Species Diversity of Lactic Acid Bacteria from Chilled Cooked Meat Products at Expiration Date in Belgian Retail
SPECIES DIVERSITY OF LACTIC ACID BACTERIA FROM CHILLED COOKED MEAT PRODUCTS AT EXPIRATION DATE IN BELGIAN RETAIL Wim Geeraerts1, Vasileios Pothakos1, Luc De Vuyst1 and Frédéric Leroy1 1 Research Group of Industrial Microbiology and Food Biotechnology (IMDO), Faculty of Sciences and Bioengineering Sciences, Vrije Universiteit Brussel, Pleinlaan 2, B-1050 Brussels, Belgium [email protected] Abstract – The bacterial communities of a wide (e.g., salt) and additives (e.g., sodium lactate). variety of chilled cooked meat products (29 different However, current practices often intend to reduce products), originating from pork and poultry, were the amount of salt and additives in view of subjected to extensive sampling.

Abstract: This study evaluated the microbial quality, safety, and ecology of a retail delicatessen Galotyri-like fresh acid-curd cheese traditionally produced by mixing fresh natural Greek yogurt with ‘Myzithrenio’, a naturally fermented and ripened whey cheese variety. Five retail cheese batches (mean pH 4.1) were analyzed for total and selective microbial counts, and 150 presumptive isolates of lactic acid bacteria (LAB) were characterized biochemically. Additionally, the most and the least diversified batches were subjected to a culture-independent 16S rRNA gene sequencing analysis. LAB prevailed in all cheeses followed by yeasts. Enterobacteria, pseudomonads, and staphylococci were present as <100 viable cells/g of cheese. The yogurt starters Streptococcus thermophilus and Lactobacillus delbrueckii were the most abundant LAB isolates, followed by nonstarter strains of Lactiplantibacillus, Lacticaseibacillus, Enterococcus faecium, E. faecalis, and Leuconostoc mesenteroides, Citation: Samelis, J.; Doulgeraki, A.I.; whose isolation frequency was batch-dependent.

APPENDIX a Media and Reagents
APPENDIX A Media and Reagents Pauline K. w. Yu, M.S. The use of appropriate and dependable media is integral to the isolation and identification of microorganisms. Unfortunately, comparative data docu menting the relative efficacy or value of media designed for similar purposes are often lacking. Moreover, one cannot presume identity in composition of a given generic product which is manufactured by several companies because each may supplement the generic products with components, often of a proprietary nature and not specified in the product's labeling. Finally, the actual production of similar products may vary among manufacturers to a sufficient extent to affect their performance. For all of these reasons, therefore, product selection for the laboratory should not be strictly based on cost considerations and should certainly not be based on promotional materials. Evaluations that have been published in the scientific literature should be consulted when available. Alternatively, the prospective buyer should consult a recognized authority in the field. It is seldom necessary for the laboratory to prepare media using basic components since these are usually available combined in dehydrated form from commercial sources; however, knowledge of a medium's basic compo nents is helpful in understanding how the medium works and what might be wrong when it does not work. Hence, the components have been listed for each medium included in this chapter. All dehydrated media must be prepared exactly according to the manu facturers' directions. Any deviation from these directions may adversely affect or significantly alter a medium's performance. Containers of media should be dated on receipt and when opened, and the media should never be used beyond expiration dates specified by the manufacturers or recom mended by quality control programs. -

Microbial density determined using plate count agar (total aerobic bacteria), de Man Rogosa Sharpe agar (Lactobacillus), M17 agar (Lactococcus) and yeast peptone dextrose agar supplemented with streptomycin 50 ppm (yeast). Nutritional content and acidity level of each fermented milk sample were also evaluated. Genomic DNA was extracted using FastDNA Spin (MPBIO). The total gDNA was further analyzed using illumina high-throughput se- quencing (paired-end reads), and the sequence results were analysed using QIIME v.1.9.1 to generate diversity profiles. The difference in nutrient content of mare’s milk was thought to affect the density and diversity of microbes that were able to grow. Fermented mare’s milk samples from Sum- bawa had the highest bacterial diversity compared to samples from Bima and Dompu. However, fermented mare’s milk from Dompu had the best quality which was indicated by the absence of bacteria that have the potential to be pathogenic or food spoilage, such as members of the Enterobacte- riaceae family (Enterobacter, Klebsiella and Escherichia-Shigella) and Pseudomonas. -

These clinical signs result from a systemic inflammatory response to microbes or microbial products present in sterile sites such as blood.

Supplementary Material
Supplementary Material SUPPLEMENTARY METHODS Definition of failure for prior clinical treatments According to the standard operating procedures of our outpatient clinic treatment, failures are defined by Mayo-score as follows: 1. Patients are non-responders to thiopurines after treament with azathioprine 2- 2.5mg/kg/day or 6-mercaptopurine 1-1.5mg/kg/day for at least 3-6 months despite 6-TGN levels > 235 pmol/8x108 red blood cells (RBC). 2. Primary lack of response to anti-TNF agents is determined within the first 12 weeks of therapy. 3. In patients with loss of response to anti-TNF agents, reduction in interval between doses, dose escalation or both (e.g. infliximab: up to 10mg/kg every 4 weeks, adalimumab: up to 40mg every week) is performed. If there is no response after reduction in interval and dose escalation patients are rated as secondary anti-TNF failures. Evaluation of different methods for preparation of faecal suspensions Because protocols for donor stool preparations differ between published faecal transplantation studies, prior to treating patients we assessed the quantitative and qualitative difference in the bacterial content between native stool and three different stool preparations: (A) 30 g of fresh stool were mixed with 450 ml of 0.9% sterile saline solution to an almost homogeneous suspension, (B) the suspension prepared from (A) was filtered several times through an increasing number of gauze pads to remove small particles, (C) the suspension prepared from (A) was centrifuged at 1912xg (3000 rpm) and the supernatant was used for further analysis. Native stool and each of the preparations were plated on five different solid culture media. -

Diversity analysis, identification, and bioprospecting of Lactic Acid Bacteria (LAB) isolated from Sumbawa horse milk. Biodiversitas 22: 3333-3340. Sumbawa horse milk has a probiotic potential because of the presence of Lactic Acid Bacteria (LAB). The LAB present in Sumbawa horse milk has been reported to have antimicrobial activities against pathogenic bacteria, including Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, and Vibrio cholerae. However, the potential of LAB from Sumbawa horse milk as antioxidant and antidiabetic is still unexplored. Studies related to the diversity of indigenous bacteria in Sumbawa horse milk based on metagenomic analysis have not been widely studied either. Therefore, this study aimed to determine the diversity of species of indigenous bacteria in Sumbawa horse milk and to identify LAB bioprospecting from Sumbawa horse milk.
