Sporulating bacteria prefers predation to cannibalism in mixed cultures.

Suitability of MRS-bile Agar for the Selective Enumeration of Mixed Probiotic Bacteria in Presence of Mesophilic Lactic Acid Cultures and Yoghurt Bacteria

Measuring the viability of probiotic microorganisms in food products using plate count methodology is a common practice due to the simplicity (ease of performance), inexpensive and routine testing characters ofthis method. In present study, the suitability of de man rogosa and sharpe agar (MRS) bile agar medium forthe selective enumeration of mixed probiotic bacteria (Lactobacillus ...

Bioleaching of Copper from Low-Grade Ore Using Isolated Bacteria and Defined Mixed Cultures

Microbial Desulfurization of Malaysian Coal in Batch Process using Mixed Culture (RESEARCH NOTE)

Biodesulfurization of coal has been carried out in batch culture of single strain and mixed culture of sulfur oxidizing bacteria. The pure cultures of Thiobacillus thiooxidans and Thiobacillus ferrooxidans utilized inorganic sulfur content of Malaysian coal. The chemolithotroph bacteria were able to grow on coal and metabolize the coal's sulfur content. The batch cultures of coal with 3-5 perce...

Comparison of sterilization reaction rate for Bacillus subtilis and Escherichia coli using UV-visible spectroscopy

Sterilization is a process that eliminates or kills all microbes, including transmissible agents present on a surface, contained in a fluid, medication or biological culture media (UCLA Department Epidemiology). Dry heat sterilization is one of the important methods of eliminating microbes, as it coagulates the proteins in an organism, causing oxidative free radical damage thus leading to cell ...

The Impact of Cannibalism in the Prey on Predator–prey Systems

Cannibalism is ubiquitous in natural communities and has the potential to alter the functional relationship of predator–prey interactions. Although cannibalistic species are frequently subject to predation, the consequences of cannibalism in the prey for predator–prey interactions are poorly understood. Using a dragonfly larvae system, I provide the first experimental evidence that cannibalism ...
