In this study, Halomonas boliviensis was cultivated on bakery waste hydrolysate and seawater in batch and fed-batch cultures for polyhydroxybutyrate (PHB) production. Results demonstrated that bakery waste hydrolysate and seawater could be efficiently utilized by Halomonas boliviensis while PHB contents between 10 and 30% (w/w) were obtained. Furthermore, three methods for bakery waste hydrolys...

A mutual exclusion algorithm is presented that has four desired properties: (1) it satisfies FIFO fairness, (2) it satisfies localspinning, (3) it is adaptive, and (4) it uses finite number of bounded size atomic registers. No previously published algorithm satisfies all these properties. In fact, it is the first algorithm (using only atomic registers) which satisfies both FIFO and local-spinni...

Lower respiratory symptoms in bakery workers may be induced by wheat flour and endotoxins. We hypothesized that endotoxins from wheat flour may stimulate innate immunity and that interleukin-18 (IL-18) gene polymorphisms may affect their regulatory role in innate immune responses to endotoxins. To investigate the genetic contribution of IL-18 to sensitization to wheat flour, we performed a gene...

A survey of dust exposure, respiratory symptoms, lung function, and response to skin prick tests was conducted in a modern British bakery. Of the 318 bakery employees, 279 (88%) took part. Jobs were ranked from 0 to 10 by perceived dustiness and this ranking correlated well with total dust concentration measured in 79 personal dust samples. Nine samples had concentrations greater than 10 mg/m3,...

Acrylamide is a by-product of the Maillard reaction and is potentially carcinogenic to humans. It is found in a number of foods with higher concentrations in carbohydrate-rich foods and moderate levels of protein-rich foods such as meat, fish and seafood. Acrylamide levels in food distributed in vending machines placed in public areas of the city of Perugia were analysed by high-performance liq...

Coke oven, which is a large industrial furnace, is complex in structure. A two-dimensional structure diagram can hardly help one observe the inner structure of a coke oven or master its working principle comprehensively. In order to solve this problem, a complete 3D digital model of a coke oven is generated by assembling the three-dimensional models of coke oven components created with SketchUp...

Fungal alpha-amylase is an important occupational allergen in the bakery industry. Epidemiologic studies focusing on the relationship between alpha-amylase allergen exposure and work-related respiratory allergy, however, have not been reported yet. In this cross-sectional study, sensitization to occupational allergens and work-related symptoms were studied in 178 bakery workers and related to a...

Whole-grain bakery products and cereals are valuable sources of dietary fiber, vitamins, and trace elements. However, the presence of phytate, could decreases mineral bioavailability due to its chelating properties. In this study, the effect of fermentation and baking on the phytate content of different bakery products was measured by HPLC; the mineral availability in bakery products during pro...

The door to a microwave oven forms part of the heating cavity, allowing access to the oven interior. The seal around the door is never perfect, so electromagnetic fi elds will leak out of the oven, potentially interfering with other electrical equipment or exceeding safety limits for power levels in human operators. Oven designs have to meet legal requirements for the amount of power which can ...

background edible salt is the most commonly used food additive worldwide. therefore, any contamination of table salt could be a health hazard. objectives the present study aimed to determine the levels of heavy metals in table and bakery refined salts. materials and methods eighty-one table refined salt samples and the same number of bakery refined salt samples were purchased from retail market...
