Halophiles are salt loving organisms requiring about 3M5M NaCl concentration in their growth. Eleven halophilic archaea and nine bacteria were isolated from various samples from extremely high salt concentrated ecosystem from western parts of Maharashtra, India. The isolates were studied using morphological and biochemical studies. Most of the isolates were gram negative in nature. These organi...

Article history: Received on: 11/04/2016 Revised on: 09/05/2016 Accepted on: 24/06/2016 Available online: 29/10/2016 Drug resistance in microorganisms is an emerging phenomenon that poses challenges to public health and treatment. The reservoir of drug resistance genes found in the resistome of environmental isolates in aquatic saline systems has been augmenting continuously. The spread of drug...

Abstract. Aerosols play a crucial role in cloud formation. Biologically derived materials from bacteria, fungi, pollen, lichen, viruses, algae, and diatoms can serve as ice nucleating particles (INPs), some of which initiate glaciation clouds at relatively warm freezing temperatures. However, determining the magnitude interactions between biologically INPs remains significant challenge due to d...

Atomic resolution structures of a sensory rhodopsin phototaxis receptor in haloarchaea (the first sensory member of the widespread microbial rhodopsin family) have yielded insights into the interaction face with its membrane-embedded transducer and into the mechanism of spectral tuning. Spectral differences between sensory rhodopsin and the light-driven proton pump bacteriorhodopsin depend larg...

Haloarchaea are the dominant microbial flora in hypersaline waters with near-saturating salt levels. The haloarchaeal diversity of an Australian saltern crystallizer pond was examined by use of a library of PCR-amplified 16S rRNA genes and by cultivation. High viable counts (10(6) CFU/ml) were obtained on solid media. Long incubation times (> or =8 weeks) appeared to be more important than the ...
