This work addresses how a pre-treatment involving biomass ash influences the poultry effluent’s bioremediation using three microalga strains, such as Chlorella vulgaris, protothecoides and Tetradesmus obliquus. The undiluted effluent served culture medium for growth, both in batch semi continuous modes, remediation efficiency production yield were quantified. combination strategy mode, allowed ...

Zarzecka K., Gugała M. (2018): The effect of herbicides and biostimulants on sugars content in potato tubers. Plant Soil Environ., 64: 82–87. The objective of the present work was to determine changes in total sugars, reducing sugars and sucrose content in potato tubers under conditions involving an application of biostimulants and herbicides. Research material included table potato tubers obta...

Few studies have focused on the role of compatible solutes in changing the microbial community structure in bioaugmentation systems. In this study, we investigated the influence of trehalose as a biostimulant on the microbial community in tetrahydrofuran (THF)-treated wastewater bioaugmentation systems with Rhodococcus sp. YYL. Functional gene profile changes were used to study the variation in...

Field and laboratory experiments were carried out in 2012-2013, aimed at evaluating the influence of new products stimulating plant growth based on amino acids on crop yield, characteristics of grain and content of macro- and micronutrients in winter wheat (Triticum aestivum L.). The tests included two formulations produced in cooperation with INTERMAG Co. (Olkusz, Poland)-AminoPrim and AminoHo...

Drought adversely affects many physiological and biochemical events of crops. This research was conducted to investigate the possible effects biostimulants containing plant growth-promoting rhizobacteria (PGPR) on growth parameters, chlorophyll content, membrane permeability (MP), leaf relative water content (LRWC), hydrogen peroxide (H 2 O ), proline, malondialdehyde (MDA), hormone antioxidant...
