For decades, Alzheimer's disease (AD) research has been dominated by the amyloid cascade hypothesis, focusing on the accumulation of amyloid plaques in the brain. However, recent studies have brought to light a new paradigm that could reshape our understanding of this devastating condition. More recent research utilizing advanced sequencing technology has revealed compelling evidence of a bacterial component in the development of Alzheimer's disease. A new study published this week also suggests a connection between AD and a pathogenic microbiome in the brain, which may result from a compromised blood-brain barrier (BBB) .  The study analyzed postmortem brain samples from 32 individuals, comprising 16 AD patients and 16 age-matched control subjects. A total of 130 samples were collected from various brain regions. Researchers employed full-length 16S rRNA gene amplification with Pacific Biosciences sequencing technology to identify bacteria within these samples. Notably, they ...

Livestock and poultry breeding generate substantial amounts of waste, contributing to environmental challenges. Odorous gases, including ammonia, hydrogen sulfide, and volatile organic compounds (VOCs), are common byproducts of composting livestock waste. The Biological Trickling Filter (BTF) is a cutting-edge biological air treatment system that combines equipment, media, and the NUCIRC process to deliver outstanding performance and adaptability. It operates as a hybrid of a biofilter and bioscrubber, where essential bacteria responsible for decomposition are immobilized on a carrier or filter material. This article delves into the key components of the BTF and its role in mitigating odorous gases produced during livestock and poultry breeding. Additionally, it explores the innovative use of synthetic microbial consortia to optimize odor treatment within the BTF. Aerobic composting relies on the activity of various microorganisms, including bacteria, actinomycetes, and fungi. The comp...

Mikania plants, particularly Mikania glomerata and Mikania laevigata, have been the subject of various scientific studies and patents due to their significant antibacterial activities. These vines, native to Southeastern Brazil, are not just a part of traditional medicine but are also making strides in modern scientific research. Mikania plants have been the subject of patent filings for over two decades. A Japanese inventor published a patent about odor-suppressing Mikania plants twenty years ago (Ishimaru, 2003). More recently, another patent was filed and granted . Stanley Hazen's team secured this patent for a method involving Mikania extract to inhibit the conversion of choline to trimethylamine (TMA). According to a recent systematic review , Mikania glomerata is among the plant species with the best overall mean MIC (Minimum Inhibitory Concentration) values, ranging from 3.5–16 μg/mL. The review also highlighted that of the 76 species from the Asteraceae family with antibac...

uBiome, once a prominent player in the microbiome testing market, encountered challenges and controversies that culminated in bankruptcy. However, the void left by uBiome has been filled by many new companies offering microbiome home tests. These tests, ranging in cost from $50 to almost $1,000, are provided by companies including ZOE, Floré, Ombre, Thorne, Verisana, and Wellnicity. Their primary appeal lies in their convenience, allowing individuals to collect their stool samples discreetly, ship them, and receive personalized reports within weeks. It's essential to note that the Food and Drug Administration (FDA) does not approve these home test kits, and they should not replace professional medical diagnosis or consultation with healthcare providers. Among these companies, Viome emphasizes personalized nutrition recommendations based on microbiome analysis, taking a holistic approach to health and wellness. ZOE offers advanced analysis of gut bacteria, blood sugar, and blood fat...

As the dawn of genetic engineering has started breaking barriers across multiple sectors, there are microscopic but potent entities that could be at the epicenter of many innovations - microbes that live all around us and sometimes call us home. The human microbiome, comprising trillions of microorganisms, plays a vital role in maintaining overall health. Genetically engineered probiotics have the potential to positively influence the composition and function of the microbiome. With the successful advent of genetically engineered bacteria, the fields of probiotics and personal care products could be significantly impacted, leading to a series of groundbreaking innovations.  Genetically engineered (GE) microorganisms have their genetic material altered through genetic engineering techniques. This equips them with new properties, enabling to produce useful substances, counteract certain processes or perform specific functions. This includes everything from producing insulin to treati...

Mobiluncus (causing vaginal odor) and Peptoniphilus (causing underarm odor) may also contribute to body odor if present in the navel. Read more at our Olfactics blog.
