When we think of semiarid we always associate with the lack of water, food, agriculture and livestock that end up generating little
local development and, in consequence, poverty. However, little is exploring local biodiversity and adapted to that situation.
In Brazil, we have a vast area of territory with hot semi-arid climate and only from mid-2010 began to be exploited as the local
biodiversity. Microbiological part is even more incipient. In 2014, a previous analysis of microbiome at different times of the year
showed a significant difference of 16S rDNA size amplified in the same environment. This year we will start a microbiome work to
understand what happens in these environments in different periods of drought. In 2016, lipolytic bacteria from hot springs were
isolated. Lipases showed greater activity above 158oF and pH between 10 and 12. Later this year, we began an isolation of phosphate
solubilizing, nitrogen fixers and auxin producing bacteria. By the time we succeeded in isolating more than 100 strains, among
them was a symbiotic of Adenium obesum (desert rose) that is being considered for use as an agricultural inoculant. Furthermore,
we developed a mead production method that reduced the months of fermentation timeout to 15 days which enables the industrial
production of this beverage and will be the first start-up of the region. These findings suggest that semiarid is really rich in microbial
