“…Therefore, the conservation of biodiversity in agriculture is a challenge of great importance. Several studies have demonstrated the contribution of ecosystems such as rice, providing habitats for creation of numerous microorganisms (Hofman et al 2003;Maltick et al 2010). The microorganisms in the biosphere perform important functions, for example, the influence on biogeochemical processes.…”

This work presents bibliographic data on the role and function of microbial diversity. The increasing use of probiotics and prebiotics foods has led to the studies on their actual functions in the human body. It is known that in the environment, microorganisms are extremely important in recycling of nutrients, balance of trophic chains, vital physiological activities in the plants and animals, as well as the conservation of natural habitats. In human food, these microscopic organisms contribute from flavoring products to the synthesis of antimicrobial substances and vitamins essential to living beings.

“…Because of the relatively direct linkage between soils biological activity and many ecosystem-level processes (decomposition, nutrient mineralization), soils microorganisms provide a good opportunities for investigating ecosystem-level responses to disturbances and stress gradients [51]. Soil microbial biomass is the primary catalyst of biogeochemical processes as well as an energy and nutrient reservoir [44], [19], [20], [46], [55], [3], [22], [23], [31]. In low fertile soils with a high proportion of nutrients immobilized in the belowground living biomass, standard soil fertility tests are of little value.…”

Abstract. Soil microbial biomass is considered as an important early indicator of changes that may occur in the long term with regard to soil fertility and constitutes an important source and sink of nutrients. In South Africa, rangeland monitoring has mostly focused on assessing changes of aboveground vegetation in response to land uses effects, but the associated changes at belowground soil level remain a topic of further research. The aim of this study was to explore soil microbial biomass at three sites under communal grazing management. Soils from grazed and adjacent ungrazed rangeland plots were collected at a depth of 0-25 cm towards the end of the rainy season in April 2005. The soil microbial biomass was characterized by analyzing the phospholipids ester-linked fatty acids. Soils were also analyzed for organic carbon, pH, and total phosphorus. Results showed no statistically significant differences in organic carbon and soil microbial biomass between the grazed and ungrazed plots at any of the sites. Both organic carbon and soil microbial biomass were low, ranging from 0.06 to 0.11% and 489.28 pmol g -1 to 1823.04 pmol g -1 , respectively. Fourteen grass species were recorded during the vegetation surveys, and most occurred in low abundance. Plants supply organic materials as energy sources for microbial growth, so the low soil microbial biomass could be a reflection of the low vegetation abundance. This study provides essential baseline information regarding soil microbial activity never reported before in these rangelands. Further investigations are required for in-depth understanding of the underlying processes that regulate soil microbial biomass dynamics at these sites.
