High-throughput sequencing of the microbial diversity of roasted-sesame-like flavored Daqu with different characteristics.

The purpose of this experiment was to analyze the microbial community diversity in three Daqu samples displaying different characteristics in the same Daqu fermentation chamber. A high throughput sequencing technique was used to detect the microbial abundance and diversity in these Daqu samples. Of the three samples, the microbial diversity in the Black sample (sample B) was significantly higher than in the other two.

Polymers and protein-associated vesicles for the microencapsulation of anthocyanins from grape skins used for food applications.

Background: Anthocyanins were extracted from grape skins by a combination of ethanolic-ultrasonic assisted methods and were then encapsulated by freeze-drying in soy phosphatidylcholine vesicles with the addition of different polymers, such as pectin, acacia gum, and whey protein isolate. The goal of this research was to microencapsulate anthocyanin compounds extracted from grape skins, to characterize the stability and behavior of the vesicles and then to use them to obtain a new light formulated mayonnaise.

Results: The particle size ranged from 900 nm in the control condition to 250 nm in vesicles loaded with whey proteins.

High-throughput sequencing of microbial community diversity in soil, grapes, leaves, grape juice and wine of grapevine from China.

In this study Illumina MiSeq was performed to investigate microbial diversity in soil, leaves, grape, grape juice and wine. A total of 1,043,102 fungal Internal Transcribed Spacer (ITS) reads and 2,422,188 high quality bacterial 16S rDNA sequences were used for taxonomic classification, revealed five fungal and eight bacterial phyla. At the genus level, the dominant fungi were Ascomycota, Sordariales, Tetracladium and Geomyces in soil, Aureobasidium and Pleosporaceae in grapes leaves, Aureobasidium in grape and grape juice.

Complete genome sequence of Bacillus amyloliquefaciens B15 isolated from grape skin, a strain of strong inhibitory activity against fungi.

Bacillus amyloliquefaciens B15 is a Gram-positive, plant-associated bacterium which shows strong antifungal activity, isolated from grape skin in Xinjiang, China. The genome of B. amyloliquefaciens B15 comprises a 4,006,754bp long circular chromosome containing 3991 protein coding genes and 109 RNA genes.

Short communication: effect of milk and milk containing Lactobacillus casei on the intestinal microbiota of mice.

BALB/c mice were fed milk or Lactobacillus casei BL23 in milk for 14d and fecal samples were collected at d 0, 4, and 7 as well as 1 and 8d after the last administration. According to high-throughput DNA sequencing of the 16S rRNA genes extracted from the fecal microbiota, the bacterial diversity in the fecal samples of all mice increased over time. After 14d of administration, the consumption of milk and milk containing L.

Microbial diversity and dynamics of microbial communities during back-slop soaking of soybeans as determined by PCR-DGGE and molecular cloning.

Tempe is a traditional fermented food in Indonesia. The manufacture process is quite complex, which comprises two stages, preparatory soaking of soybeans and fungal solid state fermentation. Daily addition of previous soak water (back-slopping) during the soybean soaking step is considered to be crucial in the manufacture of high quality tempe.

Microbial composition during Chinese soy sauce koji-making based on culture dependent and independent methods.

Koji-making is a key process for production of high quality soy sauce. The microbial composition during koji-making was investigated by culture-dependent and culture-independent methods to determine predominant bacterial and fungal populations. The culture-dependent methods used were direct culture and colony morphology observation, and PCR amplification of 16S/26S rDNA fragments followed by sequencing analysis.
