Study On The Production Of Bacteria Protein Feed By Tomato Waste Residue

Tomato waste residue is the residual wastes of tomato puree processing. With the increasing demand for tomatoes and the rapid development of the tomto processing industry all over the world more and more tomato waste residue are produced. Now good ways to handle the tomato waste residue have not come into use which affects the development of the tomto industry and greatly pollute the environment. It will effectively promote the development of tomato industry. If we can seek for a more scientific and effective way to deal with tomato waste residue to realize the recycling of waste residue and according with the requirement of sustainable development.The tomato waste residue was studied as a test material, Trichoderma viride, Aspergillus niger, candida tropicalis and candida utilis were used for fermenting fungal, chose wheat bean as auxiliary material, add inorganic nitrogen and inorganic salts, and confirmed the feasibility of experiment by inhibition. In order to ensure the best combination, proportion, time and number of bacteria we systematically studied the change of crude protein and suger content after he fermentatonof single or multiple bacterial. By single fctor test and perpendicular test dieffrent nitrogen soure and inorganic salts are studied to show the impaetion on the study; The proportion of tomato peels to offal, tempreture, pH, time were also determined.The test result showed that used tomato waste residue to production protein feed is feasible and tomato waste residue’s nutrition can meet the growth of bacteria. By single fungl fermentation we can see that the best bran addition amount is 15%, and aspergillus niger is better than trichoderma viride as fermenting fungal. The quantity of pectinase and cellulose produced by aspergillus niger are 6229.1 μg/(h-g) and 504.7 μg/(h-g) which is 1.1 times than trichoderma viride’s. when the proportion of trichoderma viride, aspergillus niger to candida tropicalis is 1:2:6 we can see the best result and the protein’s content is 35.01%.The experiment results show that the best combination of auxiliary material add amount can be drown as follows:tomto waste residue 75 g, potassium phosphate dibasie 0.1 g, magnesium sulfate 0.3 g, caleium peprhosphate 0.4 g, Ammonium sulfate 0.5 g, Uera 0.4 g. Stuided the erfmenting conditions, we found that when the fermentation temperature is 26℃, the water content is 70%, the original pH is 4, fermentation time is 4d, the crude Protein content after fermentation can reach to the highest number.The experiment which determined the proeess of used the tomato waste residue to produce protein feed not only solves the problem of tomato waste residue waste and environmental pollution, but also provide the new type of microbial protein feed. The technique is simple enough to operate and lower cost to procucton which can be seen as a sustainable development planning.
