Microalgae have the potential to grow in nutrient-rich environments and ability accumulate nutrients from wastewater. The malting wastewater are ideal for microalgae cultivation. However, there is limited published work on growth characteristics of freshwater grown effluent. This study examined diluted effluent green algae Chlorella sp. Chlamydomonas isolated northern Ontario subsequent biomass...
Two cold-tolerant microalgae, Chlorella vulgaris and Scenedesmus sp., were grown at 22 5 °C. At the lower temperature, microalgae showed substantial biochemical morphological changes. The soluble sugar profile in response to low-temperature cultivation was very different two strains. C. increased both sucrose raffinose family oligosaccharides (RFOs) content °C while sp. drastically reduced cont...
The aim of this study was to analyze the population growth cladoceran Moina minuta using three food sources: Chlorella sp., Saccharomyces cerevisiae and fish broth. experimental design completely randomized with 3 treatments replicates, being experiment carried out for 12 days M. fed sp. showed maximum density 11.27 org. mL-1 on ninth day experiment, while organisms S. broth reached 4.92 3.67 e...
Alfred Koch has given considerable attention to the subject of nitrogen fixation by bacteria as resulting from their symbiosis with alga~. Many others have also investigated various features of this problem. In spite of all this there are numerous questions which remain unsolved. The use of soil cultures for such studies is objectionable on account of the soil's complexity, its variety of flora...
The freshwater microalgae Chlorella sp. and Vulgaris were cultured in a laboratory-scale photobioreactor their growth kinetics total lipid production evaluated. These species grown modified Conway medium, with an 8:16 photoperiod mechanical air ventilation. evaluation time was twenty days, the cell density determined daily using Neubauer chamber by optical spectrophotometry at 685 nm. rate perc...
تولید پساب های ناشی از فعالیت های کشاورزی و صنعتی، باعث برهم خوردن کیفیت آب ها شده است. فسفات و نیترات موجود در این پساب ها، مزاحمت های محیط زیستی بسیاری ایجاد می نمایند. کاهش مقدار مواد محلول باقیمانده در فاضلاب پس از طی فرآیند تصفیه و نیز استفاده از روش های بیولوژیکی به جای روش های شیمیایی موجود، دلیل اصلی انجام این تحقیق بوده است. صدف Anodonta cygnea در میان صدف های آب شیرین، یکی از انواع مه...
Tofu liquid waste that contains high levels of COD (Chemical Oxygen Demand), BOD (Biological and TSS (Total Suspended Solid) is usually discharged directly into the waters, causing a foul odor in community drainage contaminating rivers. This study aims to determine potential Chlorella sp as bioremediation agent tofu wastewater. type research uses literature review method. The stages collection ...
مقدمه: سیلرهای mta fillapex و iroot sp دو سیلر جدید هستند که ویژگیهای بسیار مشابه با mta دارند. هدف از این مطالعه مقایسه سیل اپیکال کانالهای پر شده با این دو سیلر با سیلر ah-plusبود. مواد و روشها: 72 دندان پرمولر تک کانال جهت انجام مطالعه انتخاب شدند. کانالها به روش step back آمادهسازی شدند. 6 نمونه جهت کنترل منفی و 6 نمونه برای کنترل مثبت در نظر گرفته شدند. بقیه نمونهها در سه گروه 20 تای...
The traditional green algal genus Chlorella, which comprised coccoid algae surrounded by a smooth cell wall and reproducing solely by autosporulation, has proved to be polyphyletic and extremely diverse in phylogenetic terms. We studied a new subaerial Chlorella-like strain CAUP H7901 and morphological, ultrastructural, and molecular phylogenetic investigations indicated that it represents a ne...
