Nannochloropsis for the bioremediation of brewery side streams and co-production of aquaculture feed and bio-Fertiliser: A comprehensive review
No full textThe brewing industry produces a large amount nutrient-rich wastewater. This review proposes a framework that
harnesses autotrophic microalgae to establish a circular brewing industry. The study focuses on Nannochloropsis
due to their high omega-3 polyunsaturated lipids and protein content, enabling the upcycling of brewery
wastewater into aquaculture feed and biofertiliser. In the proposed system, Nannochloropsis is cultivated on
brewery wastewater under mixotrophic conditions, and the resultant biomass is used as a fishmeal replacement
or biofertiliser. This approach reduces chemical and energy demands for brewery wastewater treatment, while
also alleviating aquaculture’s reliance on fishmeal derived from unsustainable wild-caught fishing and agriculture’s
dependence on carbon-intensive mineral fertilisers. A summary of the research to-date on the cultivation of
microalgae on brewery wastewater, the use of brewer’s spent grain as widely available and inexpensive carbon
for microalgal fermentation, the application of Nannochloropsis in aquaculture and bio-fertiliser, and technoeconomic
and life-cycle assessments of the proposed system are provided. A mass balance of the system suggests
that for every 1000 L of brewery wastewater that is treated, 1.0–1.4 kg of Nannochloropsis biomass can be
produced, enabling the removal of 95–100 % of N and P and 60–90 % COD reduction from the wastewater and
the direct capture of 0.7–1.3 kg of CO2, while producing 0.4–0.8 kg of lipids for aquafeed formulations and
0.6–1.0 kg of biomass residue for biofertilisers. An integrated approach that combines laboratory research with
pilot-scale validation and iterative techno-economic assessments is needed to inform optimisation and guide
scale-up

Flavonoids from Capsella bursa-pastoris and their hepatoprotective activities in vitro
No full textAbstractTwo new flavonoids (1 and 2), named 4′,7-dihydroxy-5-hydroxymethyl-8-prenylflavonoid and 4′,7-dihydroxy-5-hydroxymethyl-6,8-diprenylflavonoid, together with seven known flavonoids (3–9) were isolated from the aerial parts of Capsella bursa-pastoris (L.) Medik., Brassicaceae, for the first time. The chemical structures of the purified compounds (1–9) were identified by their spectroscopic data and references. Moreover, compounds (1–9) were evaluated for their hepatoprotective activities against d-galactosamine induced toxicity in WB-F344 cells by using a MTT colorimetric method. As a result, compounds 2, 3, 6, and 9 (10μM) exhibited moderate hepatoprotective activities
Genome-wide identification and expression analysis of the kinesin gene superfamily suggests roles in response to abiotic stress and fertility of wheat (Triticum aestivum L.)
No full textAbstract Background Kinesin is a motor for microtubule-based motility. It plays a vital role in plant growth and development. The kinesin superfamily members are known mainly from Arabidopsis. Little research about kinesin superfamily has been conducted on hexploid wheat (Triticum aestivum L.). The functions of kinesins in wheat growth and development, regulation of cell division and response to stress are still unclear. Results In this study, we identified 155 kinesin (TaKIN) genes in wheat, which were divided into 10 families and some orphan genes via phylogenetic analysis. Less gene structural differences showed that TaKIN genes had redundant functions. The conserved domains of different family members were different, and some families might have some special functional domains. We found many cis-acting elements related to hormones (GA, Auxin, SA, MeJA), cell cycle and cell division in homeopathic elements of the TaKIN genes. Collinearity analysis showed that TaKIN genes were more conservative in monocotyledons. Expression level in different tissues at different stages suggested that TaKIN family may function during the whole growth and development process in wheat. It was worth noting there were quite different at gene expression level between physiological and heritable male sterile lines during the different stages of pollen development. The differential expression patterns of some TaKIN genes between male sterile line and maintainer line might be related to wheat male sterility. Furthermore, we also found TaKIN genes were involved in response to plant hormones and abiotic stress by stress assays. Conclusions The result is useful for further exploration of the molecular mechanism of kinesin genes in wheat male sterility and provides important information concerning response to plant hormones and abiotic stress caused by kinesin genes
