Background: Plant growth-promoting bacteria (PGPB) benefit plant growth and development via different direct and indirect mechanisms. However, our knowledge about rhizosphere soil response at different plant growth stages to diverse PGPB application in sugarcane is limited. In this study, four strains of bacteria genera (Gluconacetobacter diazotrophicus PAL5, Streptomyces chartreusis WZS021, Bacillus spp. CA1, and Pseudomonas mosselii CN11) were inoculated into two sugarcane varieties (B8, ROC22) as single or mixture in a pot planting experiment. The effects of single or combined application of PGPB on nitrogen metabolism, agronomic traits, rhizosphere soil chemical and biological properties and microbial community were surveyed. Results: It was found that different treatments had different promotion ways for different sugarcane varieties and rhizosphere soils. PAL5 and CA1+CN11 significantly improved the nitrogen fixation efficiency of sugarcane, while WZS021 treatment enhanced phosphorus (available phosphorus and alkaline phosphatase). High-throughput sequencing (HTS) analysis revealed that Proteobacteria, Firmicutes, Chloroflexi, and Actinobacteria were the main microbial community phylum components. Correlation analysis indicates that phyla Proteobacteria and Bacteroidota played a key role in the nitrogen cycle of the soil-microbe-plant interaction system, while phylum Firmicutes had a crucial role in the phosphorus cycle. And we found that, In the varieties with weak bacterial species in the rhizosphere soil, the addition of the composite strain had the best effect, while in the varieties with rich bacterial species, the addition of the composite strain may have the exclusion phenomenon, which was not as good as the addition of the single dominant strain. Conclusions:The PGPB had excellent activities, such as nitrogen fixation, phosphorus and potassium solubilization, which could promote plant growth by decomposing soil nutrients. The inoculated strains can positively enrich the beneficial bacteria in sugarcane. However, there were variations in the quantities of these promoted properties in the treatments with different bacterial strains and sugarcane varieties. It was found that soil-disadvantaged and inoculum-specific bacteria were more favorable to plant development. The considerable variation in soil microbe provides a knowledge base and an experimental system for further mining and utilization of microbial strains.

“…These studies have shown that microplastics accumulate and distribute in the gastrointestinal tract, gills, and fish muscles. Ingestion of microplastics in marine animals has been linked to alterations in gastrointestinal tract physiology, immune system depression, oxidative stress, cytotoxicity, differential gene expression, and growth inhibition (Oliviero et al 2019 ; Meaza et al, 2021 ; Kedzierski et al 2018 ; Nabi et al 2019 ; Amin et al 2020 ; Ugwu et al 2021 ). These findings are confirmed by Danopoulos et al ( 2021 ), who reported on the biological endpoint caused by microplastics to different human cells.…”

Microplastic pollution is becoming a major issue for human health due to the recent discovery of microplastics in most ecosystems. Here, we review the sources, formation, occurrence, toxicity and remediation methods of microplastics. We distinguish ocean-based and land-based sources of microplastics. Microplastics have been found in biological samples such as faeces, sputum, saliva, blood and placenta. Cancer, intestinal, pulmonary, cardiovascular, infectious and inflammatory diseases are induced or mediated by microplastics. Microplastic exposure during pregnancy and maternal period is also discussed. Remediation methods include coagulation, membrane bioreactors, sand filtration, adsorption, photocatalytic degradation, electrocoagulation and magnetic separation. Control strategies comprise reducing plastic usage, behavioural change, and using biodegradable plastics. Global plastic production has risen dramatically over the past 70 years to reach 359 million tonnes. China is the world's top producer, contributing 17.5% to global production, while Turkey generates the most plastic waste in the Mediterranean region, at 144 tonnes per day. Microplastics comprise 75% of marine waste, with land-based sources responsible for 80–90% of pollution, while ocean-based sources account for only 10–20%. Microplastics induce toxic effects on humans and animals, such as cytotoxicity, immune response, oxidative stress, barrier attributes, and genotoxicity, even at minimal dosages of 10 μg/mL. Ingestion of microplastics by marine animals results in alterations in gastrointestinal tract physiology, immune system depression, oxidative stress, cytotoxicity, differential gene expression, and growth inhibition. Furthermore, bioaccumulation of microplastics in the tissues of aquatic organisms can have adverse effects on the aquatic ecosystem, with potential transmission of microplastics to humans and birds. Changing individual behaviours and governmental actions, such as implementing bans, taxes, or pricing on plastic carrier bags, has significantly reduced plastic consumption to 8–85% in various countries worldwide. The microplastic minimisation approach follows an upside-down pyramid, starting with prevention, followed by reducing, reusing, recycling, recovering, and ending with disposal as the least preferable option.

“…For biochemical evaluation 10 fish were transferred to each aquarium (25 × 25 × 25 cm dimension) containing 10 L (liter) of water. Fish were treated for 24 and 48 h with LC 0 doses of malathion (1.425 ppm), chlorpyrifos (0.125 ppm) and λ-cyhalothrin (0.0039 ppm) (Amin et al, 2020). Separate aquarium was used for each pesticide along with three control groups (water without the addition of pesticides).…”

Organophosphates and synthetic pyrethroid pesticides are used in residential areas and agriculture, discharge into environment, may cause unpredictable toxicity to non-targeted aquatic organisms. The current study aims to assess the effect of these pesticides on the transaminases, glutamate oxaloacetate transaminase and glutamate pyruvate transaminase enzymes activity in brain and gills of Oreochromis niloticus. Fish were exposed for 24 and 48 h (hours) to the LC0 (non-lethal concentrations) of the malathion, chlorpyrifos and λ-cyhalothrin, respectively. For biochemical assay, a spectrophotometer was used. Glutamate oxaloacetate transaminase activity in brain and gill was significantly (p <0.05) elevated and inhibited, respectively, except in 48 h treated samples. The highest (+258%) and lowest (+8.9%) enhancement in this activity was noted in chlorpyrifos and malathion treated gill samples, respectively. The glutamate pyruvate transaminase activity was significantly (p <0.05) enhanced in all treated samples except in 24 h malathion treated brain. The highest (+340.7%) and lowest (+27%) enhancement in this level was recorded in malathion and chlorpyrifos exposed brain and gills samples. Therefore, it is suggested that both these assessments in fish different organs could be used as a useful biomarker to detect environmental pollution. Thus, the alterations in transaminases activity indicated that the tested pesticides are highly toxic to the health of aquatic organisms and should be periodically and regularly monitored in the environment to reduce pollutant stress on non-target biota, particularly fish.
