  1. 1. A Comprehensive Review of the Factors Influencing the Environmental Impact of different Species bred in Closed Land-based Recirculating Aquaculture Systems

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Siri Samuelsson; [2022]
    Keywords : Recirculating aquaculture system; renewable electricity; Feed Conversion Ratio; environmental impact; freshwater eutrophication; climate change; land use; cumulative energy use; acidification; Earth and Environmental Sciences;

    Abstract : Today the future supply of seafood is threatened due to human activities which, among other things, has led to overfishing. However, more environmental friendly initiatives of producing seafood have emerged, such as Recirculating Aquaculture Systems (RASs). READ MORE

  2. 2. Lipid content and profile of Rhodotorula toruloides during fermentation

    University essay from SLU/Department of Molecular Sciences

    Author : Khairul Kibria; [2021]
    Keywords : Rhodotorula toruloides; fatty acids; lipid class; triglycerides; phospholipid; gas chromatography;

    Abstract : Oleaginous yeast such as Rhodotorula toruloides is a promising organism for production of lipids from lignocellulosic substrates. Microbial lipids have potential applications in energy, food, feed and pharmaceutical industry, because most of the lipids are triglycerides with long chain fatty acids that are comparable to typical vegetable oils and can be obtained without arable land requirement.

  3. 3. Ciona (Ciona intestinalis) as a source of fibre for chickens : Effects on productive performance, organs weights and caecal microbiota

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Qasim Mashood; [2019]
    Keywords : Broiler; dietary fibre; ciona; cellulose; gut microbiota; sodium;

    Abstract : In this experimental study broiler birds were fed in a randomized block design for 32 days on a control diet (C) based on wheat and soy bean meal and two experimental diets containing 2% (C2) and 4% ciona meal (C4) to examine the suitability of Ciona intestinalis in poultry feed as a source of fibre and its effects on growth performance, microbial composition and digestive traits. Luminal content was taken from caeca at day 12 and 32 and analysed for microbiota profile and short chain fatty acids (SCFA). READ MORE

  4. 4. Investigation of a CO-Production of Substitute Natural Gas and Biomethanol Plant Compared to Stand Alone Biomethanol Plant

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Susanne Brixland; [2019]
    Keywords : biomethanol; SNG; substitute natural gas; co-production; gasification; gasifier; biomass; syngas; chemical engineering; kemiteknik; Chemistry; Technology and Engineering;

    Abstract : Climate change is one of humanities greatest challenges; the greenhouse gases in the atmosphere are still increasing. There is not one solution that will fix this problem several different products, raw material and technologies are required to take the steps towards a renewable society. READ MORE

  5. 5. Baltic blue mussel (Mytilus edulis L.) and black soldier fly (Hermetia. illucens) combined with pea protein concentrate as protein sources in feed for rainbow trout (Oncorhynchus mykiss)

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Xiaoqing Cui; [2019]
    Keywords : aquaculture; rainbow trout; Baltic blue mussel; black solider fly larvae; digestibility; protein; fishmeal replacement;

    Abstract : A feeding trial was conducted for 9 weeks to test the growth performance, nutrient retention and digestibility in rainbow trout (Oncorhynchus mykiss) in order to assess the potential of Baltic blue mussel meal (Mytilus edulis L) and black solider fly larvae (Hermetia illucens) meal as protein sources. The dietary treatments consisted of one control diet based on high quality fishmeal, one control diet based on pea protein concentrate for testing dietary palatability and two fishmeal-free experimental diets where approximately 20% of the crude protein from the fishmeal was replaced with the protein from either de-shelled blue mussel meal or larvae meal on a dry matter basis.
