World climate change has triggered soil water stress and imposed limitations on agricultural production. Plant growth-promoting bacteria (PGPBs) have been an efficient strategy to improve the biological supply and growth of plants under distinct abiotic stress conditions. We hypothesized that the soils from a temporary pond may harbor PGPBs with potential strains which increase maize tolerance to water deficit. We studied rhizosphere and bulk soil of Mimosa bimucronata in a temporary pond from semiarid Northeast Brazil to access strains with characteristics to promote plant growth and mitigate abiotic stress for maize crop. We isolated 355 bacterial isolates, from which 96 were selected based on the morphophysiological characterization to assess IAA production (42 % produced over 50 ug mL-1 of IAA), calcium phosphate solubilization (with one isolate achieving medium IS), biofilm and exopolysaccharides production (66 % and 98 % of isolates, respectively). Based on these mechanisms, the 30 most promising bacterial isolates were selected to assess biological nitrogen fixation (74 % of the isolates showed nitrogenase activity greater than 20 C2H4.h-1.mg-1), ACC deaminase activity (80 % of isolates) and growth in medium with reduced water activity (8 % of isolates grew in medium with water activity (Aw) of 0.844). We sequenced the 16S rRNA gene from the seven most promising isolates in in vitro and in vivo assays, which were identified as Staphylococcus edaphicus, Bacillus wiedmannii, Micrococcus yunnanensis, Streptomyces alboflavus, Streptomyces alboflavus, Bacillus wiedmanni and Bacillus cereus. In vivo, eleven isolates and three bacterial consortia did not differ from the control with nutrient solution, for total leaf area and root dry mass of maize. S. alboflavus (BS43) had the best in vivo results, not differing from the control with nutrient solution. We highlight the unpublished potential of Staphylococcus edaphicus and Streptomyces alboflavus in promoting the growth of plants under water stress. In addition, it is the first report of bacteria isolated from a temporary pond in the Brazilian semiarid which promoting plant growth attributes and development.

With the capacity to produce different enzymes, macrofungi are able to efficiently degrade a wide rage of substances, so that, they are used as biodetoxification and bioremediation agents. For the ability to adapt in most variable and extreme conditions, different biomasses can be used as substrate for growth of macrofungi and obtention of by-products with great interest for industry. In this chapter, it will be further explored the efficiency and importance of wild mushroom as bioconversion and biotransformation agents of vegetal biomass, and the importance of these fungi as decomposers agent in the soil and finally explore the tools (omics) to understand the mechanism of the process. Macrofungi are vital agents for the maintenance of life on earth, meanly because of their capacity to biodegrade organic matter, such as all the components of wood. Purified enzymes from a macrofungus can be used for the production of new, valuable by-products from a specific substrate in a process called biotransformation. The fungi need to obtain energy from a nutrient source to create a new product. Complex substrates generally need to be degraded to produce sugars. This process is called biodegradation, which is applied to the disintegration of any matter by biological means. Biodegradation occurs through the action of specialized enzymes; some of these enzymes, called promiscuous enzymes, are able to degrade several analogous substrates. Through the action of these enzymes, the fungi are able to degrade/remove some toxic/xenobiotic substances by a process called biodetoxification. When the elimination of the xenobiotic compounds occurs in contaminated media, including water, soil and subsurface material, the fungus/microorganism performs a bioremediation or mycobioremediation. When the macrofungi are able to degrade complex organic matter into mineral samples, this process is called mineralization.
