Enabling Cl-Based bioconversion with metabolic engineering
Single-carbon (C) substrates, such as synthesis gas and methanol, are attractive feedstocks for biochemical processes, as they are widely available, can be produced renewably, and do not compete with food supply. However, their use in industrial bioprocessing remains limited, primarily because …

Bioconversion of lignocellulosic hydrolysate to acetic acid using Moorella thermoacetica
A systematic study of bioconversion of lignocellulosic sugars to acetic acid by Moorella thermoacetica strain ATCC 39073 was conducted. Four different hydrolysates obtained after steam pretreatment of lignocellulosic biomass were selected and fermented to acetic acid in batch fermentations. The …

The application of ultrasound in the bioconversion of brewer’s and distiller’s spent grains to bioethanol
In recent years bioethanol (fuel ethanol derived through fermentation) has become the leading alternative to currently utilised liquid transportation fuels, possessing the benefits of being both sustainable and carbon neutral. If this position is to be maintained, it is clear that the feedstocks …

An investigation into the bioconversion of South African sub-bituminous coal by Trametes species and Trichoderma atroviride
… describes the preliminary investigation of the bioconversion of a South African (SA) sub-bituminous coal to produce low molecular mass intermediates which may be used in further processes to yield value-added compounds. Low rank coals (LRC), which are less desirable for combustion processes than …

Enhanced β-galctosidase activity in probiotics for improved bioconversion of soy isoflavones in dairy and soy-based yoghurt
The main aims of this project were to evaluate the suitability of whey as a medium for the production of β- galactosidase (β-gal) from Lactobacillus delbrueckii ssp. bulgaricus ATCC 11842 (LB) and Bifidobacterium animalis Bb12 (BB12). The study was undertaken to examine and compare the influence of …

Impact of Dietary Composition and Beta-Carotene Isomeric Structure on Bioconversion of Beta-Carotene to Vitamin a in Gerbils
In conclusion, betaC bioconversion to VA was independently and adversely affected by consumption of low dietary fat and citrus pectin. 9-Cis betaC was less and 13cbetaC was more than the currently assigned retinol equivalency of 50% of atbetaC. Thus, the actual contribution of betaC to the VA …

Evaluation of the Economic, Social, and Biological Feasibility of Bioconverting Food Wastes with the Black Soldier Fly (Hermetia illucens)
… animals capable of consuming the food wastes. Bioconversion, a potential alternative, is a waste management practice that converts food waste to insect larval biomass and organic residue. This project uses a native and common non-pest insect in Texas, the black soldier fly, which processes …
