Symbiotic Bacteria and Phosphorescence [PDF]

open access: bronzeNature, 1922
IN Prof. Gamble's review of Buchner's “Tier und Pflanze in intrazellularer Symbiose” (NATURE, May 6) reference is made to the work of Pierantoni, according to whom the luminous organs of cephalopods are “essentially cultures of bacteria in media suitable for their nutrition and in situations favourable for obtaining oxygen.”

Symbiotic stars [PDF]

open access: yesNature, 1981
AbstractI review our current knowledge of symbiotic stars. A great many papers have graced the literature in the fifty years of their study, and many data are available on the spectral variations at optical wavelengths these stars undergo. I do not give extensive references to those data, for previous reviews have done so quite adequately.

The therapeutic use of symbiotics [PDF]

open access: yesABCD. Arquivos Brasileiros de Cirurgia Digestiva (São Paulo), 2014
INTRODUCTION: Functional foods are health promoters and their use is associated with reduced risk of chronic degenerative and non-transmissible diseases. Examples are symbiotic. The association of one (or more) probiotic with a one (or more) prebiotic is called symbiotic, being the prebiotics complementary and probiotics synergistic, thus presenting a ...

Swift observations of the 2015 outburst of AG Peg -- from slow nova to classical symbiotic outburst [PDF]

open access: yes, 2016
Symbiotic stars often contain white dwarfs with quasi-steady shell burning on their surfaces. However, in most symbiotics, the origin of this burning is unclear. In symbiotic slow novae, however, it is linked to a past thermonuclear runaway. In June 2015,

Evolutionary dynamics of insertion sequences in relation to the evolutionary histories of the chromosome and symbiotic plasmid genes of Rhizobium etli populations [PDF]

open access: yes, 2010
Insertion sequences (IS) are mobile genetic elements that are distributed in many prokaryotes. In particular, in the genomes of the symbiotic nitrogen-fixing bacteria collectively known as rhizobia, IS are fairly abundant in plasmids or chromosomal ...

The genome of Rhizophagus clarus HR1 reveals a common genetic basis for auxotrophy among arbuscular mycorrhizal fungi

open access: yesBMC Genomics, 2018
Background Mycorrhizal symbiosis is one of the most fundamental types of mutualistic plant-microbe interaction. Among the many classes of mycorrhizae, the arbuscular mycorrhizae have the most general symbiotic style and the longest history.

Symbiotic Stars [PDF]

open access: yesSymposium - International Astronomical Union, 1969
There are some arguments that the symbiotic stars are binary, where one component is a red giant and the other component is a small hot star which is exciting a nebula. The symbiotic stars belong to the old disc population. Probably, symbiotic stars are just such an evolutionary stage for double stars as planetary nebulae for single stars.

Symbiotic Associations

open access: yesACADIA proceedings, 2016
Soil contamination poses a series of important health issues, following years of neglect, constant industrialization, and unsustainable agriculture. It is estimated that 30% of the total cultivated soil in the world will convert to degraded land by 2020 (Rashid et al. 2016).

Penggunaan Limbah Industri Jamu dan Bakteri Asam Laktat (Lactobacillus sp.) sebagai Sinbiotik untuk Aditif Pakan Terhadap Kualitas Interior Telur Ayam Ras Petelur

open access: yesJurnal Peternakan Indonesia, 2017
This study was to determine the effect of synbiotic as a feed additive of laying hens for the interior egg quality. This study used 100 laying hens which are 40 weeks old as the material. The body weight of laying hens are 1.81 ± 0.12 grams.
