwasu N-(2-pirydyloamino)metylenobisfosfonowego jako alternatywnego źródła fosforu lub azotu lub węgla. Hodowle grzybów prowadzono w pełnym i zmodyfikowanym mineralnym podłożu Czapek, w temperaturze 25°C, przez 1–4 tygodnie. Modyfikacja podłoża polegała na wprowadzeniu 1 mM kwasu N-(2 pirydyloamino)metylenobisfosfonowego jako alternatywnego źródła składników odżywczych. Kontrolę względną stanowił wzrost grzybów w pełnym mineralnym pod…

Herbicidal activity of phosphonic, phosphinic, and phosphonous acid analogues of phenylglycine and phenylalanine

1995

A series of phosphonic, phosphinic, and phosphonous acid analogues of phenylglycine and phenylalanine was synthesized and tested as herbicides against Lepidium sativum and Cucumis sativus. Aminobenzylphosphonic acids exhibited notable herbicidal activity and thus represent a group of the most active herbicides found among aminophosphonic acids.

Determination of glyphosate and its metabolite aminomethylphosphonic acid in fruit juices using supported-liquid membrane preconcentration method wit…

2005

Abstract The application of supported-liquid membrane (SLM) technique for effective extraction of N -(phosphonomethyl)glycine (glyphosate) and its primary metabolite aminomethylphosphonic acid (AMPA) from juices (orange, grapefruit, apple and blackcurrant) in combination with HPLC-UV detection after derivatization with p -toluenesulphonyl chloride (TsCl) is presented. The influence of various parameters such as the composition of acceptor phase, flow-rate, concentration of analytes, on the performance of extraction procedure, was studied. It was shown that by appropriate manipulation of SLM parameters the level of detection could be significantly improved. The influence of SLM conditions on…
