Characterization of spiny lobsters from Bangladesh waters using morphology, COI and 16S rRNA sequences

Heliyon, 2022
This study aims to taxonomically identify and characterise the phylogenetic relationships of spiny lobsters based on mitochondrial cytochrome c oxidase I (COI) and 16S rRNA genes from Bangladesh waters.

Variable rRNA gene copies in extreme halobacteria

Nucleic Acids Research, 1988
Using PFG electrophoresis techniques, we have examined the organization of rRNA gene in halobacterium species. The results show that the organization of rRNA genes among closely related halobacteria is quite heterogeneous. This contrasts with the high degree of conservation of rRNA sequence (1).

Characterization of Streptomyces venezuelae ATCC 10595 rRNA gene clusters and cloning of rrnA [PDF]

Journal of Bacteriology, 1996
Streptomyces venezuelae ATCC 10595 harbors seven rRNA gene clusters which can be distinguished by BglII digestion. The three rRNA genes present in each set are closely linked with the general structure 16S-23S-5S. We cloned rrnA and sequenced the 16S-23S spacer region and the region downstream of the 5S rRNA gene.

Magnification of Genes Coding for Ribosomal RNA in Saccharomyces cerevisiae [PDF]

, 1977
When a strain of Saccharomyces cerevisiae monosomic for chromosome I and initially deficient for 25% of the genes coding for ribosomal RNA is repeatedly subcultured, the number of these genes increases to and remains stable at the number in the wild type.

Louse (Insecta : Phthiraptera) mitochondrial 12S rRNA secondary structure is highly variable [PDF]

, 2002
Lice are ectoparasitic insects hosted by birds and mammals. Mitochondrial 12S rRNA sequences obtained from lice show considerable length variation and are very difficult to align.

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

FEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Characterisation of dairy strains of Geobacillus stearothermophilus and a genomics insight into its growth and survival during dairy manufacture : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Microbiology at Massey University, Palmerston North, New Zealand [PDF]

, 2016
The thermophilic bacilli, such as G. stearothermophilus, are an important group of contaminants in the dairy industry. Although these bacilli are generally not pathogenic, their presence in dairy products is an indicator of poor hygiene and high numbers ...

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

FEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Osteoradionecrosis contains a wide variety of cultivable and non-cultivable bacteria

Journal of Oral Microbiology, 2010
Background: Direct microscopy, anaerobic culture and DNA–DNA hybridization have previously demonstrated an association between microorganisms and osteoradionecrosis (ORN).
