Abstract

The aim of this study is to find bacterial strains with antagonistic effects against Fusarium oxysporum f. sp. lycopersici ( Fol) and Ascochyta sp, which are phytopathogens responsible for fusarium wilt of tomato and ascochyta blight of peas, respectively. One hundred thirty- six bacteria isolated from the rhizosphere of tomatoes were screened. Five strains with the largest inhibition zones were selected. These strains were identified by the phenotypic method, later confirmed by sequencing of 16S rDNA. All strains belonged to the genus Bacillus spp. Their inhibition capacity was evaluated by the direct method by doing a dual culture, the inhibition rates ranged from 44.32 ± 0.8 to 61.36 ± 0.2 against Fol and 62.04 ± 0.8 to 74.1 ± 0.2% against Ascochyta sp. They were then evaluated by the indirect method by evaluating, on one hand, the antifungal effect of the volatile compounds produced by the strains and on the other hand, the antifungal effect of the filtrates. The results showed that volatile compounds inhibited plant pathogens’ growth with average inhibition rates of 55% against Fol and 17% against Ascochyta. For filtrates, the average inhibition rates were 33.01% against Fol and 33.74% against Ascochyta sp. Finally, the plant growth promoting rhizobacteria (PGPR) effect of B. halotolerans RFP57 was evaluated. This involved assessing their ability to stimulate the germination of tomato seeds and the growth of their vegetative organs. The results showed significant improvement in treated seedlings compared to controls. All these results show that the strains selected for this study have the potential for use as a biocontrol agent. However, it is clear that further in-depth studies are needed to confirm their true potentiality.

Abstract

Although John Rawls’s theory is an extensive project of the state structure which also discusses the functions of various democratic institutions, the reader tends naturally to look for something more, namely his opinions about human nature and the psychological underpinnings that ultimately determine men’s and women’s responsibilities in a democratic community. The clues offered by A Theory of Justice are disappointingly scarce, as they tend to blur the distinction between the descriptive and the normative aspects of the problem. Rawls’s analysis of such categories as moral sensitivity, or human motives, or social obligations do not take into account the natural limitations that typically accompany the demands formulated by the just state. Or, to put the same complaint differently, Rawls’s opinions about human nature sound unduly optimistic, if compared, for instance, with Kant’s moral theory to which he makes frequent references.

Abstract

The new challenges for Polish theology in the beginning of the 21st c. in the context of possession and exorcism include a theological reflection on possession and exorcism in the Bible, in patristic texts as well as in medieval and modern theological literature. Another issue is an elaboration of a new theological anthropology, which should acknowledge the achievements of human sciences like psychology and psychiatry. The existence of the psychic sphere in the human being is to be distinguished while the human spiritual sphere is to be convincingly justified. More precise criteria will be needed in order to distinguish psychic problems from those of a spiritual nature, including possession.
