Abstract: Co-cultivation of microalgae and microbes for pollutant removal from sewage is considered as an effective wastewater treatment method. The aim of this study is to screen the optimal photoperiod, light intensity and microalgae co-cultivation method for simultaneously removing nutrients in biogas slurry and capturing CO₂ in biogas. The microalgae-fungi pellets are deemed to be a viable ...
BACKGROUND Microalgae, with the ability to mitigate CO(2) emission and produce carbohydrates and lipids, are considered one of the most promising resources for producing bioenergy. Recently, we discovered that autophagy plays a critical role in the metabolism of photosynthetic system and lipids production. So far, more than 30-autophagy related (ATG) genes in all subtypes of autophagy have been...
Heavy metal pollution in aquatic ecosystems affects microalgae and zooplankton, alters the biomass and abundance of species, and promotes interspecies relationships to the predominance of less sensitive species. In this study, the effect of short-term stress of different concentrations of cadmium heavy metal on Chlorella sp. growth and some biochemical parameters have been investigated. Microal...

Phycoremediation is the process of employing algae for removing excess nutrient load from wastewater and subsequently diminish the pollution load. It is an alternative technology of treating sewage wastewater compare to conventional treatment process in economical and sustainable way. Therefore, in the present investigation we had made an effort to phycoremediate the IARI’s sewage wastewater wi...
For overcoming the long period of seed cultured photoautotrophically and inadequate cell supply for the inoculation of microalgae photoautotrophic cultivation, a model for the photoautotrophic culture of three Chlorella species with heterotrophic cells as seed was investigated. The model can not only take advantages of rapid cell growth in heterotrophic process for preparation of cells as seed ...
regarding increasing rate of drug resistance among microbial pathogens, a global search to find new antimicrobial agents from natural compounds with fewer side effects has been considered by many researchers worldwide. bioactive compounds with good antimicrobial activity have been isolated from different algae and cyanobacteria. the current study was performed to determine antimicrobial potenti...
Chlorella sp. microalgae is a potential source of antioxidants and natural bioactive compounds used in the food and pharmaceutical industries. In this study, a subcritical water (SW) technology was applied to determine the phenolic content and antioxidant activity of Chlorella sp. This study focused on maximizing the recovery of Chlorella sp. phenolic content and antioxidant activity measured b...
Nitrogen and phosphorus present in sewage can be used for microalgae growth, possibiliting cost reduction in the production of microalgae at the same time that it decreases the eutrophication potential of the effluent. This research aimed at monitoring the native community of microalgae and coliform bacteria in a secondary effluent from anaerobic municipal sewage treatment. Two treatments (aera...
wastewater contains many organic and inorganic contaminants that can cause serious damage to the environment and health of people, therefore, they have to be eliminated before being downloaded into sensitive areas. different methods of wastewater purification have been used for contaminants removal. however, they present some technical and economic limitations. thus, new methods of nutrients re...
