An evaluation of Saudi Arabia’s policies for economic diversification [PDF]

, 1984
The aim of this thesis is to evaluate Saudi Arabia's policies for diversification. Economic diversification only became a realistic possibility following the first major oil price rise in the early 1970's.

Volumetric mass transfer and dilution rate as key parameters for sustainable industrial syngas fermentation to isopropyl alcohol: modeling and parametric assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Synthesis gas fermentation is a promising route for the valorization of steel mill off‐gas and for replacing conventional fossil‐based isopropyl alcohol (IPA) production. A recent 120 L pilot‐scale study reported 85% gas conversion at 90% product selectivity and claimed a negative global warming potential (GWP) without detailed process design.

Process development priorities for scaling up direct microbial conversion of sugars into value‐added biochemicals

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The study identified process development priorities toward the feasible production of five value‐added biochemicals in a sugarcane biorefinery based on achievable bioconversion performances. Multiple process scenarios using A‐molasses as feedstock were simulated in Aspen Plus® via direct microbial conversions.

Market potential of biobased chemicals: a qualitative network analysis of adoption dynamics in South Africa’s bioeconomy

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The premise of a bioeconomy is the replacement of nonrenewable and unsustainable fossil‐derived resources and associated technologies with more sustainable alternatives. The adoption of biobased chemicals contributes toward the growth of a bioeconomy and is dependent on market and industry requirements.

Influence of Zn2+ and Oxygen Supply on Malic Acid Production and Growth of Aspergillus oryzae

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Malic acid is a valuable platform chemical traditionally derived from fossil‐based resources. Microbial cultivation with Aspergillus oryzae offers a sustainable alternative based on renewable feedstocks. In this study, a well‐established minimal medium for malic acid production, commonly used in previous research to ensure reproducibility, was
