“…At present, the published studies (21,22) refer to the extraction of collagen from fish skin for application in the rape production in the final stage of vegetation, to cover the silicves and to prevent the dehiscence. In these reference works, only the collagen hydrolysates from fish skin has been tested also in rapeseed germination.…”

In the present research biocomposites based on extracts of collagen and keratin recovered from the leather industry by-products were made and the specific properties for applications in agriculture and industry were studied. To this aim, collagen and keratin have been extracted from bovine leather and sheep wool by-products and have been added and crosslinked with recognized compounds for reduced environmental impact (glycerol, vegetable tanning extract, essential oils with fungicidal properties and insecticides). The biocomposite properties were evaluated on the basis of complex analytical investigations on chemical structure, texture, contact angle, mechanical resistance, water vapor permeability and water absorption, biodegradation, germination and plant biomass growth. The biocomposites have demonstrated pelliculogenic properties and nitrogen controlled release to stimulate germination and nutrition of rape seedlings, which promotes them for agricultural applications, but also other surface properties have been identified, for industrial applications, for example in leather finishing for special destinations. Addition of odorous principles with controlled release recommends this type of biocomposites for environmentally friendly products, maintenance of cleaning, etc.

“…Based on the results of studies that showed that protein extracts do not have toxic or genotoxic effects and do not adversely affect eukaryotic cells and the soil ecosystem (Corte et al, 2014), their applications were extended to the field of agriculture, particularly soil remediation (Zainescu et al, 2010) and fertilization of crops (Sirbu et al, 2009). The most recent studies have been focused on obtaining collagen hydrolysates from tanned leather by-products for the fertilization of horticultural crops (Gaidau et al, 2009, Pati et al, 2015, grain seed treatment to stimulate germination and reduce amounts of insecticide-fungicide (Gaidau et al, 2013), the fertilization of wheat and rice crops (Coelho et al, 2015), the use of fish skin collagen extracts to increase the yield of rape by stimulating growth and reducing silique dehiscence (Gidea et al, 2017), the use of bovine hide collagen hydrolysate in the foliar treatment of vines to alleviate the effects of iron deficiency due in particular to calcareous soils (Tudor et al, 2017).…”

The main property of collagen polydispersions is their molecular profile, dependent on both raw materials origin and the extraction process. The paper presents collagen extracts from leather byproducts, by thermal and enzymatic hydrolysis at alkaline pH with improved properties by additivation with glycerol and crosslinking with Tara tannin extract. Structural analysis by Dynamic Nuclear Magnetic Resonance Spectroscopy showed manifestations which may be attributed to the interaction of glycerol and Tara tanning extract with polypeptide chains and to the role of glycerol as plasticizer, partially compensated by the addition of Tara crosslinking. New combinations of crosslinked and uncrosslinked collagen polydispersions were applied in cereals and legume seed treatment, so as to provide free amino acid content immediately available for stimulation of germination and a layer of polypeptides that would slowly release amino acids for growth stimulation. The results were quantified by an increase in cereal seed germination of over 15% and a much more pronounced development of plants, which have reached lengths over 10% higher compared to untreated seeds. For the most of legumes, the new treatment led to development of total biomass (root and cotyledons) and to a higher permeability for the water imbibition of the seeds.
