Production of dietary feed supplements enriched in microelements in a pilot plant biosorption system

Abstract

In this work, biosorption was used as a method to enrich biomass (soybean meal) with microelements [such as Zn(II), Cu(II), Mn(II) and Fe(II)] that are essential in livestock nutrition to produce dietary feed supplements. The biosorption process was carried out in a specially designed pilot plant system with two-column reactors according to the principles of the eco-friendly effluent-free technology. The applicative parts of products and innovative biological feed supplements were produced for zootechnical tests on animals (hens, goats and fatteners). Multielemental analysis showed a multiple increase in the content of each microelement in the soybean meal after biosorption [of Zn(II)-168 times, Cu(II)-179 times, Mn(II)-62 times and Fe(II)-50 times]. The process was analyzed in terms of technological indicators and preliminary economic analysis, including the cost of materials, labor costs and depreciation of the equipment used. It was found that the cost of supplementation of 1 kg of feed for laying hens and fattening pigs with the new preparation enriched with Cu(II) and manufactured on a technical scale was around $0.393.

Cladophora glomerata enriched by biosorption with Mn(II) ions alleviates lipopolysaccharide‐induced osteomyelitis‐like model in MC3T3‐E1, and 4B12 osteoclastogenesis

“…Thus, biosorption process can be applied in order to improve the bioavailability of the microelements for the animals while combining the nutritional and curative properties of the used biomasses. 21,22 In that context, the methanolic extract obtained from C. glomerata enriched with Mn(II) ions via biosorption process was applied to a model of LPS-induced osteomyelitis on MC3T3 pre-osteoblasts cell line, as well as on the osteoclastogenesis process induced on 4B12 cells in the present investigation, with the goal of combining the beneficial effects of manganese on bone metabolism, and the anti-inflammatory, antiapoptotic and antioxidant effects of C. glomerata extract.…”

How the Basidiomycetes Respond to Biogenic Aspartate-Bound Metals(ii) of Variable Valency in Growth Media

“…Органическая форма микроэлементов обладает значительными преимуществами перед неорганическими прекурсорами (9)(10)(11), кроме того, при использовании в виде неорганических солей металлы малодоступны для утилизации организмами (12)(13)(14). Конъюгация металлов(II) (в частности Cu, Mn, Fe, Zn, Co) с эссенциальными аминокислотами представляется решением проблемы биодоступности (15,16) благодаря химическим процессам комплексообразования.…”
