A comparative pot study was performed to assess the toxic effects of copper (Cu) and/or zinc (Zn) contaminated wastewater (WW) irrigation on the growth, physiology, and element concentration of wheat grown for two months. The treatments included irrigation with uncontaminated wastewater (WW) as control, Cu-contaminated WW (CuWW), Zn-contaminated WW (ZnWW), and Cu + Zn contaminated WW (CuZnWW) in a completely randomized design. Compared to ZnWW, irrigation with CuWW or CuZnWW had severe effects on growth, physiology, and mineral absorption by wheat.

Actinobacteria are widely used in aerobic composting of straw waste because of their good degradation effect on lignocellulose. However, there are few studies on the degradation effect of on straw. In this study, six laboratory-scale treatments were conducted: corn straw composting with inoculation (CSI), rice straw composting with inoculation (RSI), and wheat straw composting with inoculation (WSI).

The widespread concern over nanoplastics (NPs) has prompted extensive research into their environmental impact. Concurrently, the study examined the combined toxicity of PS NPs and cadmium (Cd) on wheat. As indicated by the results of in situ Micro-ATR/FTIR, the aging process of PS NPs (50 nm) led to an increase in carbonyl and hydroxyl groups on their surface, enhancing hydrophilicity and consequently, the adsorption capacity for Cd.

Background: Heavy metal contamination, particularly from lead (Pb), poses a significant threat to plant agriculture worldwide, adversely affecting growth, physiological functions, and yield. Signalling molecules such as calcium and salicylic acid are known to mitigate various stresses in plants, prompting this study to explore their interaction with Pb stress in wheat.
Methods: A pot experiment was conducted in which wheat grains were primed with either distilled water, 5 mM calcium (Ca), or 0.
Spawn-based pellets of Pleurotus ostreatus as an applied approach for the production of laccase in different types of water.

In recent years, oxidoreductase enzymes such as laccases have received considerable attention for their ability to degrade and eliminate organic micropollutants from contaminated water in a process known as enzyme-based wastewater treatment. Thus, methods to produce high laccase activity in water are a point of focus, with white-rot fungi being highlighted as a tool in this context. This study, therefore, explored the applied approach of direct addition of mushroom spawn of the white-rot fungi Pleurotus ostreatus into water and its potential for laccase production under different conditions.
