Degradation of a peroxisome by micropexophagy. The transfer of cytosolic components into the lysosomal compartment by direct invagination of the lysosomal membrane without prior sequestration into an autophagosome. The engulfing membranes fuse, resulting in the lysosomal delivery of the cargo wrapped in a single membrane derived from the invaginated lysosomal membrane. In S. cerevisiae, the vacuole is the lysosomal compartment. The process by which cells digest parts of their own cytoplasm; allows for both recycling of macromolecular constituents under conditions of cellular stress and remodeling the intracellular structure for cell differentiation. A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a peroxisome. A peroxisome is a small, membrane-bounded organelle that uses dioxygen (O2) to oxidize organic molecules. The process by which peroxisomes are delivered to the vacuole and degraded in response to changing nutrient conditions. The infolding of a membrane, resulting in formation of a vesicle.
