Gwell is a traditional mesophilic fermented milk from the Brittany region of France. The fermentation process is based on a back-slopping method. The starter is made from a portion of the previous Gwell production, so that Gwell is both the starter and final product for consumption. In a participatory research framework involving 13 producers, Gwell was characterized from both the sensory and microbial points of view and was defined by its tangy taste and smooth and dense texture. The microbial community of typical Gwell samples was studied using both culture-dependent and culture-independent approaches. Lactococcus lactis was systematically identified in Gwell, being represented by both subspecies cremoris and lactis biovar diacetylactis which were always associated. Geotrichum candidum was also found in all the samples. The microbial composition was confirmed by 16S and ITS2 metabarcoding analysis. We were able to reconstruct the history of Gwell exchanges between producers, and thus obtained the genealogy of the samples we analyzed. The samples clustered in two groups which were also differentiated by their microbial composition, and notably by the presence or absence of yeasts identified as Kazachstania servazii and Streptococcus species.

Globally, fermented beverage and condiments are made by using different conventional practices, raw materials, and microorganisms. This paper presents the available literature review on the technology and microbiology of traditional Ethiopian beverages and condiment products. Traditional fermented beverage and condiment products have essential vitamins, minerals, enzymes, and antioxidants that are all enhanced through the process of traditional fermentation practices. In Ethiopia, fermented beverage and condiment products have practiced in a long history. During the production of traditional fermented beverage and condiment products, controlled natural fermentation process with the absence of starter cultures are used to initiate it. Moreover, the preparation of many traditionally fermented beverage and condiment products is still practiced in a household art, thereby a wide variety of fermented beverages and condiments are consumed in Ethiopia. In conclusion, the review discusses the nature of the beverage and condiment preparation, poor traditional household processing, and the extent and limitation of scientific work done so far and suggests some recommendations to limit the problem in Ethiopia.

The paper is concerned with changes of acidity and the amount of microorganism in China Northeast sauerkraut fermentationin.It studies the effect of lactic acid bacteria, culture temperature and the concentration of sodium chloride on sauerkraut acidity ,microbial number, vitamin C and nitrite content .Methods of natural traditional fermentation sauerkraut and artificial inoculating lactic acid bacteria fermentation sauerkraut are compared,the results show artificial inoculating fermentation sauerkraut can effectively prevent the growth of harmful bacteria and inhibit formation of carcinogens such as nitrite,avoid some shortcomings in Chinese cabbage natural fermentation process.
