Abstract: The present disclosure provides a Brevundimonas strain as an endosymbiont of Verticillium dahliae, which is named Brevundimonas olei dahliae olei (B. olei) and deposited with the accession number of CCTCC NO: M 2020392. Morphological identification and diversity sequencing analysis confirm that the symbiont is B. olei. The effect of B. olei fermentation broth on growth and microsclerotia of Verticillium dahliae is explored through a co-cultivation experiment. Observations through electron microscope find that, with the increase of culture time and fermentation broth concentration, the Verticillium dahliae forms fewer conidia, its hyphae swell, rupture, and become abnormal in shape, and its microsclerotia gradually decrease and even disappear.

Abstract: A method for producing an organic fertilizer enabling an increased microbial diversity and abundance in soil, and use of the organic fertilizer are provided. The method comprises composting fresh S. alopecuroides plants together with sheep and/or goat manure through anaerobic fermentation. It is found through experiments that, by applying the organic fertilizer produced by the method to a soil in which melon plants are grown, both abundance of bacterial and fungal communities in the rhizosphere of the plants and contents of soluble solids and sugar in fruit of the plants are increased. By a combination of taxonomic composition of the microbial communities in the rhizosphere and RDA analysis, it is further found that abundance of multiple bacterial and fungal species conducive to growth and disease resistance of the plants, is substantially increased and positively correlated with the soluble solids and sugar contents in the fruit.

Abstract: A method for evaluating measured electromagnetic (EM) data relating to a subsurface region, comprising the steps of: (a) specifying alternative models of the region in terms of input parameters with uncertainty; (b) receiving the measured EM data and an estimated error; and (c) carrying out a Bayesian inversion on the measured data using each of the alternative models to attribute a probability to each model on the basis of the measured data and estimated error. The method allows physical measurements with error to be translated into fundamental parameters which can be used to assess business risk and uncertainty for making decisions, and also provides for parameters and models which can typically be directly estimated by a geoscientist on a coarse spatial grid to be used as an input, and validated using the measured data with error.

Abstract: A method for evaluating measured electromagnetic (EM) data relating to a subsurface region, comprising the steps of: (a) specifying at least one model of the region in terms of fundamental parameters with uncertainty, using a fundamental inversion grid; (b) receiving the measured EM data and an estimated error; (c) translating the fundamental parameters of the model to meta parameters of the region and to a computational grid suitable for forward modelling and comparison to the measured EM data, using relationships with uncertainty; and (d) carrying out a Bayesian inversion using the measured data and estimated error to produce an output comprising fundamental parameters of the region on the fundamental inversion grid with uncertainty.

Abstract: An aircraft equipped for airborne vector magnetic exploration surveys comprising three magnetometers orthogonally mounted to measure the components of the earth's vector magnetic field; two rotation sensors mounted to measure the angular orientation of the aircraft; and a recording system to record the measurements of the magnetometers, and rotation sensors. The measured angular orientation is used to orientate the measured components of the earth's vector magnetic field to derive true vector aero-magnetic (VAM) data from airborne surveys. Also disclosed is a method for processing magnetic data by removing the permanent, induced, and eddy-current magnetic effects of the aircraft from the magnetic data.

The measured angular orientation is used to orientate the measured components of the earth's vector magnetic field to derive true vector acro-magnetic (VAM) data from airborne surveys. Also disclosed is a method for processing magnetic data by removing the permanent, induced, and eddy-current magnetic effects of the aircraft from the magnetic data.
