Binh Chau hot spring locates in Bung Rieng commune, Xuyen Moc district, Ba Ria - Vung Tau province, and is the second hottest hot spring in Vietnam. Up to date, the microbial diversity of this hot spring has been mainly evaluated using the culture-dependent methods, thus, it could not be able to assess all of microorganisms there.

The demand for energy is increasing day by day worldwide due to population growth, industrialization and rising living standards. Geothermal energy, one of the alternative energy sources, is preferred in terms of providing environmentally friendly, quality and regular energy. Our country is rich in geothermal resource potential. However, there are still many unexplored geothermal resources. In this study, fuzzy-AHP method was used to determine the geothermal potential of Ağrı province.

Clarias gariepinus and Oreochromis niloticus are two hot-water fish species of African origin that have been recently reported to occur unnaturally in hot-water resources and springs in the Sakarya River Basin (northwestern Turkey). Within effective planning strategies to maintain native biodiversity, monitoring fishes’ well-being can be useful to evaluate the status of nonnative fish populations and their degree of adaptation to new environments.

Warm winter and hot spring attributed to global warming affected floral development and may induce floral abortion, resulted in poor flowering in litchi. To identify genes potentially involved in litchi floral abortion, six RNA-sequencing (RNA-Seq) libraries of the developing panicles (DPs) under low temperature (LT) conditions and the shrinking panicles (SPs) under high temperature (HT) conditions were constructed.

Amylase producing thermophilic bacterial strain was isolated from Jeori hot water spring, Rampur Bushahr of Shimla district of Himachal Pradesh, India and identified as Bacillus thuringiensis J2 using 16S rRNA gene sequencing and deposited in NCBI gene bank vide accession number |KY990713|. Medium components and process parameters were optimized with respect to substrate concentration, carbon sources, nitrogen sources, incubation period, pH and temperature for an enhanced amylase production.

The aim of this study was to isolate, characterize and identify endophytic bacteria from plants growing along the stream banks in Hot Springs, South Dakota. The bacterial endophytes were isolated, identified and screened in vitrofor morphological features (Gram stain, Gram morphology, and colony morphology). Further, isolates exhibiting difference in morphological features were selected for molecular identification through partial 16S-rRNA gene sequencing.

The aim of this study was to isolate and optimize the growth conditions of thermophilic microorganism from hot springs. The isolation was conducted by using the mineral salt basal medium supplemented with 0.6% yeast extract at 500C. Totally, 33 isolates of thermophilic microorganism were isolated from hot springs at Truong Xuan (Khanh Hoa province) and Binh Chau (Ba Ria - Vung Tau province).

Barley (Hordeum vulgare) is an important crop cultivated across the world. Drought is a major abiotic factor compromising barley yield worldwide, therefore in modern spring barley cultivars superior seed and malting quality characteristics should be combined with reasonable level of drought tolerance.

The thermophile bacteria that came from hot spring, generally, it is thermostable, which it can produce enzyme. For example, there are protease, lipase, and amylase. Amylase produced by bacteria or bacteria amylase is an enzyme that can hydrolyze starch to sugar. The thermostable of amylase resist to high temperature and pH. It has been used on many industrial productions like foods, fermentation, textile, alcohol, paper, pharmaceutical and detergent.

The use of enzymes in a free form is very uneconomical because the enzymes generally cannot be recovered at the end of the reaction. These drawbacks can be overcome by immobilization of the enzyme thereby rendering it more stable and easy to recover and recycle. It is a very effective alternative for gripping the problems of instability, repetitive use and reduction in the cost of enzyme. The aim of this research was to obtain the optimum condition of the making of immobilized amylase beads using a different natural matrix. The result obtain that amylase producing isolate i.e.

Expression of microbial target genes in Escherichia coli is broadly used due to its advantages namely: well established system, easy to manipulate, a huge biomass, high level productivity, safe and inexpensive to grow. Metagenomic technique has been applying in Vietnam recently for effective mining of uncultured gene resources, especially in endemic mini-ecologies such as hot springs where the cell densities are low. DNA metagenome of Binh Chau hot spring was isolated and sequenced by Illumia HiseqTM.
