Greener and cleaner: Yeast-green algae mix improves water treatment

Greener and cleaner: Yeast-green algae mix improves water treatment

Bakeries and wineries can’t do without yeast, but they have no need for green algae. Wastewater treatment facilities, however, might just want to have these microorganisms team up. Osaka Metropolitan University researchers have discovered that these simple organisms form the best combination in terms of boosting wastewater treatment efficiency.

The active sludge method of wastewater treatment requires electricity to ensure the flow of oxygen that feeds bacteria and other organisms that process the water. Adding microalgae to conduct photosynthesis, which produces oxygen, improves energy-efficiency, but low carbon dioxide levels hinder their growth. Enter the yeast Saccharomyces cerevisiae, which produces carbon dioxide.

Associate Professor Ryosuke Yamada of the Graduate School of Engineering led the group in investigating which combination of these types of microorganisms would provide the highest efficiency in wastewater treatment. Reported for the first time to the researchers’ knowledge, the group found that the combination of the green algae Chlamydomonas reinhardtii and yeast had the best efficiency. Notably, the combination enhanced the green algae’s ability to absorb ammonium and phosphate ions.

“The green algae and yeast are highly safe for humans, especially considering that treated wastewater is discharged into the environment,” Professor Yamada explained. “These microorganisms can also accumulate useful compounds such as polysaccharides, fats, and oils in their cells, and be used as microbial fertilizers, so it is possible to expect useful compounds to be produced at the same time as the wastewater is being treated.”

The findings were published in Applied Microbiology and Biotechnology.

Acquired immune thrombotic thrombocytopenic purpura (TTP) associated with inactivated COVID-19 vaccine CoronaVac

Acquired immune thrombotic thrombocytopenic purpura (TTP) associated with inactivated COVID-19 vaccine CoronaVac
2024-11-08
The COVID-19 pandemic has prompted the rapid development and administration of various vaccines worldwide, with some reports linking these vaccines to immune thrombotic thrombocytopenic purpura (TTP). This report presents two cases of TTP occurring after the administration of the inactivated vaccine CoronaVac from Sinovac Biotech, highlighting the potential association between this type of vaccine and TTP. The article also provides an analysis of TTP incidence in the Nanjing area of China, suggesting a possible correlation between COVID-19 vaccination and the occurrence of TTP.   The first case details a 23-year-old female who developed symptoms of TTP three days ...

CIDEC as a novel player in abdominal aortic aneurysm formation

CIDEC as a novel player in abdominal aortic aneurysm formation
2024-11-08
Abdominal aortic aneurysm (AAA) is a degenerative lesion characterized by structural disruption of the abdominal aortic wall and progressive dilatation into a pulsatile mass. AAA is strongly associated with obesity, partly due to abnormal dilatation of perivascular adipose tissue (PVAT) in the abdomen, however, direct evidence is still lacking.   Cell death-inducing DNA fragmentation factor-like effector C (CIDEC), also known as fat-specific protein 27 (FSP27) in rodents, is a lipid droplet (LD)-associated protein that plays an important role in lipid storage. It has been reported that CIDEC/FSP27 promotes the growth of LDs by mediating the exchange and transfer of lipids ...

Artificial intelligence: a double-edged sword for the environment?

Artificial intelligence: a double-edged sword for the environment?
2024-11-08
As artificial intelligence (AI) technology progresses, the energy demands of training complex models have surged, raising widespread concerns about associated carbon emissions. This rapid growth is fueled by global demand across industries and academia, leading to exponential increases in computing power that carry significant environmental consequences. Given these challenges, in-depth research is essential to fully understand AI's carbon footprint and develop strategies for mitigating its environmental impact. In a view (DOI: 10.1007/s11783-024-1918-y) by ...

Current test accommodations for students with blindness do not fully address their needs

2024-11-08
Tsukuba, Japan—Students often appear for high-stakes tests that hold significant weight in determining their futures. One such examination, the Common Test for University Admissions, currently allows examinees using braille an extended examination time of 1.5 times the standard duration. However, with the recent increase in complex questions and questions involving charts and diagrams in such tests, it is necessary to review whether the current accommodations remain adequate. The researchers assessed the validity of the current time extension for examination questions containing complex tables by measuring the time required to read the text and complex tables. The results showed that ...

Wide-incident-angle wideband radio-wave absorbers boost 5G and beyond 5G applications

Wide-incident-angle wideband radio-wave absorbers boost 5G and beyond 5G applications
2024-11-08
5G wireless communication services have rapidly expanded worldwide, leveraging millimeter-wave (mmW) frequencies in the 24 GHz to 71 GHz range (referred to as frequency range 2, or FR2). Looking ahead, Beyond 5G and 6G services, projected to offer ultra-fast connectivity exceeding 100 Gbit/s, are expected to be introduced in the 2030s. Frequencies in the 150-GHz to 300-GHz range are being considered as potential candidates for these future networks. However, critical components such as radio-wave absorbers, essential for packaging and modularization, still need to be developed. These absorbers play a key role in reducing ...

A graph transformer with boundary-aware attention for semantic segmentation

A graph transformer with boundary-aware attention for semantic segmentation
2024-11-08
The transformer-based semantic segmentation approaches, which divide the image into different regions by sliding windows and model the relation inside each window, have achieved outstanding success. However, since the relation modeling between windows was not the primary emphasis of previous work, it was not fully utilized. To solve the problems, a research team led by Zizhang Wu published their new research on 15 October 2024 in Frontiers of Computer Science co-published by Higher Education Press and Springer ...

First-of-its-kind analysis of U.S. national data reveals significant disparities in individual well-being as measured by lifespan, education, and income

2024-11-08
First-of-its-kind analysis of US national data reveals significant disparities in individual well-being as measured by lifespan, education, and income.  White males make up largest share of the group with lowest well-being while American Indian and Alaska Native individuals, and Black males, face the most significant challenges to overall well-being.   Populations at the lowest levels of well-being across the US are especially concentrated in the Deep South, Appalachia, and the Rust Belt.  The ...

Exercise programs help cut new mums’ ‘baby blues’ severity and major depression risk

2024-11-08
Exercise-only programmes help cut the severity of the ‘baby blues’ and the risk of major clinical depression in new mums, finds a pooled data analysis of the available evidence, published in the British Journal of Sports Medicine. But at least 80 weekly minutes of moderate intensity exercise, such as brisk walking, water aerobics, stationary cycling, and resistance training with bands, weights, or body weight are needed to achieve the effects, the findings show. Maternal depression and anxiety are relatively common after giving birth and associated with reduced self-care and compromised infant caregiving and bonding, ...

Gut microbiome changes linked to onset of clinically evident rheumatoid arthritis

2024-11-08
Changes in the make-up of the gut microbiome are linked to the onset of clinically evident rheumatoid arthritis in those at risk of the disease because of genetic, environmental, or immunological factors, suggests research published online in the Annals of the Rheumatic Diseases.   It’s not clear if this instability is a cause or consequence of disease development, emphasise the researchers, but the findings might nevertheless help to identify those at risk as well as paving the way for preventive and personalised treatment strategies, they suggest. Previously published research consistently shows an unfavourable imbalance in ...
