Environmental Science and Technology, 2020 Hyporheic zones are the water-saturated flow-through subsurfaces of rivers which are characterized by the simultaneous occurrence of multiple physical, biological, and chemical processes. Two factors playing a role in the hyporheic attenuation of organic

Horizontal DNA transfer mechanisms of bacteria as weapons of intragenomic conflict [PDF]
, 2016 Horizontal DNA transfer (HDT) is a pervasive mechanism of diversification in many microbial species, but its primary evolutionary role remains controversial.

Bacterial Inactivation of Transforming Deoxyribonucleate [PDF]
Journal of Bacteriology, 1971 Competent and noncompetent bacteria are able to bind deoxyribonucleate (DNA). The consequence of this binding is different for the two types of bacteria. Competent bacteria are able to utilize the DNA for transformation. DNA exposed to noncompetent bacteria loses its biological activity with a coincident reduction in the double-stranded molecular ...

The bacterial transformation of abietic acid [PDF]
Biochemical Journal, 1968 An Alcaligenes species, which was isolated from soil, can utilize abietic acid as its sole carbon source. During growth, the bacterium transforms abietic acid into 5α-hydroxyabietic acid (I, R=OH), a product considered to be 7β-hydroxy-13-isopropyl-8ξ-podocarp-13-en-15-oic acid (II, R=H) and a compound, C20H28O3, which is believed to be an epoxy-γ ...

The replication of DNA in Escherichia coli [PDF]
, 1958 Studies of bacterial transformation and bacteriaphage infection (1-5) strongly indicate that deoxyribonucleic acid (DNA) can carry and transmit hereditary information and can direct its own replication.

Genetic transformation of Torenia fournieri L. mediated by Agrobacterium rhizogenes [PDF]
, 2006 The transformation of Torenia fournieri L. mediated by Agrobacterium rhizogenes was studied. Almost all roots induced by four bacterial strains, R1000, R1601, A4 and R1205 were putative hairy roots.

Early-detection and classification of live bacteria using time-lapse coherent imaging and deep learning [PDF]
Light: Science & Applications (2020), 2020 We present a computational live bacteria detection system that periodically captures coherent microscopy images of bacterial growth inside a 60 mm diameter agar-plate and analyzes these time-lapsed holograms using deep neural networks for rapid detection of bacterial growth and classification of the corresponding species.

Bioremediation of halogenated compounds: comparison of dehalogenating bacteria and improvement of catalyst stability [PDF]
, 2006 Five bacterial strains were compared for halogenated compounds conversion in aqueous media. Depending on the strain, the optimal temperature for dehalogenase activity of resting cells varied from 30 to 45 degrees C, while optimal pH raised from 8.4 to 9 ...
