Abstract: The present invention relates to a waste water treatment process and system for treatment of waste water utilizing a diatomite treatment agent containing about 98 to 99.9% by weight of diatomite particles, wherein the diatomite particles comprise unbalanced surface charges and is substantially free of counter ions being electrostatically coupled to the unbalanced surface charges, and wherein the diatomite treatment agent is obtained from the disclosed pre-treatment process. This diatomite treatment agent has posed several advantages in a waste water treatment process, particularly acting as a biomass carrier, physical coagulant and adsorbent in a system for treatment of waste water, the system comprising a specially designed clarifier.

Abstract: The present invention belongs to the field of molecular biology. Specially, the invention relates to the screenings of a new drug target, a vaccine antigen and a test target of anti-tuberculosis treatment. Specially, based on the differential proteome technology and by the techniques of gene sequencing, in vitro protein expression, immunological detection and gene recombination, the invention primarily certifies that the up-regulated expression of Protein Rv2629 and the mutation of Gene 191A/C of Mycobacterium tuberculosis are related to the Rifampicin (RFP) drug-resistance, which provides useful information for the drug-resistance detection of Mycobacterium tuberculosis, the novel drug design and the vaccine development. Firstly, the drug-resistant strains are cultured and the proteins from drug resistance strains and sensitive strains are isolated respectively.
