Thermophilic lipases derived from Stutzerimonas stutzeri have garnered significant attention in recent years due to their robustness and efficiency in various industrial applications. This review delves into the research, development, and application of these enzymes, with a comparative analysis between Nigeria and the United States. In both nations, researchers have explored the enzymatic properties of thermophilic lipases from Stutzerimonas stutzeri, aiming to optimize their performance for diverse industrial processes. The research encompasses studies on enzyme purification, characterization, and genetic engineering to enhance catalytic activity and stability under extreme conditions. Additionally, efforts have been directed towards understanding the enzyme's structure-function relationship to tailor it for specific applications. In Nigeria, the focus on thermophilic lipases from Stutzerimonas stutzeri has been primarily driven by the need for sustainable biotechnological solutions in various industries, including food, pharmaceuticals, and biofuel production. The enzymes' thermostability makes them particularly suitable for high-temperature processes prevalent in Nigeria's tropical climate, offering potential for cost-effective and eco-friendly alternatives to conventional chemical catalysts. In contrast, the United States has witnessed extensive research and development in thermophilic lipases for industrial applications, with a strong emphasis on biocatalysis in the pharmaceutical, detergent, and biofuel sectors. The advanced infrastructure and investment in biotechnology have facilitated the commercialization of Stutzerimonas stutzeri lipases, leading to their integration into various industrial processes to improve efficiency and sustainability. Despite the similarities in research objectives, disparities exist in the technological advancements and industrial utilization of thermophilic lipases from Stutzerimonas stutzeri between Nigeria and the US. While Nigeria faces challenges related to limited resources and infrastructure, the US benefits from well-established research institutions and industrial networks, enabling accelerated innovation and commercialization. Bridging these gaps through international collaborations and knowledge exchange could facilitate the widespread adoption of thermophilic lipases for sustainable industrial development globally.

Solid waste disposal methods within indigenous communities present unique challenges and opportunities for sustainable development. However, the current knowledge on solid waste management focuses on formal waste collection systems, neglecting the practices and sustainability aspects of solid waste management in indigenous communities. Thus, it becomes imperative to undertake research studies that evaluate the sustainability of these practices as they play a pivotal role in ensuring sustainable development. The current study systematically evaluates the views and judgments associated with the sustainability aspects of indigenous waste management practices in the rural communities of South Africa using the Analytic Hierarchy Process (AHP) model. The data analysis was carried out using the AHP model. The findings of this study showed that the rural communities of Bushbuckridge Local Municipality prioritize the sustainability of the environment (weight: 0.590) over the economic (weight: 0.240) and social sustainability (weight: 0.165) based on the AHP evaluative framework. The validity of the priorities was tested through the computed degree of consistency (<10%) and an eigenvalue of 5.107. Furthermore, according to the assessment in the current study, the AHP evaluative framework dominantly prioritizes the sub-criteria of environmental sustainability (composting) at a responding rate of over 70% almost across all indigenous communities except for Acornhoek (30%), Casteel (25%), and Mambumbu (24%). Likewise, the sub-criterion of social sustainability, which is associated with communal cleaning labor, was found to be of extreme importance (60%), outperforming taboos (10%) that are anchored in cultural and spiritual beliefs. With a response rate > 50%, waste trading proved to be of economic efficacy. Using the AHP model to evaluate the sustainability aspects associated with indigenous solid waste management practices addresses a substantial gap in the comprehension of the role of indigenous knowledge towards sustainability in the discipline of solid waste management. However, it also offers a valuable sustainability perception that is associated with indigenous waste disposal methods that local governments and policymakers should include for consideration in integrated waste management plans. This can lead to the development of waste disposal programs that are well-coordinated and in accordance with indigenous sustainable waste management practices that advance the circular economy and promote environmental protection.

Indigenous knowledge systems related to solid waste management in economically marginalized communities have been largely overlooked in the scientific literature, even though the indigenous communities of developing nations struggling to manage solid waste rely on these practices. It is startling that indigenous solid waste management practices are scarcely documented in the scientific literature despite their position as potential alternative disposal methods. This gap persists amid limited municipal budgets, inadequate waste collection services, and poor infrastructure in economically marginalized indigenous rural communities in developing nations. Subsequently, in the discipline of solid waste management, this obstacle impedes the recognition and inclusion of indigenous waste management practices into integrated waste management plans. As a result, this causes a delay in their progress or elevation to the same level of credibility as mainstream scientific knowledge. In the process, this relegates the waste management practices of indigenous communities to the background. Against this background, the current study sought to investigate the indigenous solid waste management practices of rural communities in Bushbuckridge Local Municipality. As such, ten cases that captured the spatial cultural diversity of indigenous communities’ practices across Bushbuckridge Local Municipality (BLM) were selected for sampling. Data were collected using ethnographic research methods. Data analysis was carried out using the thematic analysis approach. Inductive logic was used in the interpretation of the current study results. The results of the current study indicate that indigenous communities of Bushbuckridge Local Municipality, in the absence of formal waste management services from the local authority, resort to an indigenous knowledge system to manage solid waste. Waste burning (100%), open-air dumping (100%), and backyard pits (90%) are some of the indigenous waste management practices espoused by the rural communities of BLM. The similarity in practices was corroborated by statistical inferences that revealed that between BLM communities, the amount of indigenous waste management practices is not significant (p > 0.05). However, there are concerns that despite the sustainability aspect associated with recycling (<25%) practices, these disposal methods are not common in the rural communities of BLM. This is a setback for an indigenous knowledge system that is supposed to advance environmental sustainability practices.
