Single Cell Protein Production From Ethanol: Model‐Based Bioreactor Operation at Industrial Scale

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Alternative fermentation feedstocks such as ethanol can be produced from CO2 via electrocatalytic processes that coproduce O2. In this study, industrial‐scale fermentation of ethanol with pure O2 for single cell protein (SCP) production was studied using a modeling approach.

Impact of Salmonella genome rearrangement on gene expression

open access: yesEvolution Letters, Volume 6, Issue 6, Page 426-437, December 2022., 2022
Abstract In addition to nucleotide variation, many bacteria also undergo changes at a much larger scale via rearrangement of their genome structure (GS) around long repeat sequences. These rearrangements result in genome fragments shifting position and/or orientation in the genome without necessarily affecting the underlying nucleotide sequence.

The pivotal role of mass spectrometry in transition metal‐based photocatalyst research for solar‐driven energy conversion and water purification advancements

open access: yesBulletin of the Korean Chemical Society, EarlyView.
This review explores recent advancements in the integration of solar energy conversion and water remediation with mass spectrometry as an analytical technique. We examine Ti‐based photocatalysts for their roles in energy conversion and water purification, utilizing mass spectrometric analysis to evaluate the efficiency of these mechanisms.

Genomics and marine microbial ecology [PDF]

open access: yes, 2010
Genomics has brought about a revolution in all fields of biology. Before the development of microbial ecology in the 1970s, microbes were not even considered in marine ecological studies.

Impact of land conservation status on soil functionality in degraded versus old‐growth forest in the Brazilian Atlantic Forest biome

open access: yesBiological Diversity, EarlyView.
Preserved forests of Ocotea porosa exhibited improved soil functionality with higher levels of soil organic matter (6.56%), exchangeable cations (e.g., Ca2+ at 3.87 cmolc kg−1), and enhanced physical properties, such as soil aggregation, than degraded forests in the Atlantic Forest biome.

Characterization of biodegradable food packaging films prepared with polyamide 4: Influence of molecular weight and environmental humidity

open access: yesFood Bioengineering, Volume 1, Issue 3-4, Page 276-288, December 2022., 2022
Colorless and translucent polyamide 4 (PA4) films, which are both bio‐based and biodegradable, were prepared by the solution casting method in a dual‐solvent system. The physical properties of single PA4 films were originally characterized, and the effects of molecular weight and environmental humidity on PA4 were investigated. Abstract The development
