The study aims to evaluate enzymes that facilitate fungal degradation of paraeforce. Soil samples for fungal isolation were collected from impacted sites and inoculated on potato dextrose agar (PDA). The isolates were screened for growth and tolerance to paraefoce in 50 mg/l concentration of the test herbicides. Trichoderma, Aspergillus and Rhizopus species were found to grow in paraeforce supplemented PDA. Qualitative and quantitative assay for different enzyme production in hydrogen peroxide, methyl red, guaiacol and hydrogen peroxide-pyrogallol complex proved potential for catalase, lignin peroxidase, laccase and manganese peroxidase production, respectively. The results showed that these three fungi have great potential for catalase, peroxidase and laccase production after six days aerobic incubation in paraeforce and these enzymes facilitated the utilization of the paraeforce.
Despite the importance of psychological wellbeing of survivors to the attainment of the envisaged goal of the downsizing practice, research on this group of workers is still limited particularly in Nigeria. The study aims at exploring the psychological impact of downsizing on survivor managers in Nigeria using a qualitative research approach. More specifically, unstructured and semi-structured interviews were carried out at different stages with a total of 20 interviewees. Data were analysed and coded using a data-driven thematic analysis. The finding revealed that anxiety, a feeling of uncertainty, insecurity of job, reduction in individual motivation and poor communication influenced the survivors negatively. These negative psychological and emotional impact exhibited by the survivor employees are linked to lack of jobs, high rate of unemployment, and lack of social security and culture. The outcome of the study would provide implications for human resources managers in Nigeria who often deal with downsizing and engaged in psychological contract breach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
