Microbial food spoilage refers to the degradation of food quality resulting from the metabolic activity of microorganisms such as bacteria, yeasts, and molds. These microbes proliferate on various food substrates depending on factors such as moisture content, nutrient availability, and storage conditions, leading to undesirable sensory and structural changes.Bacteria are primary agents of spoilage in high-moisture, nutrient-dense foods like meat, milk, and vegetables. Microbial spoilage occurs...

The cultivation of environmental microorganisms has long been hindered by the inability to replicate complex native conditions in vitro. The isolation chip (iChip) addresses this limitation by facilitating the growth of previously uncultivable microorganisms through in situ incubation. Designed for high-throughput microbial cultivation, the iChip comprises hundreds of microchambers, each capable of housing a single microbial cell. These microchambers are loaded with a mixture of molten agar and...
