The research is potentially attractive for converting
silica rich biomass into useful materials. Silica containing
specimens prepared by the thermalmethod and deposition from
rice production waste (straw and husk) were evaluated for their
ability to remove different strains of microorganisms from the
water. The strains of microorganisms with different cell shape
and size were chosen for investigation:
Escherichia coli
,
Bacillus subtilis
,
Candida albicans
,
Pseudomonas aeruginosa
,
Staphylococcus aureus
and freshwater heterotrophic bacterial
association. The results obtained have been discussed as compared
to the physical and chemical parameters of the sorbents:
their composition, specific surface value, pore size, zeta
potential value and surface hydrophobicity. Our study showed
that removal efficiency of SiO
2 specimens and alumosilicate
sample prepared from rice husk to different strains of microorganisms
was higher that of other specimens including commercial
sorbent. The use of various processing schemes for rice
production waste let to obtain efficient selective sorbents
