Article
The applicability of extremophilic amylases in hydrolyzing food waste for bioethanol production has not been investigated much. The current study aims to extract amylases from halophilic bacteria isolated from a hypersaline mat and to use them for the saccharification of food waste to produce bioethanol. Nine halophilic bacteria belonging to the ge...

A major obstacle of bioethanol production is finding a renewable and cheap feedstock, which still needs to be addressed. This work focuses on comparing bioethanol production from buttonwood and date palm leaves. Furthermore, cellulase activities were compared from 4 newly isolated cellulase producing Bacillus spp. and optimal temperature, pH and me...

Biodiesel is considered the most convenient biofuel, due to its direct use in existing combustion engines; however, its production is not economically optimal due to processes that utilize costly substrates, require high energy expenditure or achieve low biodiesel yields. We used primary sewage sludge for the production of biodiesel and compared yi...

Desert streams occur in abundance in the mountain regions of the Arabian Peninsula, where massive areas are covered by phototrophic microbial mats. In this study, 11 different phototrophic microbial mats were screened for their carbohydrate and lipid contents and their ability to produce methane, and mats with potential were further used for biofue...
Article
Fecal waste is an environmental burden that requires proper disposal, which ultimately becomes also an economic burden. Because fecal waste is nutrient-rich and contains a diverse methanogenic community, it has been utilized to produce biomethane via anaerobic digestion. Carbohydrates and lipids in fecal waste could reach up to 50% of the dry weigh...

Cyanobacteria hold significant potential as industrial biotechnology (IB) platforms for the production of a wide variety of bio-products ranging from biofuels such as hydrogen, alcohols and isoprenoids, to high-value bioactive and recombinant proteins. Underpinning this technology, are the recent advances in cyanobacterial "omics" research, the dev...

A lot of research has been performed on cyanobacteria and microalgae with the aim to produce numerous biotechnological products. However, native strains have a few shortcomings, like limitations in cultivation, harvesting and product extraction, which prevents reaching optimal production value at lowest costs. Such limitations require the intervent...
