Effects of preservation method on canine (Canis lupus familiaris) fecal microbiota. [PDF]

, 2018
Studies involving gut microbiome analysis play an increasing role in the evaluation of health and disease in humans and animals alike. Fecal sampling methods for DNA preservation in laboratory, clinical, and field settings can greatly influence ...

Advances in Plant-Nematode Interactions with Emphasis on the Notorious Nematode Genus Meloidogyne. [PDF]

, 2019
Plant infections by plant-parasitic nematodes (PPNs) continue to be one of the major limitations in agricultural systems. Root-knot nematodes (RKNs), belonging to the genus Meloidogyne, are one of the most important groups of PPNs worldwide.

Substrate-specific clades of active marine methylotrophs associated with a phytoplankton bloom in a temperate coastal environment [PDF]

, 2008
Marine microorganisms that consume one-carbon (C1) compounds are poorly described, despite their impact on global climate via an influence on aquatic and atmospheric chemistry.

Gut Microbial Metabolism and Nonalcoholic Fatty Liver Disease. [PDF]

, 2019
The gut microbiome, the multispecies community of microbes that exists in the gastrointestinal tract, encodes several orders of magnitude more functional genes than the human genome. It also plays a pivotal role in human health, in part due to metabolism

Genetic basis of microbial carotenogenesis

International Microbiology, 2003
The synthesis of carotenoids begins with the formation of a phytoene from geranylgeranyl pyrophosphate, a well conserved step in all carotenogenic organisms and catalyzed by a phytoene synthase, an enzyme encoded by the crtB ( spy) genes. The next step is the dehydrogenation of the phytoene, which is carried out by phytoene dehydrogenase.

Competition between homologous chromosomal DNA and exogenous donor DNA to repair CRISPR/Cas9-induced double-strand breaks in Aspergillus  niger

Fungal Biology and Biotechnology
Background Aspergillus niger is well-known for its high protein secretion capacity and therefore an important cell factory for homologous and heterologous protein production.

cual-id: Globally Unique, Correctable, and Human-Friendly Sample Identifiers for Comparative Omics Studies

mSystems, 2016
The number of samples in high-throughput comparative “omics” studies is increasing rapidly due to declining experimental costs. To keep sample data and metadata manageable and to ensure the integrity of scientific results as the scale of these projects ...

Elevated acetate kinase (ackA) gene expression, activity, and biofilm formation observed in methicillin-resistant strains of Staphylococcus aureus (MRSA)

Journal of Genetic Engineering and Biotechnology, 2023
Background Staphylococcus aureus spreads its infections through biofilms. This usually happens in the stationary phase of S. aureus growth where it utilizes accumulated acetate as a carbon source via the phosphotrans-acetylase-acetate kinase (Pta-Ack ...

Salmonella stress response systems as targets for anti-virulence strategies

BMC Microbiology
Due to the rapid development of antibiotic resistance, novel strategies to cope with bacterial infections are urgently required. Ideally, these strategies should exert less selection pressure for resistance than traditional antibiotics.
