Recovery of metabolites from fermentation broth by solvent extraction can be used to optimize fermentation processes. End-product reutilization, low product concentration, large volumes of fermentation broth and the requirements for large bioreactors, in addition to the high cost largely contributed to the decline in fermentative 2, 3-butanediol production. Extraction can ...
Vegetables may be preserved by fermentation, direct acidification, or a combination of these, along with pasteurization, to yield products with an extended shelf life and enhanced safety. Effect of lowering the pH, either by adding acid or lactic fermentation, on thermal process requirements for canned vegetables was investigated. Malic acid was preferred for acidification of canned vegetables...
Abstract. This paper describes a dataset consisting of 47 hyperspectral-reflectance measurements plastic litter samples. The samples include virgin and real from the Port Antwerp. They were measured in dry conditions Flemish Institute for Technological Research (VITO) calibration facility, selection also wet submerged water tank at Flanders Hydraulics. construction on top allowed us to submerge...
Four cultivars of olive, Kalamata, Marri, Zard and Fishmi were obtained from Roodbar town and treated with two methods, natural and controlled fermentation with Lactobacillus plantarum as a starter culture at 25°C for 100 days. HPLC analysis experiments were conducted during the whole study period. A higher level (1.08% w/w) of total acidity was produced in Fishmi cultivar especially in the nat...
these days, most of the marine structures which are constructed and used in persian gulf, are made of st37 steel. due to oil and gas sources excavated, the number of these structures is constantly increasing. on the other hand, these types of structures are exposed to corrosive environments and it is seriously critical for these structures to be used for many years. coal tar epoxy (trade name),...
In 1942, The Japanese Occupation of Singapore (1942-1945) interrupted British rule in and paved the way for island-city’s independence 1965. scholarly literature on this dramatic traumatic period usually focus military aspects capitulation to invasion or submerge officers civilian administrators’ efforts mobilize discipline children youth within broader examination social policies. This article...
BACKGROUND The use of a multistarter fermentation process with Saccharomyces cerevisiae and non-Saccharomyces wine yeasts has been proposed to simulate natural must fermentation and to confer greater complexity and specificity to wine. In this context, the combined use of S. cerevisiae and immobilized Starmerella bombicola cells (formerly Candida stellata) was assayed to enhance glycerol concen...
normal 0 false false false en-us x-none fa background: frozen dough technology makes it possible to access fresh bread with a minimum need for equipment and with minimal skilled personnel at any time. in this study the impact of freezing rate and degree of pre-fermentation on quality factors of s angak frozen dough and its bread was assessed. methods: the pre-fermentation was between 0 and 120 ...
Fermentation is a key step in obtaining fine cocoa through the formation of potent aroma precursors. The fermentation level of cocoa beans is traditionally assessed by measuring the amount of ammonia nitrogen (NH₃) using the time-consuming Conway technique. Near infrared spectroscopy (NIRS), a rapid and efficient tool, was used to analyze NH₃ levels in several hundred cocoa samples at different...
The object of research is a production of antibiotics by fed batch fermentation. An intelligent system with a structure of neural network and a genetic algorithm are used in nonparametric modeling of the fermentation process. The goal is to build a model for the prediction of fermentation eeciency. A priori knowledge of experts, who are controlling the production of antibiotics in industry, is ...
