Some years ago, microorganisms capable of mimicking the benefits of chemical fertilizers began to be studied and could function as the perfect complement for a more sustainable agriculture. Salinity 15% . The main stresses faced by desert organisms are thus infrequent and unpredictable access to water, high rates of water loss, extreme temperatures and large temperature ranges. Bacteria and other soil organisms benefit from the release of organic acids by fungus, an increase in oxygen from the activity of algae, a shift in soil response, etc. Another extreme environment is created by a rock known as serpentinite. Enhanced agricultural production is essential for increasing demand of the growing world population. These microbes are not only subject to water deprivation but also face a number of other environmental factors such as wide temperature ranges and nutrient starvation [2]. These can be found in deep ocean niches, at the peaks of high . Microbes are the most abundant organisms in the biosphere and regulate many critical elemental and biogeochemical phenomena.

[CAIRO] Desert soil microbes could help halt desertification and boost agriculture in arid regions of the Middle East and North Africa, according to a study. Together they form a unique fingerprint. Extreme environments are classified into the following groups based on the extreme physicochemical conditions: Extreme temperature: Two types of extreme environments can be described; cold and hot. Although super hardy in extreme climates, surviving near boiling temperatures or being frozen, they have an Achilles heel, a single weak spot. Source: Adapted from World Atlas of Desertification (Cherlet et al., 2018). By Mary Sabuda. W Alsharif, MM Saad, H Hirt. A wide array of microorganisms, including many novel, phylogenetically deeply rooted taxa, survive and thrive in extreme environments. In agricultural education and research, the study of agricultural microbiology has undergone tremendous changes in the past few decades, leading to today's scientific farming that is a backbone of economy all over the globe. Soil 22%. By the year 2050, we will be 9.5 billion. The use of beneficial bacteria, termed plant growth promoting bacteria (PGPB), as biofertilizers for improving plant growth is widely recognized [ 25 - 27 ]. Bacteria have a bad reputation, but many of them are beneficial to humans and ecosystems.
