TL;DR: The optical method of De Ley et al. (1970) for determining DNA/DNA homologies was reexamined and the agreement is excellent above a degree of binding of 25-30%.

TL;DR: Six isolates of a new genus of anaerobic archaebacteria, named Pyrodictium, were isolated from a submarine solfataric field off Vulcano, Italy, and formed highly unusual networks of fibres.

TL;DR: The absence of an immunochemical cross-reaction of the enzyme from Thermococcus with those from Thermoproteus, Desulfurococcus, Sulfolobus and Thermoplasma and the extent of cross-hybridization of the 16S rRNA with DNAs of other thermoacidophiles place it into the thermo Acidophilic branch of the archaebacteria as a novel isolated genus.

TL;DR: The extremely halophilic rod-shaped bacterium, strain R-4, has features very different from other known Halobacterium species, including a high excess of acidic over basic amino acids in its proteins, a cell wall lacking peptidoglycan, and ether-linked diphytanyl lipids.

TL;DR: Exposures to air for up to 30 h were without effect on the number of colony forming units whereas longer periods of contact with oxygen led to a rapid decrease in viability, leading to 99% kill within 10 h.

TL;DR: The presence of glycerol diethers suggests that this organism may have had an evolutionary episode similar to archaebacteria, but the apparent stereochemistry and absence of isopranoid-branched side chains suggests that it is perhaps more likely a eubacterium capable of ether lipid biosynthesis.

TL;DR: Thermofilum pendens, an anaerobic, sulfur respiring archaebacterium representing a novel genus, possibly even a novel family, of the extremely thermophilic mildly acidophilic Thermoproteales, has been isolated from an Icelandic solfataric hot spring.

TL;DR: Chemical, morphological and physiological data indicate a close relationship between Brevibacterium imperiale (Steinhaus), "Corynebacterium laevaniforms" (Dias and Bhat) and the species Microbacteria lacticum (Orla-Jensen) and it is suggested that B. imperiale and "C. laevAniformans" be reclassified in a redefined genus Microb bacteria.

TL;DR: DNA hybridization studies revealed a high DNA-DNA homology within the new isolates but only a low relationship to S. ureae, which belong to a new species, for which the name Sporosarcina halophila is proposed.

TL;DR: A group of 6 strains of obligately thermophilic spore-formers is described as a novel species named Bacillus thermoglucosidasius, which produce terminally swollen sporangia and exo-oligo-1,6-glucosidase in large amounts.

TL;DR: These isolates are considered as representatives of the new species Lactobacillus kefir sp.

TL;DR: Although the methods reported were developed for study of methanogens with polyclonal antibody probes, they can be applied to any other group of organisms with antigenic mosaics and to studies with panels of monoclonal antibodies.

TL;DR: Two subspecies of Lactobacillus delbrueckii subsp.

TL;DR: A group of 8 heterofermentative Lactobacillus strains were isolated from raw vacuum-packaged, as well as SO(2)-treated, minced beef, in the course of shelf life studies on this product, finding their pattern of sugar metabolism seems to differ from the traditional HMP-pathway typical of the heterfermentative lactobacilli.

TL;DR: The genetic data indicate that the genus Arthrobacter contains two nuclei whose members can be distinguished from each other by the peptidoglycan type and the menaquinone composition.

TL;DR: DNA-DNA homology and several phenotypical characteristics, such as murein type and patterns of carbohydrate fermentation, and isoenzymes of L-lactate dehydrogenase and of transaldolase in the type strains of all species of the genus Bifidobacterium listed in the Approved Lists of Bacterial Names are determined.

TL;DR: A pathway for styrene metabolism through the intermediary formation of phenylacetate and o-hydroxyphenylacetic acids which is further oxidized via homogentisate is suggested and discussed.

TL;DR: DNA base compositions, DNA/DNA homologies and lipid studies were performed on some dairy and skin coryneform bacteria in an attempt to clarify their taxonomy and indicate the dairy andskin isolates represent two new species of the genus Brevibacterium.

TL;DR: Chemical, biochemical and morphological data indicate a close relationship between the taxa "Microbacterium liquefaciens", Arthrobacter flavescens, Arth Robacter terregens, "Corynebacterial barkeri", Curtobacterium saperdae and Curtobacteria testaceum, and it is proposed that the above taxa be reclassified in a new genus Aureobacteria.

TL;DR: Alcaligenes spec.

TL;DR: Sulfolobus acidocaldarius, S. brierleyi and S. solfataricus possessed caldariellaquinone (6-(3,7,11,15,19,23-hexamethyltetracosyl)-5-methylthiobenzo-[b]-thiophen-4,7-quinone) as their major lipoquinone.

TL;DR: Ninety-eight strains, representing all Acetobacter species and subspecies from the Approved Lists of Bacterial Names, were examined in a numerical analysis of 177 phenotypic features and compared to ninety-eight Gluconobacter and seven Frateuria strains.

TL;DR: Lactobacillus plantarum isolated from fish is unable to degrade any other amino acid than tyrosine and arginine, the former being converted to tyramine and the latter to ornithine and ammonia in an energy yielding reaction.

TL;DR: Deoxyribonucleic acid-DNA-DNA hybridization and physiological studies on 15 strains of S. sciuri subsp.

TL;DR: The isodiametric bacteriophage P008 is wide-spread in German cheese factories and its ultrastructural peculiarity whiskers originating from its collar were detected, suggesting the presence of cohesive ends in P008 DNA.

TL;DR: Four new isolates from different saline habitats are described as the new species Rhodopseudomonas marina, which grows photo-trophically in the light under anaerobic conditions, but is also capable of growing in the dark under microaerophilic or anaerilic conditions, depending on the carbon source.

TL;DR: Lactobacillus, together with Streptococcus and Bacillus, constitute a super-cluster within the 'clostridium' sub-branch of Gram-positive eubacteria showing a low guanine plus cytosine content of their deoxyribonucleic acid.

TL;DR: In 1970 two new species within the so-called subgenus "Streptobacterium" Orla-Jensen of the genus Lactobacillus were described and have so far not been included in the "Approved Lists of Bacterial Names" (Skerman et al., 1980).

TL;DR: A new heterobasidiomycetous genus, Cystofilobasidium, based on Rhodosporidium capitatum is described, characterized by teliospores which give rise to filobAsidiaceous basidia, sessile primary basidiospore which remain attached to the basidium, and a yeast phase developing from buds produced by the primary spores.

TL;DR: "Lactobacillus viridescens subsp. halotolerans" and "LactOBacillusviridescenssubsp. minor", not included in the Approved Lists of Bacterial Names, are reinvestigated and described as the new species Lacobacillin halotolerance sp.
