“…Our study did not observe a significant enrichment of these bacterial genera, but the observations may be influenced by the soil type [57]. During the 8 years of alfalfa cultivation, the relative abundance of bacteria involved in autotoxin degradation, such as Flavobacterium, Stenotrophomonas, Brevundimonas, and Massilia [58][59][60], notably decreased in the rhizosphere soil (Figure 6B). Degrading bacteria are known for their crucial ecological functions, breaking down and decomposing organic matter, promoting soil nutrient cycling, and maintaining soil ecological balance [61].…”

Increasing soil salinization can severely restrict local agricultural production. Planting alfalfa is considered an effective measure to ameliorate saline–alkali soil. However, it remains unclear how alfalfa planting years affect the sustained impact on soil and rhizosphere microecology. This study analyzed the effects of alfalfa planted 3, 6, and 8 years ago on soil physicochemical properties and key soil enzyme activities and investigated the rhizosphere microbial community structure and diversity. The results indicate that cultivating alfalfa plants for six years can improve soil physicochemical properties and enhance soil fertility to a certain extent. This is attributed to a higher abundance of plant growth-promoting bacteria, such as Bradyrhizobium and Allorhizobium, as well as degradation bacteria, such as Flavobacterium, Stenotrophomonas, Brevundimonas, and Massilia, in the rhizosphere of alfalfa plants. These microorganisms promote alfalfa growth, improve soil quality, and inhibit the accumulation of autotoxins. This not only maintains high alfalfa yields but also optimizes soil physicochemical properties and enzyme activity, facilitating more effective nutrient cycling and metabolic processes in the soil. However, extending plant growth to 8 years is not beneficial.

“…Glucose is a widely existing carbon source in nature, and the demand for cyclic oxidative phosphorylation of the tricarboxylic acid (TCA) cycle in cells is negatively correlated with the concentration of glucose [31,32]. As shown in Figure 1A,B, glucose and peptone both had a significant effect on the production of 2,3-BD by S. cerevisiae L7 (p < 0.0001), and the production of 2,3-BD first increased and then decreased with increasing concentrations of glucose and peptone, respectively.…”

As a chemical platform, 2,3-Butanediol (2,3-BD) has been widely applied in various industrial fields. In this study, to enhance the production of 2,3-BD by Saccharomyces cerevisiae L7, Plackett–Burman (PB) multifactorial design, the steepest climb test and central composite design (CCD) were employed to optimize the culturing conditions of S. cerevisiae L7. The results show that acetic acid, peptone and glucose were contributing factors for 2,3-BD production. Subsequently, a satisfactory production of 2,3-BD (13.52 ± 0.12 g/L) was reached under optimal conditions, which was 3.12 times higher than before optimization. Furthermore, fed-batch fermentation was carried out under optimized culture conditions, and a higher production and yield efficiency of 2,3-BD were achieved (21.83 ± 0.56 g/L and 0.15 ± 0.01 g/g, respectively) when glucose (20 g/L) and acetic acid (0.2 g/L) were added at 12, 24, 36, 48 and 60 h. Therefore, the production and yield efficiency of 2,3-BD were higher than those without fed-batch fermentation (61.46% and 58.51%, respectively). These results provide good support and a technical foundation for the large-scale industrial production of 2,3-BD by Saccharomyces cerevisiae.
