Abstract:
The structure of microbial communities in a typical Italian-style salami, including bacterial and fungal diversity, was investigated by high-throughput sequencing technology. A total of 6 phyla, 7 classes, 19 orders, 20 families and 28 genera were obtained from 16S rDNA sequences, and a total of 2 phyla, 4 classes, 4 orders, 5 families, 10 genera and 12 Species were obtained from 18S rDNA sequences. The core microbiota was composed of Staphylococcaceae, representing up to 97.52% of the total 16S rRNA, and Penicillium digitatum, accounting for 99.74% of the total classified 18S rRNA. Lactobacillales and Saccharomycetales were detected with a quite low proportion of 1.71 and 0.007%, respectively. This study contributes to the knowledge of the microbial diversity involved in salami and presents high-throughput sequencing as a useful tool to evaluate microbial diversity and monitor the food-borne pathogens in fermented sausage.

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
