T he fishing and fish processing industry has experienced tremendous growth in recent years. In 1990 the Food and Agriculture Organisation (FAO) estimated that the number of people engaged in fishing, aquaculture, and related activities worldwide doubled to 28.5 million from 1970. Among these workers 52% worked aboard fishing trawlers, 32% were involved in aquaculture production (marine and fre...

  Background and purpose: CO2 is the main cause of greenhouse effect. Previous studies have shown that CO2 in methane and coal flue gas can lead to microalgae growth. The aim of this research was to study the CO2 biofixation by Spirulina and injecting kerosene flue gas. Materials and methods: A photo bioreactor was fabricated in which kerosene flue gas and air were separately injected. The ph...

The rapid development of modern society has resulted in an increased demand for energy, mainly from fossil fuels. The use of this source of energy has led to the accumulation of carbon dioxide (CO2) in the atmosphere. In this context, microalgae culturing may be an effective solution to reduce the CO2 concentration in the atmosphere, since these microorganisms can capture CO2 and, simultaneousl...

Research was conducted to determine the effects of level of supplementation with quebracho condensed tannins (CT) on in vitro ruminal fluid gas production, in vivo ruminal fluid protein fractions, bloat dynamics, and ADG of steers grazing winter wheat. Two experiments were conducted to 1) enumerate the effect of ruminal fluid from steers fed quebracho CT (0, 1, and 2% CT/kg of DMI) on in vitro ...

Effects of water stress on ethylene evolution from excised leaf segments and intact plants of wheat (Triticum aestivum L. cv Katepwa) were studied. Excised leaf segments of 8 day or 6 week old plants were dried until they lost 8% of their fresh weight (water potential about -2.3 megapascals). These and nondried control leaf segments (water potential about -1.0 megapascal) were sealed in glass t...

An extensive number of metabolic experiments have been carried out at the former Oskar-Kellner-Institute, now the ›Oskar Kellner‹ Research Unit of Nutritional Physiology at the Research Institute for the Biology of Farm Animals (FBN), Dummerstorf, on cattle, pigs and humans. Their expired amounts of CO2 having been compiled and stratified with regard to various performance and nutrition levels....

An experiment was carried out to study the effect of different forms of wheat (airtight silo stored whole wheat, conventionally stored whole wheat, and ground wheat included in pellets) and dietary xylanase addition on production results and gastrointestinal characteristics of broiler chickens. Ileal viscosity, pancreatic digestive enzyme activities, and the composition and activity of the inte...
