Article Synopsis
  • European countries have recognized mealworm powder as a safe alternative protein source for humans, driven by population growth, but face marketability challenges due to safety concerns.
  • The study investigated microbial safety and aflatoxin levels in two batches of mealworm larval powder produced in Zimbabwe, analyzing for fungi, bacteria, and toxins.
  • Results showed that harmful microorganisms and aflatoxin levels were below food safety thresholds, suggesting that mealworm powder is safe for human consumption.

The challenge in polystyrene disposal has caused researchers to look for urgent innovative and ecofriendly solutions for plastic degradation. Some insects have been reported to use polystyrene as their sole carbon source, and this has been linked to the presence of microbes in their guts that aid in plastic digestion. Thus, this study focuses on the molecular detection and phylogenetic analysis of the alkane-1-monooxygenase (alkB) gene in strains isolated from the gut of .

larvae are the first insect species to be given a favorable assessment by the European Food Safety Authority (EFSA) as a novel food source, enabling consumption of whole insect larvae or larvae that have been powdered and processed into a variety of food products. Pressure from economic hardships and increase in population growth have paved a way for the realization of an alternative food source in Zimbabwe. This study focused on determining the potential toxicity of larvae powder as an alternative food source for humans.

Mushrooms are known to possess a diversity of bioactive compounds that include lectins, which are proteins or glycoproteins that bind specifically to cell surface carbohydrates, culminating in cell agglutination. The present study describes the screening of lectin activity from ten local mushrooms, namely, Amanita zambiana, Boletus edulis, Cantharellus heinemannianus, Cantharellus miomboensis, Cantharellus symoensii, Lactarius kabansus, Amanita sp., Coprinus sp.

Background: The excessive use of polystyrene as a packaging material has resulted in a rise in environmental pollution. Polystyrene waste has continually increased water pollution, soil pollution and the closing of landfill sites since it is durable and resistant to biodegradation. Therefore, the challenge in polystyrene disposal has caused researchers to look for urgent innovative and eco-friendly solutions for plastic degradation.

Conservation decisions based on neutral genetic diversity have been observed to promote retention of useful quantitative variation in biological populations. An experiment was undertaken to determine the association between microsatellite marker polymorphisms and phenotypic variation in semen production and cryosurvival traits in bulls. Thirty-five ejaculates were collected from ten bulls of two breeds and evaluated before and after cryopreservation for several semen traits.

Article Synopsis
  • The study investigated the differences in sperm cryosurvival between two breeds of Sanga cattle (Mashona and Tuli) and how using ethylene glycol (EG) instead of glycerol (GLY) might affect it.
  • Tuli bulls had larger but lower quality ejaculates compared to Mashona bulls, with Mashona semen showing better motility and morphology.
  • Results indicated that using EG instead of GLY did not improve sperm quality or cryosurvival significantly between breeds, implying that other mechanisms may influence sperm cryostress tolerance.
