Evaluation of Prebiotic and Antimicrobial Properties of Natural Extracts

Prebiotics are compounds in food that induce growth or activity of beneficial microorganisms & are beneficial for host health. The most common example is in the gastrointestinal tract, where prebiotics alter composition of organisms in the gut microbiome. Prebiotics are the non-digestible fibers or carbohydrates that gut bacteria can digest, and prebiotics adds nutritional value & help healthy bacteria grow. Prebiotics are associated with Probiotic, microbes which keep intestine healthy and enhance immune system by fighting with harmful bacteria. This study centers on evaluation of prebiotic properties for natural, aqueous extracts of Aloe vera (Aloe barbadensis miller), Kokum dried (Garcinia indica), and Wheatgrass (Triticum aestivum) by stimulation of growth, of probiotic organism Lactobacillus casei isolated on Sterile Man Rogosa Sharpe Agar and was measured colorimetrically at 545 nm. Antimicrobial and biopreservative study were also performed of these extracts. Hence to evaluate the variable properties of being used in cancer treatment, cosmetics, food industry, etc. Presence of Vitamin C in these plants by DCPIP method broadens the idea of Prebiotics applications, like better immune health and wound healing. Probiotic organism is also used in horticulture, in this study it resulted in enhancing the process of germination, Lactobacillus casei of 108cfu/ml was incorporated in soil to enhance germination of fenugreek seed and kokum extract as a prebiotic source. Additionally, an online survey with Questionnaire methodology was conducted on Awareness and usage about prebiotic and probiotics by online platform and results were analyzed by graphical and statistical method.

The Effect of Feed Supplementation with EM Bokashi® Multimicrobial Probiotic Preparation on Selected Parameters of Sow Colostrum and Milk as Indicators of the Specific and Nonspecific Immune Response

The aim of the study was to determine the effect of EM Bokashi® on selected parameters of the specific and nonspecific immune response of sows by in colostrum and milk samples. The percentage of cells with expression of CD19+, CD5+CD19+, CD21+, SWC3a (macrophage/monocyte), and CD11b+ molecules on the monocytes and granulocytes as well as the concentrations of lysozyme and acute phase proteins — serum amyloid-A (SAA) and haptoglobin (Hp) were evaluated. The study was carried out on a commercial pig farm, including 150 sows (Polish Large White × Polish Landrace) at the age of 2–4 years. Sixty female sows were divided into two groups: I — control and II — experimental. For the experimental group, a probiotic in the form of the preparation EM Bokashi® in the amount of 10 kg/tonne of feed was added to the basal feed from mating to weaning. The material for the study consisted of colostrum and milk. The samples were collected from all sows at 0, 24, 48, 72, 96, 120, 144, and 168 h after parturition. The study showed that exposure of the pregnant sow to the probiotic microbes contained in EM Bokashi® significantly affects the immunological quality of the colostrum and milk and caused an increase in the percentage of the subpopulations of B cells with CD19+, CD21+, and CD5+CD19+ expression in the colostrum and milk, which demonstrates an increase in the protective potential of colostrum and indicates stimulation of humoral immune mechanisms that protect the sow and the piglets against infections.

Procoagulant and Antimicrobial Effects of Chitosan in Wound Healing

Chitosan, a polysaccharide derived from chitin, has excellent wound healing properties, including intrinsic antimicrobial and hemostatic activities. This study investigated the effectiveness of chitosan dressing and compared it with that of regular gauze dressing in controlling clinically surgical bleeding wounds and profiled the community structure of the microbiota affected by these treatments. The dressings were evaluated based on biocompatibility, blood coagulation factors in rat, as well as antimicrobial and procoagulant activities, and the microbial phylogenetic profile in patients with abdominal surgical wounds. The chitosan dressing exhibited a uniformly fibrous morphology with a large surface area and good biocompatibility. Compared to regular gauze dressing, the chitosan dressing accelerated platelet aggregation, indicated by the lower ratio of prothrombin time and activated partial thromboplastin time, and had outstanding blood absorption ability. Adenosine triphosphate assay results revealed that the chitosan dressing inhibited bacterial growth up to 8 d post-surgery. Moreover, 16S rRNA-based sequencing revealed that the chitosan dressing effectively protected the wound from microbial infection and promoted the growth of probiotic microbes, thereby improving skin immunity and promoting wound healing. Our findings suggest that chitosan dressing is an effective antimicrobial and procoagulant and promotes wound repair by providing a suitable environment for beneficial microbiota.

On pickles: biological and sociocultural links between fermented foods and the human gut microbiome

Background The composition of the human microbiome varies considerably in diversity and density across communities as a function of the foods we eat and the places we live. While all foods contain microbes, humans directly shape this microbial ecology through fermentation. Fermented foods are produced from microbial reactions that depend on local environmental conditions, fermentation practices, and the manner in which foods are prepared and consumed. These interactions are of special interest to ethnobiologists because they link investigations of how people shape and know the world around them to local knowledge, food traditions, local flora, and microbial taxa. Methods In this manuscript, we report on data collected at a fermentation revivalist workshop in Tennessee. To ask how fermentation traditions are learned and influence macro and micro ecologies, we conducted interviews with eleven people and participated in a four-day craft fermentation workshop. We also collected 46 fermented food products and 46 stool samples from workshop participants eating those fermented foods. Results We identified ten major themes comprised of 29 sub-themes drawn from 326 marked codes in the transcripts. In combination, this analysis allowed us to summarize key experiences with fermentation, particularly those related to a sense of authenticity, place, health, and the discovery of tactile work. From the 605 amplicon sequence variants (ASVs) shared between food and fecal samples, we identified 25 candidate ASVs that are suspected to have been transmitted from fermented food samples to the gut microbiomes of the workshop participants. Our results indicate that many of the foods prepared and consumed during the workshop were rich sources of probiotic microbes. Conclusions By combining these qualitative social and quantitative microbiological data, we suggest that variation in culturally informed fermentation practices introduces variation in bacterial flora even among very similar foods, and that these food products can influence gut microbial ecology.

Purification of Crude Fructo-Oligosaccharide Preparations Using Probiotic Bacteria for the Selective Fermentation of Monosaccharide Byproducts

Probiotics are microbes that promote health when consumed in sufficient amounts. They are present in many fermented foods or can be provided directly as supplements. Probiotics utilize non-digestible prebiotic oligosaccharides for growth in the intestinal tract, contributing to a healthy microbiome. The oligosaccharides favored by probiotics are species-dependent, as shown by the selective utilization of substrates in mixed sugar solutions such as crude fructo-oligosaccharides (FOS). Enzymatically produced crude FOS preparations contain abundant monosaccharide byproducts, residual sucrose, and FOS varying in chain length. Here we investigated the metabolic profiles of four probiotic bacteria during the batch fermentation of crude FOS under controlled conditions. We found that Bacillus subtilis rapidly utilized most of the monosaccharides but little sucrose or FOS. We therefore tested the feasibility of a microbial fed-batch fermentation process for the purification of FOS from crude preparations, which increased the purity of FOS from 59.2 to 82.5% with a final concentration of 140 g·l−1. We also tested cell immobilization in alginate beads as a means to remove monosaccharides from crude FOS. This encapsulation concept establishes the basis for new synbiotic formulations that combine probiotic microbes and prebiotic oligosaccharides.

Global impact and clinical management of severe respiratory syndrome coronovirus-2 (COVID-19)

Coronaviruses are enveloped non-segmented positive-sense RNA viruses belonging to the family Coronaviridae and the order Nidovirales and broadly distributed in humans and other mammals. The recommendations for the management of COVID-19 are mentioned in a lot of Updated Literature such as in The "L. Spallanzani" National Institute for the Infectious Diseases. These recommendations are considered as expert's opinions, which may be modified according to newly produced literature data. In addition, Chloroquine and its derivative, hydroxychloroquine, have a long history as safe and inexpensive drugs for use in malaria-endemic regions and as daily treatments for autoimmune diseases, with the most common side effect being eye damage after long-term use (Kapoor and Kapoor 2020). Although previous studies have revealed that chloroquine has therapeutic activity against viruses, including human corona virus OC43 in animal models and SARS-CoV in cell culture studies. we proposed that from natural Medicine the polyphenol compounds in olive leaf extracts were responsible for the stimulation of probiotic Microbes growth and metabolism and that olive leaf extracts ingested in human diet might have the same effect on desirable components of the intestinal microflora, Herbal medicines, plant products, and phototherapeutic have been widely used all over the world since ancient times. Such as Orange, garlic, Bananas, and lemon have an effect on increasing the immune system. On the other hand; Gold nanoparticles (AuNPs) are a piece of evidence to treat the harmful responses arising from reactive oxygen species (ROS). Silver nanoparticles (AgNPs) are microbial agents which could be potentially used as an alternative to anti-viral to treat human infectious disease, especially influenza; there is a novel treatment by using magnetite nanoparticles as nanomedicine drug for Covid- 19.
