Abstract

The presented study assessed the effect of bovine (BC) and fish (FC) waste-derived collagen, poly(hexamethylenebiguanide) hydrochloride (PHMB) and waste dolomite on the emergence of seedlings, growth and development of pea (Pisum sativum L. ‘Lasso’) plants. The seed coating method was used to apply the binding agents. Some of the studied agents were showed to significantly affect the index of emergence velocity (IEV) and of emergence synchrony (IES), but not the final emergence percentage (FEP). The results showed that treatment of the pea seeds with BC, FC and PHMB had a slightly positive effect on plant growth, whereas negative effects of dolomite were observed, i.e., detrimental differences in morphological traits of stipules. Moreover, BC, FC and PHMB improved maximal efficiency of PSII (FV/FM) and did not negatively influence chlorophyll content. Analyses demonstrated positive effects of FC and PHMB and negative ones of BC and dolomite on elemental composition of roots and shoots of the studied plant species. We suggest that the FC and PHMB can be used as promising agents for improvement of plant growth, whereas usage of BC and dolomite should be limited.

fresh weight (FW) and dry weight (DW) of both roots and shoots of all dolomite-treated plants (0 + D, Bovine Collagen (BC) + D, Fish Collagen (FC) + D, poly(hexamethylenebiguanide) hydrochloride (PHMB) + D) were significantly lower in comparison with the respective groups not subjected to dolomite treatment (0, BC, FC, PHMB) (Figure 1)
FW and DW of both roots and shoots were dependent on dolomite, but not on binding agent or interaction of the studied factors (Table S3)

Summary

Introduction

Published: 21 May 2021The leather industry plays one of the major roles in the global economy. Of solid wastes arise from the processing of raw hides to leather [2]. The main task of the leather industry is to obtain physically and chemically stable material. Leather processing generates a biodegradable polymer material (collagen) as a side product of the tanning industry [3]. The main sources of collagen in the leather industry are wastes from tanning and processing of the leather, i.e., raw trimmings, fresh and limed garments and splits. Valuable collagen products are typically extracted from bovine hide off-cutting wastes [4]. Another industrial source of collagen is marine fisheries, which generate a large amount of waste, including viscera and fish scales [5]. Collagen of animal origin has wide applications in food, biomedical and pharmaceutical industries [6]
