Resumen:
The current and growing pollutions (air, water and soil) are, in part, the result of inadequate management of municipal solid waste (MSW). The relation between Public Health - storage, collection and improper disposal of solid waste, has encouraged several studies, and these results have attributed to this interrelationship the spread of over twenty human and animal diseases. The term "single cell protein (SCP), is referred to the microbial biomass used as a dietary additive. It has high nutritional value because of its high protein content of biological quality (presence, in general, all essential amino acids), of vitamins and lipids. The aim of this work was focused on the use of nutrients contained in organic waste, conduced to design culture media for microbiological assays and, to produce single cell proteins for animal feed. The nutritional quality (percentage values) obtained after processing the food debris allowed infer a good chance for microbial growth, because carbohydrate (1.00 ± 0.03 %) and protein (0.77 ± 0.18) levels were not contained as limiting growth factors. The microorganisms considered to study the effectiveness between both culture media, Food Waste and LAPTg, were: Lactobacillus plantarum ATCC 7469, Lactobacillus rhamnosus, Enterococcus, Staphylococcus aureus, Shigella sonnei, . In all cases, the CFU/mL obtained from Food Waste (FW) and LAPTg culture media, showed not significant statically differences (p>0,05). In addition, to determine the behavior of Food Waste (FW) and LAPTg culture media, showed not significant statically differences (p>0,05), comparative studies involving Molasses broth (MB), FW Broth and Basal Broth (BB), were carried out. The biomass yield calculated at 24 h, from FW Broth was 13% lower than from the MB. The FW Broth, despite showing lower biomass yield, statistically significant (p
