Synergistic Coassembly of Folic Acid-Based Supramolecular Polymer with a Covalent Polymer Toward Fabricating Functional Antibacterial Biomaterials.

Supramolecular biomaterials can recapitulate the structural and functional facets of the native extracellular matrix and react to biochemical cues, leveraging the unique attributes of noncovalent interactions, including reversibility and tunability. However, the low mechanical properties of supramolecular biomaterials can restrict their utilization in specific applications. Combining the advantages of supramolecular polymers with covalent polymers can lead to the fabrication of tailor-made biomaterials with enhanced mechanical properties/degradability.

A repertoire of nanoengineered short peptide-based hydrogels and their applications in biotechnology.

Peptide nanotechnology has currently bridged the gap between materials and biological worlds. Bioinspired self-assembly of short-peptide building blocks helps take the leap from molecules to materials by taking inspiration from nature. Owing to their intrinsic biocompatibility, high water content, and extracellular matrix mimicking fibrous morphology, hydrogels engineered from the self-assembly of short peptides exemplify the actualization of peptide nanotechnology into biomedical products.

Phylogenomic analysis of the genus : proposal for division of this genus into the emended genus and two novel genera gen. nov. and gen. nov.

The members of the genus are key players in the removal of petroleum hydrocarbons from polluted marine environments. More than half of the species were described in the last decade using 16S rRNA gene phylogeny and genomic-based metrics. However, the 16S rRNA gene identity (<94 %) between some members of the genus suggested their imprecise taxonomic status.

Neoroseomonas marina sp. nov., Isolated from a Beach Sand.

A pink-pigmented bacterium (strain JC162 = KCTC 32190) was isolated from a beach sand sample. Cells were Gram-stain-negative, coccoid, non-motile, and strictly aerobic. EzBioCloud BLAST search of 16S rRNA gene sequence showed that strain KCTC 32190 had the highest sequence identity to the members of the genus Neoroseomonas and was closely related to N.

Uncovering the hidden bacterial ghost communities of yeast and experimental evidences demonstrates yeast as thriving hub for bacteria.

Our major concern was to address "yeast endobacteria" which was based on a few reports in the recent past where bacteria may find yeast as a niche for survival. In this study, we report the microbiota of twenty-nine axenic yeast cultures recovered from different habitats based on their 16S rRNA gene-amplicon metagenomes. Yeasts were identified based on D1/D2 or ITS gene sequences.

Toxicity of Crude Extracellular Products of Aeromonas hydrophila on Rohu, Labeo rohita (Ham.).

In the present study the haemolytic and proteolytic activity of extracellular products (ECP) secreted from Aeromonas hydrophila (CAHH14 strain) were studied with respect to temperature and different time of incubation as well as its lethal toxicity on rohu, Labeo rohita. The strain was isolated from Catla catla (showing abdominal dropsy symptom) collected from the pond of Central Institute of Freshwater Aquaculture (CIFA), Bhubaneswar, India and was characterized on the basis of biochemical tests. The highest production of haemolysin was achieved when the bacteria was grown at 35°C for 30 h.
