Yerba mate is consumed mainly in the Rio de la Plata basin areas, including Paraguay, south Brazil, Uruguay and Argentina, and it is exported to several countries where it is not cultivated, mostly to Lebanon and Syria and in lesser quantities to Israel, Kuwait, China, Chile, the United States and several european countries ( Alonso & Desmarchelier 2005 ALONSO J & DESMARCHELIER C. Effects of water quality on dissolution of yerba mate extract powders. 2014 HUANG WY, LEE PC, HSU JC, LIN YR, CHEN HJ & LIN YS. Shotgun sequencing for microsatellite identification in Ilex paraguariensis (Aquifoliaceae). 2013 PEREIRA MF, CIAMPI AY, INGLIS PW, SOUZA VA & AZEVEDO VC. Potential uses are under study and new products are being developed ( Pereira et al. Some examples are powdered yerba mate and mate flavoured baked goods and sodas, as well as toiletries with yerba mate as their main component. New yerba mate products have been introduced to the market in the last decades. The leaves are consumed as an infusion macerated with either hot (“mate”) or cold water (“tereré”). It requires warm (between 15 and 25☌) and moist weather (about 1300 to 2200 mm of annual precipitation per year) for optimal growth ( Margalot 1994 MARGALOT JA. This species occurs naturally on lateritic soils (“tierra colorada”) as a part of the understory layer of some forests ( Alonso & Desmarchelier 2005 ALONSO J & DESMARCHELIER C.

Its leaves are green and perennial, with slightly serrated margins ( Margalot 1994 MARGALOT JA. It becomes a tall tree when it grows in the wild, but it is shorter when cultivated. Hil.) is a plant species of south American origin. In conclusion, further studies to determine the ability of these isolates to adapt to the climatic conditions and to survive amidst the native soil microflora in yerba mate cultivated native soils, will be crucial for developing such strains as biofertilizer.īacillus altitudinis Bacillus circulans biofertilizer Ilex paraguariensis PGPR yerba mate After 120 days plants showed higher root dry weight when inoculated with isolate 19RS3 and higher shoot dry weight with 19RS3 and T5S-T4. Yerba mate seedlings were inoculated with the most promising isolates, which were identified via analyses of the sequence of their 16S rDNA gene as Bacillus circulans (12RS3) and Bacillus altitudinis (19RS3, T5S-T4). Isolates were selected based on their sporulation capacity and evaluated for in vitro plant growth promoting properties (nitrogen fixation, phosphate solubilization, production of siderophores and synthesis of indolic compounds). The objective of this study was to isolate spore-forming endophytic bacteria with plant growth promoting properties associated with yerba mate seedlings and determine their phytobeneficial effect under controlled laboratory conditions. Despite being an important crop for the region, there are few studies on the use of microorganisms to improve the growth of seedlings in the nursery stage. Hil.) is a species native to the subtropical regions of South America.
