Abstract: The present invention discloses a method for advanced treatment of bio-treated coking wastewater. It employs polymeric ferric sulfate (PFS) and polyacrylamide (PAM) as the flocculant for the pre-treatment of bio-treated effluent. After the process of precipitation and filtration, the effluent is guided through an adsorption column filled with environmentally-friendly nano-composites whereby the advanced treatment of the bio-treated coking wastewater is achieved. When the absorption process reaches the breakthrough point, the adsorption operation will be stopped and sodium hydroxide solution is used as the desorption reagent for regenerating the nano-composites. The high-concentrated component of the desorption liquid is sent out for incineration or production of coal water slurry, meanwhile the low-concentrated component of the desorption liquid is used to prepare sodium hydroxide solution for the adsorption process of the next batch.

Abstract: The invention relates to methods and compositions for genetic transformation of both juvenile and mature citrus. In some embodiments, the invention provides methods and compositions for genetic transformation of citrus using Rhizobia-mediated DNA delivery, and also methods of enhancing the frequency of genetic transformation of mature citrus by any DNA transfer method, including Sinorhizobium. Internodal stem sections prepared from epicotyls of citrus seedlings or freshly emerging shoots of mature citrus plants (e.g., first shoots from buds of mature plants following grafting onto rootstock or very young shoots of mature plants) are preconditioned for transformation by inducing callus formation on an artificial medium. All callus and any developing meristematic regions in immediately adjacent tissue are substantially or completely removed and the preconditioned explants are then transformed by Sinorhizobium or other known methods.

Abstract: The present invention provides compositions and methods for killing or suppressing growth of Gram-negative bacteria that infect, infest or cause disease in plants, including pathogenic, saprophytic and opportunistic microbes that cause disease in plants and food borne illness in people or in animal feed.

Abstract: The present invention discloses a method for advanced treatment of bio-treated coking wastewater, belonging to the field of advanced treatment and recycled use of wastewater. It adopts polymeric ferric sulfate (PFS) and polyacrylamide (PAM) as the flocculant for pre-treatment of bio-treated effluent. After the process of precipitation and filtration, the effluent is guided through an adsorption column filled with environmentally-friendly nano-composites whereby the advanced treatment of the bio-treated coking wastewater is achieved.
