Energy flow through living systems is the focus of the biochemistry subfield known as bioenergetics. Transferring and converting energy is a topic of active biological research. It has uses in structural biology, mitochondrial metabolism, and diseases of that metabolism. The goal of the peer-reviewed, open-access Bioenergetics Journal is to publish the most thorough and trustworthy source of information on new findings and advancements in all fields of study through the publication of original articles, review articles, case studies, short communications, etc. and to make this information freely accessible online to researchers all over the world without any restrictions or additional subscriptions.

The study of the makeup and biology of microbial communities in the environment is known as environmental microbiology. Microorganisms are typically out of sight and out of mind, but they are a huge, incredibly diverse group of organisms that are ubiquitous and the primary form of life on Earth. Microorganisms are found on almost every surface, including our skin, although most are safe for people to be around. Some microbes can survive in hot springs that are scalding, while others grow as microbial colonies in sea ice that has frozen over. Microorganisms have a variety of roles, including those in soil fertility, biogeochemical cycling, the decomposition of dead plants and animals, and the biodegradation of several complex organic compounds found in the environment.

The study of microorganisms in the soil, water, and air, as well as their use in bioremediation to lessen environmental pollution through the biological breakdown of pollutants into non-toxic or less hazardous chemicals, are the focus of environmental microbiology. Environmental microbiology also deals with issues including microbial induced bio corrosion, biological deterioration of building materials, and the microbial composition of both indoor and outdoor air. Temperature, the need for oxygen, pH, and the availability of water are environmental elements that affect microbial development.

Depending on the organism, the ideal temperature, pH, and moisture levels can differ. Some of them may develop in brine at 20 °C to prevent freezing, while others can develop in a high-pressure environment at 120 °C to prevent boiling. Psychrophiles are microorganisms that thrive at temperatures below 20 °C, mesophiles are those that thrive between 20 °C and 50 °C, and thermophiles thrive at temperatures over 50 °C. Hyper thermophiles, who often belong to the Archaea, have an ideal growth temperature between 70 °C and 110 °C. Obligatory aerobes are cells that need oxygen for metabolism and growth; obligate anaerobes cannot proliferate in the presence of oxygen, whereas facultative anaerobes can grow with or without oxygen. Microaerophiles don't care about oxygen, although aero tolerant anaerobes (obligate fermenters) do. Each bacterial species has a pH range where it may survive, but this range also contains its pH optimum. Acidophiles and alkalophiles both grow best at pH values below 5.5 and above 8.5, respectively. Neutrophiles proliferate in the pH range of 5 to 8. Finally, water is necessary for the flourishing of all microbes any microorganism's ability to grow depends not only on a favourable physical environment but also on the availability
