Comparative Analyses of Select Microbial Growth Inhibited Rate Models
Abstract: Food waste is a complex substrate comprising of different mixtures of chemical compounds. The growth rate of micro-organism in such environment will experience inhibition. Consequently, the Monod’s model will not be able to describe the growth rate of its bacteria. The Aiba’s, Andrews and the Haldane’s growth rate models that are accounts for growth rate of bacteria with inhibition were compared. To do this, seven different batch experimentations; each with …

Long-Term Effects of Feeding High-Lignin Forage to Ruminants: Implications for Productivity, Health, and Sustainability
Abstract: The long-term feeding of high-lignin forage to ruminants can significantly impact various aspects of animal performance, health, and environmental sustainability. Lignin, a complex phenolic compound present in plant cell walls, is indigestible by rumen microbes, leading to reduced fiber digestibility and decreased nutrient utilization. Over time, feeding ruminants with forages high in lignin results in a decline in voluntary dry matter intake (DMI), inefficient energy and protein absorption, and suboptimal …

Understanding Food Spoilage: Mechanisms, Shelf-Life Determination, and Safety Standards
Abstract: Food spoilage poses significant challenges to the global food industry, impacting both food safety and economic sustainability. The main causes of food quality deterioration are microbial and non-microbial spoiling. Microbial spoilage primarily results from the activity of bacteria, yeasts, and molds, which thrive under favorable environmental conditions. These microorganisms can lead to food poisoning and spoilage through the production of off-flavors, discoloration, slime formation, and the accumulation of harmful toxins. …

Microbial Competition in the Rumen: Insights into Fermentation Kinetics, Host Health, and Environmental Sustainability
Abstract: Microbial competition within the rumen is a crucial determinant of fermentation efficiency, nutrient utilization, and overall host health in ruminant animals. The complex microbial community in the rumen comprises bacteria, protozoa, fungi, and archaea, all of which interact in intricate and often competitive ways to degrade feed and produce essential metabolites. This competition significantly influences fermentation kinetics, determining the rate and efficiency of carbohydrate, protein, and fat breakdown. Such microbial …

Persistent Atmospheric and Ecosystem Impacts of Enteric Methane Emissions from Intensive Livestock Production Systems
Abstract: Enteric methane emissions from intensive livestock production systems exert a significant long-lasting influence on atmospheric stability and ecosystem integrity. Recent observations confirm that global methane emissions continued to rise through the early 2020s, with total emissions exceeding 620 teragrams per year by 2024, driven by expanding ruminant production and associated feed systems. Anthropogenic sources accounted for more than 330 teragrams per year, reflecting sustained growth in agricultural and fossil fuel …
