Microbes as climate engineers

29.01.2008
We might think we control the climate but unless we harness the powers of our microbial co-habitants on this planet we might be fighting a losing battle, according to an article in the February 2008 issue of Microbiology Today.

Humans are continually altering the atmosphere. “Arrogant organisms that we are, it is easy to view this as something entirely novel in Earth’s history,” says Dr Dave Reay from the University of Edinburgh. “In truth of course, micro-organisms have been at it for billions of years.”

Humans affect the atmosphere indirectly by their activities. Most human-induced methane comes from livestock, rice fields and landfill: in all of these places, microbes are actually responsible for producing the methane, 150 million tonnes a year. Microbes in wetlands produce an additional 100 million tonnes and those that live inside termites release 20 million tonnes of methane annually.

90 billion tonnes of carbon a year is absorbed from the atmosphere by the oceans, and almost as much is released; microbes play a key role in both. On land, a combination of primary production, respiration and microbial decomposition leads to the uptake of 120 billion tonnes of carbon every year and the release of 119 billion tonnes.

“The impact of these microbially-controlled cycles on future climate warming is potentially huge,” says Dr Reay. By better understanding these processes we could take more carbon out of the atmosphere using microbes on land and in the sea. Methane-eating bacteria can be used to catch methane that is released from landfill, Cyanobacteria could provide hydrogen fuel, and plankton have already become a feedstock for some biofuels.

“Microbes will continue as climate engineers long after humans have burned that final barrel of oil. Whether they help us to avoid dangerous climate change in the 21st century or push us even faster towards it depends on just how well we understand them.”

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
