Understanding the Role of pH Regulation and Neutralizing Agents in Organic Acid Production and Growth of Aspergillus oryzae

Biotechnology and Bioengineering, EarlyView.
We show that pH and neutralization strategy strongly influence the growth, pellet morphology, and organic acid production of Aspergillus oryzae. Acidic and alkaline conditions lead to hairy, dispersed pellets, while near‐neutral environments favour compact pellet formation.

The Role of the Glyoxylate Shunt in the Acclimation to Iron Limitation in Marine Heterotrophic Bacteria

Frontiers in Marine Science, 2018
Iron (Fe) is an essential element for marine microbial growth but is present in trace amounts (<0.1 nM) in surface waters of the ocean. In heterotrophic bacteria, Fe-limitation particularly impacts ATP production as Fe is an essential co-factor of ...

Cyclization of Citronellal to Isopulegol Catalyzed by Temperature‐Stable Aluminum Complexes with Tripodal Tris(silanolate) Ligands

ChemistryEurope, EarlyView.
C3‐Symmetric aluminum chelate complexes endowed with tripodal tris‐silanolate ligands are shown to be excellent catalysts for the selective carbonyl ene‐type cyclization of citronellal to isopulegol as the key intermediate of the current industrial syntheses of menthol.

Biological Conversion of Formate to Organic Compounds: Toward a Sustainable Formate Bioeconomy

Carbon Energy, EarlyView.
Formate bioconversion plays a crucial role in achieving renewable resource utilization and sustainable development. To tap its full potential, it is important to identify the most appropriate microbial hosts for incorporating formate into building blocks, design the most promising metabolic pathways for transmitting formate into central carbon ...

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Cellular responses of Candida albicans to phagocytosis and the extracellular activities of neutrophils are critical to counteract carbohydrate starvation, oxidative and nitrosative stress.

PLoS ONE, 2012
Neutrophils are key players during Candida albicans infection. However, the relative contributions of neutrophil activities to fungal clearance and the relative importance of the fungal responses that counteract these activities remain unclear.

Gene expression profiling of protease and non-protease genes in Trichophyton mentagrophytes isolates from dermatophytosis patients by qRT-PCR analysis

Scientific Reports, 2021
Trichophyton mentagrophytes secretes Metallocarboxypeptidase A and B of the M14 family as endoproteases and exoprotease. T. mentagrophytes produce Metalloprotease 3 and 4 which degrades the protein into the short peptides and amino acids.

Trash‐to‐Energy: Shedding Light on Plastic and Biomass Valorization Through Artificial Photosynthesis Towards Sustainability

Exploration, EarlyView.
To engrave a circular economy, artificial photosynthesis emerges as a promising and prosperous strategy to upcycle solid waste into clean fuel and valuable chemicals for sustainable fuel production. This review highlights the design of photocatalysts and external‐field‐assisted photocatalysis for effective solid waste conversion toward an ...

The Nutritional Composition and Multi‐Omics Analysis of Raw Milk From Normande and Holstein Cows

Food Frontiers, EarlyView.
Normande milk is characterized by high protein and fat content, whereas Holstein milk is distinguished by its high milk yield. However, few studies have reported on their compositional differences. Thus, we used physicochemical and multi‐omics techniques to investigate the compositional differences between Normande and Holstein raw milks. ABSTRACT Milk

A novel role of the PrpR as a transcription factor involved in the regulation of methylcitrate pathway in Mycobacterium tuberculosis. [PDF]

PLoS ONE, 2012
Mycobacterium tuberculosis, the pathogen that causes tuberculosis, presumably utilizes fatty acids as a major carbon source during infection within the host.
