As an important characteristic crop in China, sweetpotato plays an important role in the intake and supplement of nutrients. The saccharification characteristics of sweetpotato determine the edible quality and processing type. Exploring the saccharification characteristics of sweetpotato is of great significance to the selection of processing materials and the formation mechanism of service quality, but there are few relevant studies. A comparison study of two high saccharification varieties (Y25 and Z13) and one low saccharification variety (X27) was conducted to analyze their storage roots physical and chemical properties. The results show that the dry matter content, starch, and amylose content of Y25 and Z13 were significantly different from those of X27. Furthermore, the total amylase activity was significantly higher than that of X27. On the other hand, the starch gelatinization temperature was significantly lower than that of X27. The starch reduction in Y25 and Z13 is four times more than that in X27, and the maltose content of Y25 and Z13 is more than two times that of X27. Finally, the scores of sensory evaluation and physiological sweetness were significantly higher than those of X27. The results provide a theoretical basis for understanding the saccharification characteristics of sweetpotato varieties and are of guiding significance for the selection of sweetpotato parents.

To investigate the bacterial community structure and physicochemical characteristics of different types of Daqu in the Binzhou region, this study employed traditional pure culture methods, high-throughput sequencing technology, and conventional physicochemical assays for analysis. The research results indicate that Enterococcus faecium and Bacillus licheniformis emerged as the main LAB and Bacillus species in Daqu from Binzhou region, respectively. In addition, high-throughput sequencing revealed significant differences in bacterial community structure between the two types of Daqu (P < 0.

In order to establish an efficient microbial transformation platform based on seaweed feedstocks, experiments were performed to isolate a salt-tolerant strain capable of producing alginate lyase and 2,3-butanediol (2,3-BDO). Its physiological and biochemical characteristics, carbon source utilization, and product synthesis capabilities were investigated, and then the process for co-producing alginate lyase and 2,3-BDO from Laminaria japonica was optimized. Results showed that the isolated strain was identified as Vibrio alginolyticus, which was capable of utilizing multiple carbon sources to produce alginate lyase and 2,3-BDO even in the presence of 5 % NaCl.

Article Synopsis
- This study developed a cleaner version of medium-high-temperature Daqu (XQ) using specific microbial inoculations and compared its features with traditional Daqu (CQ).
- Results revealed that XQ exhibited superior liquefaction, saccharification, esterification activities, and moisture content compared to industry standards.
- Flavor analysis showed both Daqu types had similar profiles dominated by esters, alcohols, and acids, while microbial sequencing identified specific fungi and bacteria unique to each type, providing a foundation for creating safer fermented foods.
