Penicillium mould, light micrograph
Penicillium mould. Light micrograph of a section through an orange rind infected with Penicillium sp. blue mould fungus, showing fungal hyphae and conidiophores (pink and purple) with spores (red). This saprophytic mould produces spores that germinate and pierce the rind of the orange. They then produce hyphae (tubular, purple), which infect the cells of the orange and suck out nutrients. The hyphae then pierce the rind with stalked conidiophores that produce rows of conidiospores on the outer surface of the rind, which are dispersed by the wind. Penicillium is used to produce penicillin, an antibiotic. Magnification: x70 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate world of Penicillium mould. The image reveals a section through an orange rind infected with the blue mould fungus, offering a glimpse into its parasitic nature. The pink and purple conidiophores stand out against the backdrop, adorned with vibrant red spores that are ready to be dispersed by the wind. The saprophytic mould's life cycle is unveiled in this snapshot. It begins with spores germinating and penetrating the orange rind, followed by the production of tubular hyphae that invade and extract nutrients from the fruit's cells. As if piercing through armor, stalked conidiophores emerge from these hyphae to release rows of conidiospores on the outer surface of the rind. Penicillium not only captivates us visually but also holds great significance in medicine as it is used to produce penicillin—an essential antibiotic. This light micrograph magnifies this microscopic wonder seventy times when printed at ten centimeters wide, allowing us to appreciate its beauty while delving into its biological intricacies. Through this stunning visual representation, we gain insight into how diseases can manifest even within seemingly healthy fruits like oranges. It serves as a reminder of nature's complexity and highlights our ongoing fascination with uncovering hidden wonders at a microscopic level.
