This paper demonstrates a systems framework for assessment of environmental impacts from 'green initiatives', through a case study of meso-scale, anthropogenic-biogenic interactions. The following cross-sectoral green initiatives, combining the emerging trends in the North East region of the United Kingdom, have been considered - increasing the vegetation cover; decarbonising road transport; de...

Nitrogen supplementation, which is widely used in winemaking to improve fermentation kinetics, also affects the products of fermentation, including volatile compounds. However, the mechanisms underlying the metabolic response of yeast to nitrogen additions remain unclear. We studied the consequences for Saccharomyces cerevisiae metabolism of valine and ammonium pulses during the stationary phas...

Effects of 1% or 0.5% chitosan (CHI), 10% or 5% aqueous extract of ginger, onion and garlic (GOG) and their composite solutions (1% CHI+10% GOG, 0.5% CHI+5% GOG) on quality and shelf life of stewed-pork were evaluated. Microbiological (total bacterial count), chemical (pH, total volatile basic nitrogen (TVB-N), peroxide value (POV), 2-thiobarbituric acid (TBA)) and sensory characteristics were ...

The aim of this work was to develop simple and fast tests to predict anaerobic biogasification potential (ABP) of ingestates and digestates from a biogas plant. Forty-six samples of both ingestates and digestates were collected within an eight-month observation period and were analyzed in terms of biological and chemical parameters, namely, ABP test, oxygen demand in a 20-h respirometric test (...

The quality of minced kilka (Clupeonella cultriventris caspia) with gum arabic encapsulated (0.3% and 0.5% w/w) and unencapsulated fennel extract (FE) (0.3% and 0.5% w/w) stored at 4°C was examined over a storage period of 15 days. The control and the treated fish samples were analyzed periodically for microbiological (total viable count [TVC] and total psychrotrophic count [TPC]) and chemical ...

A gutless polychaete of the family Siboglinidae, Oligobrachia mashikoi, known in the past as a beard worm of the group Pogonophora, inhabits Tsukumo Bay of the Noto Peninsula in the Sea of Japan. Photographs were taken of this polychaete projecting about one third of the length of its tentacles outside of its tube. The tube protruded several mm from the sea bottom. These are the first field pho...

the aim of this study was to investigate the effects of starters and storage temperature (4 ºc, 25 ºc) onmicrobiological and physicochemical properties, volatile compounds and sensory evaluation of kefir.kefirs produced by kfa and chr. hansen starters were stored at 4 ºc and 25 ºc for 40 days. ph andacidity at 4 ºc did not change (p ≥ 0.05), while at 25 ºc ph and total solid decreased as well a...

In recent years, there has been an increasing interest in using food additives from natural sources to improve taste and also extend the shelf-life of semi-preserved foodstuffs. The aim of this study was to examine the chemical and microbiological changes promoted by a local marinating process in rainbow trout fillets during chilled storage. Fish fillets were immersed in marinades and stored at...
