Universities in Africa are increasingly expected to demonstrate contributions to the Sustainable Development Goals (SDGs), and microbiology occupies a distinctive position within this expectation because microbial processes underpin infectious disease control, food safety, soil fertility, water quality, waste treatment and bio-based production. Claims that higher education institutions can convert microbiological research into development impact are frequent, yet the evidence linking institutional activity to measurable outcomes has not been critically synthesised for the African context. This critical narrative review examines how African universities generate, mediate and constrain SDG-relevant impact through microbiology research, training and innovation, and evaluates the strength of the evidence behind prevailing claims. Peer-reviewed and authoritative institutional literature published between January 2015 and July 2026 was identified through international multidisciplinary, biomedical and education indexes, regional African sources and citation tracking, and was appraised thematically. The synthesis indicates that the most robust evidence of impact concerns public-health microbiology, where university-anchored genomic surveillance, laboratory quality improvement and antimicrobial resistance data generation have informed outbreak response. Evidence for agricultural and environmental applications is more heterogeneous. Biological control of aflatoxin shows large and replicated reductions in contamination, whereas rhizobial and other microbial inoculants show variable field responses alongside weak regulatory and quality-assurance systems. Across domains, impact depends less on scientific capability alone than on sustained funding, equitable partnership governance, laboratory infrastructure, regulatory pathways and the absorptive capacity of health systems, firms and communities. Persistent authorship asymmetries, short grant cycles, procurement delays, workforce attrition and incomplete integration of data into policy limit the durability of gains. Measurement is a further weakness, because ranking systems and bibliometric mapping of SDG relevance produce inconsistent results and rarely capture outcomes. The review proposes a conditional framework that separates established from hypothesised pathways and identifies priorities for longitudinal, comparative and outcome-oriented evaluation. The available evidence supports a qualified conclusion: African universities can act as effective SDG partners through microbiology, but mainly where institutional, financial and governance conditions allow research capacity to be retained, trusted and translated.
