  • Qualitative algal analysis from the fish-gut: Tested in the rice fish cropping system

    Abstract: Algae constitute a major proportion of fish food in rice-fish culture system. Study of algal preferences and their availability in the natural environment might be important for developing natural fish feed. Preparation of formulated feeds using under-exploited materials such as algae not only reduces production costs, but also increases procurement accessibility of locally available ...

  • Lg Sonic Ultrasonic Algae and biofilm control for irrigation case study

    Water used for irrigation can contain high levels of nutrients, some of these nutrients are beneficial for the plants watered, but can also lead to extensive algal growth. Algae in irrigation tanks can clog the irrigation system and can also be spread over the irrigated area. In addition, some types of fungus, also present in these waters, can be harmful for the plants grown. Therefore the ...

  • The Multiple Application of CRISPR-Cas9

    CRISPR-Cas9 gene editing technology can target virtually any genomic location of choice by utilizing a short RNA guide, then cut the sequence with the Cas9 protein. Compared with traditional gene editing technologies, the CRISPR-Cas9 system is both faster and more efficient. The CRISPR-Cas9 system currently has a wide ...

  • Pretreatment of brewery effluent to cultivate Spirulina sp. for nutrients removal and biomass production

    Due to the low concentration of nitrate and high contents of organics, brewery effluent was not suitable for the cultivation of Spirulina sp. This work changed the nutrient profile of brewery effluent effectively by dilution, addition of nitrate, and anaerobic digestion. The result showed that the optimum dilution rate and NaNO3 addition for brewery effluent were 20% and 0.5 g/L, ...

  • Simulations of nutrient emissions from a net cage aquaculture system in a Brazilian bay

    Hydrodynamics and transport simulations were conducted with the modeling software TELEMAC-2D on Icó-Mandantes bay, a branch of the Itaparica reservoir. The bay has a maximal operational water level amplitude of 5 m and is suffering from eutrophication and algae bloom. Therefore, we investigated low and high water level scenarios with two different high resolution meshes, with the purpose to ...

  • Seasonal Dynamics of Periphyton in a Large Tropical Lake

    Tropical aquatic systems are generally assumed to have little seasonality in productivity patterns. However, this study indicated that there was substantial seasonal variation in epilithic productivity and biomass in tropical Lake Tanganyika, due primarily to seasonal patterns in lake hydrodynamics that influence nutrient availability. Although they support much of the lake’s biological ...

  • LG Sound, controlling algae in irrigation reservoirs

    Algae growth in irrigation water can cause a serious problem. Algae in irrigation tanks can clog the entire irrigation system, such as the pumps, filters, drip-installation and sprinkler nozzles. Besides that the algae and their by-products can also be spread over the irrigated area. In addition, some types of fungi, also present in these waters, can be harmful for the plants grown. Typical ...

  • Nitrogen and phosphorus pollution alter the mutual relationship between corals and algae

    phosphorus pollution change the relationship between the pistillata and the algae living inside its tissues, a recent study has found. The researchers say the pollutants, mainly from urban and agricultural discharges, affect algae photosynthesis and the essential transfer of carbon from algae to the coral. Nitrogen and phosphorus pollution change the relationship between the tropical coral ...

  • On biologically produced nanomaterials

    Living organisms produce a wide variety of nano-sized materials or nano-structured materials to preserve their species on the planet. As Biologically Produced Nano Materials (BPNM) form according to the genetic information obtained in the process of their evolution, its shape or composition is well stabilised, controlled and regulated, and it can be easily mass-produced with environmental ...

  • Simple Quantitative Measurement of Nannochloropsis Micro Algae in Water Using Shimadzu UV Micro Algae Analysis System

    Global warming due to the burning of fossil fuels is now widely recognized as a problem, and among the alternatives to fossil fuels, the extraction of fuel from micro algae has been actively investigated in recent years. While the yield per unit area of micro algae is high, and harvesting is possible year round, these advantages are offset by many challenges in the development process that ...

  • Algae control in irrigation case study

    Reduction of aerobic bacteria and algae in irrigation reservoir Analyzed parameters After finalizing the test the following was observed: strong reduction in algae and aerobic bacteria concentration. This lower amount in micro-organism concentration, in the water leads to lower biochemical oxygen demand (BOD). This subsequently leads to the improvement of the quality of the ...

  • Effects of nanopolystyrene on the feeding behavior of the blue mussel (Mytilus edulis L.)

    As the industrial production of nanoplastic and the degradation of microplastic into smaller particles at sea increase, the potential amount of nanoplastics in the marine environment rises. It has been reported that mussels uptake 100‐nm polystyrene (PS) beads; to date, however, the effects of this uptake on the organism are unknown. Here we investigated the effects of 30‐nm PS on the feeding ...

  • Ecological swimming pond case study

    In spring 2009 LG Sound installed an LG Sonic in an ecological swimming pond in France. This pond has been suffering from the growth of filamentous algae for a long period of time. Even when the algae where removed, they grew back within a couple of days. Swimming or any other recreational use was made impossible in this pond. The LG Sonic products can shift the balance in a watery ecosystem to a ...

  • Development of algae–based technology to mitigate energy crisis in coal mining areas: a critical review

    Algal biofuels around the world represent a sustainable pathway to meet increasing demand for fuel and clean energy with reduced environmental impact. More than half of that mass consists of lipids or triacylglycerides which are also found in vegetable oils and are used to produce such advanced biofuels as biodiesel, green diesel, green gasoline and green jet fuel. Algal remediation technology ...

  • Comparative Sensitivity of Freshwater Algae to Atrazine

    Widespread use of environmentally persistent herbicides has led to increasing concern over their impact on aquatic ecosystems and nontarget organisms. The triazine herbicide atrazine (6-chloro-N-ethyl-N-[1-methylethyl]-1,3,5-triazine-2,4-diamine) remains one of the most heavily used pesticides worldwide, and was the second most commonly used convencional pesticide in the U.S. agricultural market ...

  • Moral drought: The ethics of water use

    Water has been called the berth of life as it performs basic ecological functions in every environment. Many relevant water properties are not discernible to the human senses: microbes are invisible; colour and taste often give little indication of water composition or potability. For this reason, technological deficiencies in water management are often responsible for disease, mortality and ...
