BACKGROUND Goat milk production in Shaanxi province is dominant in China, but the product is mainly infant formula and adult milk powder; product homogeneity is serious and has no goat yoghurt with probiotic culture. METHODS The effect of bacteria proportion (1:3:1, 1:2:1, 1:1:1, 2:1:1, 3:1:1) on pH, acidity, and viable counts and sensory evaluation of goat milk fermented by probiotics includ...

abstract: yoghurt is a popular healthy food, consumed by many people. the popularity of this product made it possible to use it as a base in order to produce probiotic preparations. prebiotics are used for better growth and survival of probiotic bacteria as well as to improve organoleptic, rheological and technological properties of probiotic yoghurt. the aim of this research was to study physi...

Drilling operations of petroleum generate oily wastes. The disposal of a significant amount of oil-based drill muds has caused soil contamination and critical environmental impacts in the last decades.The current study aimed to investigate the potential of microbial remediation for an aged oil-based drilling waste and to monitor the fluctuation in microbial population throughout a ...

Today, microbial drinking water quality is monitored through either time-consuming laboratory methods or indirect on-line measurements. Results are thus either delayed or insufficient to support proactive action. A novel, optical, on-line bacteria sensor with a 10-minute time resolution has been developed. The sensor is based on 3D image recognition, and the obtained pictures are analyzed with ...

The effect of growth temperature on the virulence of a strain of broth-grown serogroup 1 Legionella pneumophila (Wadsworth F889) was examined by growing the bacterium at different temperatures and then infecting guinea pigs (by intratracheal injection) and guinea pig alveolar macrophages. The 50% lethal dose for guinea pigs infected with 25 degrees C-grown F889 was log10 5.0 CFU and that for 41...

Community composition and antibiotic resistance of tap water bacteria are still not known well enough. This study fills the gaps in knowledge regarding this matter. To provide representativeness collected samples, were concentrated from huge amounts water, using filtration membranes monthly during continuous, semi-annual study, covering winter spring seasons. Biomass was investigated both a cul...

BACKGROUND There are no established guidelines for the surgical prep of an external fixator in the operative field. This study investigates the effectiveness of different prep solutions and methods of application. METHODS Forty external fixator constructs, consisting of a rod, pin, and pin to rod coupling device, were immersed in a broth of Staphylococcus aureus (lux) for 12 hours. Constructs...

The relationship between bacterial counts and endotoxin concentrations in air samples was studied. Selective EMB medium favored the growth of a larger portion of airborne gram-negative bacteria than LES Endo or MacConkey medium and was a good predictor of the endotoxin levels determined with a chromogenic Limulus assay of the air of wastewater treatment plants. The bacterial counts determined w...

Yogurt powder is fermented milk processed in the form of dry yogurt, and has advantages such as stability, storability, convenience, and portability. China and Vietnam are important export target countries because of the increased demand for dairy products. Therefore, we surveyed dairy product standardization in order to establish an export strategy. Lactic acid bacteria counts are unregulated ...
