These systems have appeared from different research works always taking in account the environmental sustainability. It is mentioned that the agave bagasse can be used for animal feeding, for the elaboration of compound materials, as an element for agricultural and hydroponic vegetables cultivation purposes, and also as a means to treat biosolids, vinasses, and bagasses of slaughterhouses and tanneries.展开更多

Tomatoes were grown in 28-L pots for 106 days under a drip irrigation system with a hydroponic crop nutrient solution. The average production of grape tomatoes was 338.9, 358.9, and 325.7 g/pot/cut for each of the substrates studied, and no significant difference was observed between treatments (p > 0.5). The mean of numbers of grape tomatoes were 34.6, 38.8, and 34.2/pot/cut for each of the substrates studied, and no significant difference was observed between treatments (p > 0.5). The mean weight of individual grape tomatoes was about 10.4 g for all of the substrates tested. These results confirmed the notion that a composted agave bagasse substrate could replace an expensive imported substrate. The remaining challenge is to produce agave bagasse substrate commercially, because to date, agave bagasse substrates have only been produced on a pilot scale for testing. Therefore, it is necessary to implement a stabilized process for producing agave bagasse at a commercial level. This process must consider economic production costs and market value to ensure that the product is competitive with other substrates typically used in soilless crops.展开更多

The fish was normally fed and had a normal reproductive behaviour. After spontaneous death occurred at an advanced age, the fish was submitted for necropsy examination, which revealed the presence of an oval, 1 cm× 0.5 cm× 0.5 cm in size, cystic structure containing clear amber fluid, located in the coelomic cavity, in place of the spleen. Histopathological examination revealed multiple cystic spaces empty or filled with a slightly eosinophilic, homogenous, proteinaceous material, and lined by flattened, vimentin-positive endothelial-like cells. Residual parts of splenic tissue were also admixed with cystic spaces, suggesting a final diagnosis of cystic lymphangiomatosis of the spleen, which has not been previously described in fish. This is the first report of multiple, life-compatible, congenital physical deformities in association with splenic lymphangiomatosis inZoogoneticus tequila.展开更多
