ABSTRACT

INTRODUCTION: Anti-Black racism is a social determinant of health that has significantly impacted Black children and families. Limited research has examined anti-Black racism during the early years-a critical period of development. In this study, we sought to understand the manifestations of anti-Black racism in early childhood and explore its impact on Black children and families. METHODS: This qualitative research project was informed by critical race theory, Black Critical Theory and interpretive description. Early childhood educators (ECEs) and parents with Black children between the ages of 18 months and 5 years (n = 15) participated in virtual, semistructured interviews. RESULTS: Awareness of and protection against anti-Black racism was a constant in Black families' lives. Parents felt as though they had to remain hypervigilant and overprotective of their Black children, knowing they were liable to encounter racial violence. The early learning environment was a source of heightened stress for families, given the significant amount of time young children spend in child care. Black children were often "othered" in predominately White spaces and had been objectified by White ECE staff and children. Parents worked to instill a strong sense of self-confidence in their children to counteract the negative impacts of racial discrimination. CONCLUSION: Results from this study suggest that children as young as 18 months are experiencing racial violence and adverse childhood experiences. Findings may contribute to antiracist policy development and a focus on more inclusive early childhood education for Black children and families.

ABSTRACT

Fungi are excellent producers of extracellular enzymes. Therefore, the present study aimed to investigate the screening of marine fungi, which are laccase and manganese peroxidase potential producers, in solid fermentation for future applications in bioremediation processes of contaminated sites. For this purpose, two-level factorial planning was adopted, using time (6 and 15 days) and the absence or presence of oil (0 and 1%) as factors. The semi-quantitative evaluation was carried out by calculating radial growth, enzyme activity and enzyme index by measuring phenol red or syringaldazine oxidation halo. The results showed that all the studied strains showed a positive result for manganese peroxidase production, with an enzymatic activity in solid medium less than 0.61, indicating a strongly positive activity. Through the enzyme index, the study also showed prominence for Penicillium sp. strains, with values > 2. The enzyme index increase in oil presence and the inexpressive use of the genera studied for ligninolytic enzymes production from crude oil demonstrated these data importance for fermentative processes optimization. Considering the ability of these strains to develop into recalcitrant compounds and the potential for manganese peroxidase production, they are indicated for exploitation in various bioremediation technologies, as well as other biotechnological applications.
