Rhodocyclus Gelatinosus

Four cultures of photosynthetic bacteria isolated from poultry slaughterhouse wastewater were identified as Rhodocyclus gelatinosus based on the following properties: reddish color of cultures in synthetic medium, presence of motility, slightly curved Gram-negative rods morphology, gelatin liquefying activity, utilization of citrate as carbon source and production of bacteriochlorophyl a and carotenoids of the spirilloxanthin alternative series. R. gelatinosus may represent a source of nutrients and pigments with application in poultry feed.

Seafood Processing

Large quantities of wastes are generated in the processing of seafood such as shellfish, crustaceans and finfish. These materials contain appreciable amounts of plant nutrients which may be useful in cropping programs. Under some conditions the waste materials can be directly applied to soil but in other situations stabilization may be necessary. The method of stabilization will influence the availability of nutrients in various cropping programs. Composting with wood can effectively stabilize the waste but the slow mineralization of organic N can limit the usefulness of the compost. Combining the waste with calcium oxide (CaO) or hydrated lime [Ca(OH)2] can produce a stable material with good nutrient availability. If application rates of various wastes are based on their nutrient content, the nutrient requirement of specific crops, and the heavy metal concentrations, then potential environmental problems associated with excess nutrient and heavy metal loadings can be minimized. Application of these materials to land can effectively supply nutrients to crops and minimize environmental damage due to inappropriate methods of disposal. Key words:Seafood waste, composting, lime stabilization, crop nutrients

With nitrite or nitrate nitrogen as electron acceptor in the high salt conditons, halophilic denitrifying bacteria can transfer nitrite or nitrate to nitrogen, thereby purifying the high-salt wastewater. Halophilic denitrifying bacteria play an important role in the carbon and nitrogen removal of saline wastewater, such as petroleum, chemical industry, seafood processing and seafood farming. This article dissussed halophilic denitrifying bacteria screening, the main types and the corresponding morphological characteristics, then we focused on the research progress of main factors of halophilic denitrifying bacteria’s growth and nitrogen removal. Finally put forward the current problems of the research and development trend of halophilic denitrifying bacteria.
