Resumen:
At the present time, one of the environmental challenges is the microbiological control in the indoor environment. Themicroorganisms that form biofilms on substrates located inside buildings and houses contribute to the formation of bio-aerosolswhen they are, partial or totally, dispersed and transported by the air. An example is the poisoning by certain fungal products asthe mycotoxins (carcinogenic) that comes from fungi that can generally be in the interiors of buildings. Therefore, it is of vitalimportance to contribute avoiding and/or minimizing the microbiological growth in the indoor environments. In such sense theevaluation of new antimicrobial agents is of fundamental importance and can be applied in diverse areas of development ofprotective coating and construction materials. The global efforts to reduce the dangerous remainders and technologically cleanthe chemical processes are being integrated with modern progresses as much in science as in the industry. In this investigation wewill work with remainders of seeds of sunflower functionalized with 3-aminopropyltriethoxysilane (APS), as support ofadditives, to a compound of Mo and K, that will act as antimicrobial, to be used in hygienic paintings. The originating solid of thesunflower seeds will be functionalized by means of reactions between organosilanes and the superficial groups of the mentionedsolid. The characterization of synthesized solids will be made by means of SEM-EDS, DRX, FT-IR, textural properties,potentiometric titration, among others. These solids were microbiologically evaluated in front of fungi and bacteria, givingpromissory results for novel ecological additives in hygienic paints.
