A comparative study of the growth of Tetraselmis sp. in large scale fixed depth and decreasing depth raceway ponds
Das, Probir; Thaher, Mahmoud Ibrahim; Abdul Quadir, Mohammed; AbdulHakim, Mohd; Al-Jabri, Hareb Mohammed S. J.; Alghasal, Ghamza Saed H. S.... more authors ... less authors ( Elsevier Ltd , 2016 , Article)In this study, an alternative approach was proposed where excess seawater would be added only during inoculation (DD) rather than daily addition (FD). Growth and metabolite contents of Tetraselmis sp. weren't affected for ... -
Biocrude oil production from a self-settling marine cyanobacterium, Chroococcidiopsis sp., using a biorefinery approach
Das, Probir; Khan, Shoyeb; AbdulQuadir, Mohammed; Thaher, Mahmoud Ibrahim; Hawari, Alaa H.; Alshamri, Noora; AlGhasal, Ghamza; Al-Jabri, Hareb M.J.... more authors ... less authors ( Elsevier , 2023 , Article)Although the whole microalgal biomass is typically used as a feedstock for hydrothermal liquefaction (HTL), the conversion of a primary metabolite (i.e., carbohydrate) to biocrude is very low. In this study, a self-settling ... -
Determination of Optimum Iron Requirement for Production of Microalgae Biomass as Biofuel Feedstock
Das, Probir; Thaher, Mahmoud Ibrahim; Quadir, Mohammed Abdul; Aljabri, Hareb Mohammed S.J. ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Microalgae biomass is considered as one of the promising alternative feedstock for biofuel production. The biomass productivity of some of the microalgae can exceed an order of magnitude compared to any other terrestrial ... -
Efficient extraction of lipids from microalgal biomass for the production of biofuels using low-cost protic ionic solvents
Talhami, Mohammed; Mussa, Afnan A.; Thaher, Mahmoud Ibrahim; Das, Probir; Abouelela, Aida Rafat; Hawari, Alaa H.... more authors ... less authors ( Elsevier , 2023 , Article)The valorization of lipids available in microalgal biomass supports the indispensable transition from fossil fuels to renewable energy systems such as biofuels. Ionic liquids have been long investigated for the effective ... -

Alateyah, Nouralhuda; Ahmad, Salma M. S.; Gupta, Ishita; Fouzat, Arij; Thaher, Mahmoud Ibrahim; Das, Probir; Al Moustafa, Ala-Eddin; Ouhtit, Allal... more authors ... less authors ( Frontiers Media S.A. , 2022 , Article)Breast cancer (BC) is the most common malignant cancer in females worldwide. Drug resistance, toxicity, and the failure of current therapies to completely cure BC has challenged conventional medicine. Consequently, ... -
Microalgae harvesting by pH adjusted coagulation-flocculation, recycling of the coagulant and the growth media
Das, Probir; Thaher, Mahmoud Ibrahim; Abdul Quadir, Mohammed; Hakim, MohdAbdul; Al-Jabri, Hareb Mohammed S.J.; Alghasal, Ghamza Saed H. S.... more authors ... less authors ( Elsevier Ltd , 2016 , Article)Coagulation-flocculation can be considered as one of the least energy intensive microalgae biomass harvesting processes. However, cost of the coagulant and biomass contamination are two critical issues that need to be ... -
Microalgal bioremediation of brackish aquaculture wastewater
Kashem, Abdurahman Hafez Mohammed; Das, Probir; AbdulQuadir, Mohammad; Khan, Shoyeb; Thaher, Mahmoud Ibrahim; Alghasal, Ghamza; Hawari, Alaa H.; Al-Jabri, Hareb... more authors ... less authors ( Elsevier , 2023 , Article)Rapid aquaculture industry development contributed to a major increase in aquaculture wastewater generation. In the context of a circular economy, aquaculture wastewater treatment should simultaneously recover nutrients ... -
Optimization of iron dosage for microalgal biomass production as a feedstock for biofuel
Das, Probir; Thaher, Mahmoud Ibrahim; Abdul Hakim, Mohammed Abdul Quadir Mohd; Al-Jabri, Hareb Mohammed S.J.; Alghasal, Ghamza Saed H.S.
