Soil microorganisms, such as bacteria and fungi, are important biotic factor for the conservation of soil fertility, promotion of plant development and establishment of healthy ecological relation in ecosystems. The download region of Central Mexico, known as Baj?o, is an important region placed in the confluence of Nearctic and Subtropical biogeographic regions.The growth of population, agriculture and industrialization seriously impact plants, animal and environmental conservation. We started a global ecological study of those areas, including bioprospection of microbial biodiversity. Hundreds of bacterial and fungi isolates were collected and characterized. Many of them exhibited biological activities for biotechnological purposes. Herein we showed isolated spore forming Gram positive bacteria active against whiteflies (Bemisia tabaciG.,Hemiptera:Aleyrodidae) mediated by 100 kDa S-Layer protein, a protein belonged to slp2 gene group.

Keywords : Bacillus thuringiensis, S-layer protein, Bemisia tabaci.
