Effects of soil treatments on the survival of soil microorganisms.
In biological control studies of plant-parasitic nematodes in field soil improved methods are needed for reducing or eliminating specific soil inhabiting microorganisms. Microwave heating of soil decreases soilborne fungi and bacteria, but not Pasteuria spp. Bacterial and fungal colony forming units were reduced to nondetectable levels in microwaved heated field soft (650 watts) at 5.2% moistur...
متن کاملSiderophore cooperation of the bacterium Pseudomonas fluorescens in soil
While social interactions play an important role for the evolution of bacterial siderophore production in vitro, the extent to which siderophore production is a social trait in natural populations is less clear. Here, we demonstrate that siderophores act as public goods in a natural physical environment of Pseudomonas fluorescens: soil-based compost. We show that monocultures of siderophore pro...
متن کاملPseudomonas fluorescens
nas incognita have been previously described as being able to utilize citronellol, geraniol, and linalool (3, 6). Recently, a 50-megadalton (MDa) plasmid has been associated with the degradation of geraniol (9). In this report we describe the isolation of a Pseudomonas fluorescens s train capable of utilizing linalool as a sole carbon and energy source and demonstrate the presence of a transmis...
متن کاملSome characteristics of proteolytic enzymes from Pseudomonas fluorescens.
Our interest was stimulated by observing the active proteolytic abilities of a culture of Pseudomonas fluorescens isolated from a frozen chicken pie. The culture liquified gelatin rapidly and attacked casein strongly. In addition, the culture displayed considerable lipolytic and amylolytic activity. The culture was isolated from a tryptone-glucose-meat-extract-agar plate after incubation at 5 C...
متن کاملSurvival of rifampin-resistant mutants of Pseudomonas fluorescens and Pseudomonas putida in soil systems.
The fate of spontaneous chromosomal rifampin-resistant (Rifr) mutants of Pseudomonas putida and Pseudomonas fluorescens in sterile and live organic soil from which they were isolated was studied. In sterile native-soil assays, a Rifr mutant of P. putida showed no decrease in competitive fitness when compared with the wild-type parent. However, mutants of P. fluorescens were of two general categ...
