Anaerobic Digesters: Methane Formation

Anaerobic Digesters: Methane Formation. The inter-microbial distances influence the biodegradation rates and specific growth in the formation of Methane. The microorganisms that form methane are physiological. They can grow only with a few specific substrates, such as H2 and CO2, formate, methanol, and acetate, and they, therefore, depend on others. Therefore, a syntrophic relationship is…

Sustainable Livestock Production

As any rancher in today’s world knows, sustainable livestock production is the ticket to the best markets. Large buyer companies are demanding sustainable livestock production supporting the food at the store, because today’s consumers are demanding it from them.  A few examples of sustainable livestock production would be recycling products on the ranch, maintaining native…

Biochemical Conversion Processes

Biochemical conversion processes? Enzymes and micro-organisms are frequently used as biocatalysts to convert biomass or biomass-derived compounds into desirable products. Biotechnology advances are expected to lead to dramatic biochemical conversion improvements. The most popular biochemical technologies are anaerobic digestion (or biomethanation) and fermentation. Cellulase and hemicellulase enzymes break down the carbohydrate fractions of biomass into…

Feed Ingredient Evaluation for Livestock Producers

Livestock feed evaluation? Livestock producers are constantly in search of ways to improve the economics of their operations.  One effective way of realizing improved economics is to incorporate new ingredients into the feeding operation.  In this venture, producers must be careful to make certain they are familiar with the new ingredient and fully aware of…

Biofuels Co-Products: Animal Feed

A significant portion of biofuels co-products is in the area of animal feed – often livestock feeding.  Does this naturally raise the question as to whether there is a difference between animal-grade and human-grade food ingredients?  From a strict, regulatory standpoint, the rules promulgated by the FDA are similar but different.  Human food rules are…

Biofuels and Livestock Production

Livestock production and biofuels – especially ethanol – seem like a match made in Heaven.  Ethanol producers can leverage the corn-purchase requirements of integrated operations for the economic benefit of both.  Also, the co-products coming out of the ethanol plant can be fed back to the livestock – with the cost-savings synergies realized in not…

Anaerobic Digesters: Methanogen

Methanogen refers to an anaerobic process in which the electron equivalents in organic matter (BODL) are used to reduce carbon to its most reduced oxidation state, -4 in CH4, or methane. Methane is a poorly soluble gas that evolves from water. Thus, the BODL is removed from the water by directing electron equivalents to CH4,…

Process Development: Bench to Commercialization

Process development -leading a process from bench-scale optimization and characterization through scale-up to piloting and commercialization requires a variety of knowledge and skills for the process development engineer and scientist.  Beyond core competencies (e.g. chemistry, thermodynamics, mass and energy balances, etc.) of those that work in process development teams, there are additional skills that help…
