Kombucha is a functional beverage produced through the fermentation of infused tea or Camelia sinensis (L.) Kuntze (CS) by a symbiotic culture of bacteria and yeast. Apparently, the substrate of kombucha can be substituted to enhance its functional properties. Ganoderma lucidum (GL) is a potential substrate reported to have health benefits. This study aims to evaluate antioxidant properties by comparing different formulations and fermentation times. The formulations prepared in the present study varied in the compositions of GL and CS substrates, namely F1 (100% GL), F2 (75% GL: 25% CS), F3 (50% GL: 50% CS), F4 (25% GL: 75% CS), …

Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Identification Of A Small Regulatory Rna Usps Associated With The Universal Stress Protein In Lactobacillus Species, Zarah M. Fowler, Sasha S. Bronovitskiy, Finn K. Rose, Brian M. Lee

Journal of the South Carolina Academy of Science

The gut microbiome is a complex habitat with many bacterial species, each playing crucial roles in regulating various physiological processes in the body. As the use of probiotics to combat human disease continues to increase, it is important to understand the mechanisms by which probiotic bacteria regulate their interactions with other bacteria and their host. Our exploration of the physiological functions of probiotic bacteria hopes to elucidate the role of small regulatory RNA (sRNA) in regulating gene expression within the microbiome. The goal of this project was to characterize the structure and function of the sRNA, UspS, which is found …

Potential Use Of Proteolytic Bacteria Paenibacillus Dendritiformis (Bt7) Isolated From Batu Tannery Effluents For The Detergent Industry, Chandran Masi, Degafneh Tadesse, Abate Ayele

Karbala International Journal of Modern Science

This research was aimed at identifying a bacterium that can produce alkaline proteases. As a result, bacteria that produce proteases were isolated from Batu tannery effluents, tested for protease synthesis on skim milk agar plates, and validated with a protease assay. Microscopic and molecular phylogenetic analyses identified Paenibacillus dendritiformis (BT7) as the bacterial isolate with the highest alkaline protease production. The isolate's maximum enzyme production was obtained by 2% inoculum size, 40°C temperature, 9.0 pH, and a 48-hour incubation time with production media components such as glucose, casein, MgCl2, and 2% NaCl. The maximal enzyme activity was 270 U/mL under …

Amelioration Of Cr (Vi) Into Cr (Iii) By Some Heavy Metal Resistant Bacterial Strains Isolated From Naran Valley, Ifrah Fayyaz, Asma Kalsoom, Rida Batool

Journal of Bioresource Management

Total thirty-two strains were isolated from both water and soil samples collected from Naran Valley which is surrounded by the rugged mountains, located in the province of Khyber Pakhtunkhwa, Pakistan. Streak plate method was used to screen the bacterial strains for resistance against selected heavy metals like chromium (Cr), cobalt (Co), copper (Cu), nickel (Ni) and zinc (Zn). Resistance against multiple heavy metals was shown by all the strains, but S15 and W15 were significant as they exhibited a maximum resistance to chromium and copper (1200 µg/ml). These strains also presented multiple antibiotic (ampicillin, tetracycline, chloramphenicol, and erythromycin) resistance patterns. …

A Nosy Neighbor: Purification And Functional Characterization Of Lpg2149, Ashley M. Holahan

The Journal of Purdue Undergraduate Research

Ubiquitination is a process that marks proteins for various cell-signaling pathways, namely protein degradation and other processes. Th ese pathways are essential in a wide array of cellular processes, including defense mechanisms against invading pathogens. Th e ubiquitination process is universally found in all eukaryotic organisms, including plants and animals, and thus plays a vital role in cellular homeostasis. Recently, more discoveries have been made on prokaryotic effector proteins that hijack the ubiquitination system even when they do not possess a ubiquitin system of their own. MavC, also known as lpg2147 (Gan, Nakayasu, Hollenbeck, & Luo, 2019; Puvar et al., …

Overcoming Obstacles In Protein Expression In The Yeast Pichia Pastoris: Interviews Of Leaders In The Pichia Field, Zoe Ingram, Abha Patkar, Dahoon Oh, Kevin K. Zhang, Christina Chung, Joan Lin-Cereghino, Geoff P. Lin-Cereghino

Pacific Journal of Health

The yeast Pichia pastoris (also known as Komagataella pastoris) has been used for over 30 years to produce thousands of valuable, heterologous proteins, such as insulin to treat diabetes and antibodies to prevent migraine headaches. Despite its success, there are some common, stubborn problems encountered by research scientists when they try to use the yeast to produce their recombinant proteins. In order to provide those working in this field with strategies to overcome these common obstacles, nine experts in P. pastoris protein expression field were interviewed to create a written review and video (https://www.youtube.com/watch?v=FyC9xXVLyD0). This review describes …

The Effects Of Inulin And Galactooligosaccharides On The Production Of Reuterin By Lactobacillus Reuteri, Micah Dwight Forshee

ELAIA

The microbiome is a dynamic community that can positively and negatively influence host health. Lactobacillus reuteri is a probiotic that has received much attention for its ability to inhibit pathogens such as Salmonella typhimurium, Escherichia coli, and Clostridium difficile. It does so by its unique ability to metabolize glycerol into the antimicrobial compound 3-HPA, which is commonly referred to as reuterin. The ability to secrete reuterin is dependent not only on glycerol availability but also the concentration of glucose. In fact, there appears to be a “goldilocks” ratio between glucose and glycerol as either too much or too little …

Malnutrition In Sickle Cell Anemia: Implications For Infection, Growth And Maturation, Hyacinth I. Hyacinth, Oluwatoyosi A. Adekeye, Christopher S. Yilgwan

Journal of Social, Behavioral, and Health Sciences

Sickle cell anemia (SCA) is a genetic disease that affects mostly individuals of African and/or Hispanic descent, with the majority of cases in sub-Saharan Africa. Individuals with this disease show slowed growth, delayed sexual maturity, and poor immunologic function. These complications could partly be explained by the state of undernutrition associated with the disease. Proposed mechanism of undernutrition include protein hypermetabolism, decreased dietary intake possibly from interleukin-6-related appetite suppression, increased cardiac energy demand/expenditure, and increased red cell turnover. All the above mechanisms manifest as increased resting energy expenditure. Nutritional intervention utilizing single or multiple nutrient supplementation has led to improved …
