Physiology of purple sulfur bacteria forming macroscopic aggregates in Great Sippewissett Salt Marsh, Massachusetts [PDF]
Purple bacterial aggregates found in tidal pools of Great Sippewissett Salt Marsh (Falmouth, Cape Cod, MA) were investigated in order to elucidate the ecological significance of cell aggregation. Purple sulfur bacteria were the dominant microorganisms in

ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Bioleaching of Tetrahedrite by Iron- and Sulfur-Oxidizing Bacteria
Abstract This study describes the bioleaching of a flotation concentrate by acidophilic iron- and sulfur-oxidizing bacteria at ambient temperature in shake flasks. The concentrate was prepared from polymetallic Ag–Cu–Sb–siderite ores from Rožňava (Slovakia) and consisted of tetrahedrite and siderite, with small ...

Microbial ecology of anammox bacteria in estuarine and oxygen minimum zone environments [PDF]
Anammox (anaerobic ammonium oxidation) is an environmentally significant process with great importance for global biogeochemical cycles. This process is mediated by a unique suite of phylogenetically distinct chemolithoautotrophic bacteria which ...

Fossil carotenoids and paleolimnology of meromictic Mahoney Lake, British Columbia, Canada [PDF]
Vertical distribution of fossil carotenoids in a sediment core from meromictic Mahoney Lake was studied. Besides okenone and demethylated okenone, lutein and zeaxanthin and-carotene isomers were identified.
