“…The isolated bacteria FN2 also showed better tolerance of the saline–alkali condition than the purchased Azospirillum brasilense ( Figure S2b ). In Dongying city, the moderate saline–alkali soil (salinity of 2.0–4.0 g/kg and pH between 8.09–8.35) accounted for more than half of the land area [ 39 ]. The isolated bacterial strains survived in this kind of soil after long-term natural selection, which could adapt to high saline–alkali conditions better than the other purchased strains [ 19 ].…”

The addition of functional bacteria (FB) is low-cost and is widely applied in saline–alkali soil remediation, which may gradually become ineffective due to inter-specific competition with indigenous bacteria. To improve the adaptability of FB, the target FB strains were isolated from local saline–alkali soil, and the combined effects of FB and biochar were explored. The results showed that FB isolated from local soil showed better growth than the purchased strains under high saline–alkali conditions. However, the indigenous community still weakened the function of added FB. Biochar addition provided a specific niche and increased the relative abundance of FB, especially for Proteobacteria and Bacteroidota. As a result, the co-addition of 10% biochar and FB significantly increased the soil available phosphorus (AP) by 74.85% and available nitrogen (AN) by 114.53%. Zea Mays’s growth (in terms of height) was enhanced by 87.92% due to the decreased salinity stress and extra nutrients provided.

The expression of the soybean Bowman–Birk proteinase isoinhibitor DII (BBI-DII) gene and the inducible activity of its promoter were studied under salt, drought, low temperature, and abscisic acid (ABA) exposure conditions. The BBI-DII gene was induced by salt, drought, low temperature, and ABA, and the relative expression levels at the peak were 103.09-, 107.01-, 17.25- and 27.24-fold, respectively, compared with the untreated control. The putative promoter, designated BP1 (− 1255 to + 872 bp), located 5’-upstream of the BBI-DII gene was cloned. The expression of the GUS gene in pCAM-BP1 transgenic tobacco plants was highest at 5 h after treatment with salt, drought, low temperature and ABA, especially under salt and drought. Using histochemical staining and fluorescence analysis of GUS, BP1 activity under salt and drought conditions after 5 h was 1.03 and 1.07-fold, respectively, compared with that of the CaMV35S promoter. Based on a 5’ deletion analysis, the segment (+ 41 to + 474 bp) was the basal region that responded to salt and drought, whereas the segment (− 820 to + 41 bp) was the area that responded to increased salt and drought activity. The BP2 (− 820 to + 872) activities were 0.98- and 1.02-fold compared with that of BP1 under salt and drought conditions and was 435 bp shorter than BP1. The salt- and drought-inducible activities of the BP2 promoter in the roots, stems, and leaves of transgenic tobacco plants were stable. Taken together, BP2 is more suitable than the BP1 promoter for the study and molecular breeding of stress-resistant soybean plants.

Conversion of biomass to biofuels and life cycle assessment: a review

et al. 2021

The global energy demand is projected to rise by almost 28% by 2040 compared to current levels. Biomass is a promising energy source for producing either solid or liquid fuels. Biofuels are alternatives to fossil fuels to reduce anthropogenic greenhouse gas emissions. Nonetheless, policy decisions for biofuels should be based on evidence that biofuels are produced in a sustainable manner. To this end, life cycle assessment (LCA) provides information on environmental impacts associated with biofuel production chains. Here, we review advances in biomass conversion to biofuels and their environmental impact by life cycle assessment. Processes are gasification, combustion, pyrolysis, enzymatic hydrolysis routes and fermentation. Thermochemical processes are classified into low temperature, below 300 °C, and high temperature, higher than 300 °C, i.e. gasification, combustion and pyrolysis. Pyrolysis is promising because it operates at a relatively lower temperature of up to 500 °C, compared to gasification, which operates at 800–1300 °C. We focus on 1) the drawbacks and advantages of the thermochemical and biochemical conversion routes of biomass into various fuels and the possibility of integrating these routes for better process efficiency; 2) methodological approaches and key findings from 40 LCA studies on biomass to biofuel conversion pathways published from 2019 to 2021; and 3) bibliometric trends and knowledge gaps in biomass conversion into biofuels using thermochemical and biochemical routes. The integration of hydrothermal and biochemical routes is promising for the circular economy.
