Autoclave Pasteurization

Autoclave pasteurization is a heat-based decontamination approach that uses pressurized steam to reduce or eliminate microorganisms in biological materials, making it important for safe laboratory work. In an autoclave, saturated steam transfers heat efficiently, and elevated pressure allows temperatures commonly around 121°C to penetrate liquids, culture media, and contaminated waste; exposure time depends on the load and volume. Although this process generally achieves sterilization rather than conventional pasteurization, the term may describe autoclave treatment used to make materials biologically safer. In biology, it supports media preparation, waste management, and contamination control, while careful loading and validation help ensure effective treatment.

2023

Robert M. Rioux & Zhifeng Chen, Pennsylvania State University, University Park, PA Autoclaving is one of the most commonly used methods in the laboratory for the purpose of decontamination. The most common items decontaminated with an autoclave are those that contact biological samples (typically those containing microorganisms). An autoclave works by utilizing pressurized high temperature steam to kill microorganisms present in the loaded materials. Sufficient steam flow and heat transfer...

Pasteurization is a widely employed thermal processing technique designed to enhance the safety and shelf life of perishable food and beverages. By subjecting products to specific high temperatures for controlled durations, this method effectively inactivates pathogenic microorganisms and spoilage enzymes without significantly compromising sensory qualities. The technique has been pivotal in food safety management, especially for consumables susceptible to microbial contamination such as milk,...

While infiltrating macrophages are continuously recruited to adult tissues from circulating precursors, resident macrophages seed their tissue during development, where they are maintained without further input from progenitors. The progenitors for resident macrophages were recently identified. Here, we present methods for the genetic fate mapping of the resident macrophage progenitors.

Mouse ultrasonic vocalizations are used as proxies to model the genetic bases of vocal communication deficits in mouse models for neuropsychiatric disorders. The present protocol describes three experimental contexts that reliably elicit ultrasonic vocalizations from pups (throughout development) and adult mice (same-sex interactions, male-estrus female interactions).
