Summary: Open microalgal ponds are vulnerable to various biotic and abiotic stressors, leading to crashes with high economic costs. This study identified specific VOCs for early diagnosis of algal crop damage, demonstrating unique diagnostic VOCs for different damage mechanisms. Detecting these VOCs allows for targeted treatment, ultimately preventing pond crashes and enhancing algal crop yields for biofuel production.

Summary: This study demonstrated that volatile organic compounds (VOCs) produced by Pichia during baijiu fermentation have antifungal effects on Monascus purpureus, particularly 2-phenylethanol. The inhibition of fungal growth by 2-phenylethanol may be attributed to its interference with protein synthesis and DNA damage. Overall, the results suggest that Pichia plays a role in antagonizing fungal blooms in the fermentation process, potentially improving the quality of baijiu.

Summary: The aim of this study was to investigate the changes in volatile organic compounds (VOCs) in 'Golden Delicious' apples caused by mechanical damage. Direct extraction and CAR/PDMS fiber were proposed as the best methods for identifying VOCs associated with mechanical damage. The study found that the mechanical damage resulted in changes in ester compounds in the apples.

Summary: This study compared the performance of Trichoderma harzianum recombinant strains (T13 and T15) containing chimeric chit42 with Chitin Binding Domain (ChBD) and wild-type (Tw) on plant growth promotion. The recombinant strains showed increased ability to produce IAA and siderophore, as well as upregulation of genes related to biocontrol and biofertilizer activity compared to the wild-type strain. The VOCs profile of the recombinant strains revealed higher diversity and potentially more effective growth-promoting and biocontrol activity than the wild-type strain.

Summary: This investigation examined the relationship between different dry fermentation processes of coffee (aerobic, anaerobic, and CO2 modified atmosphere) and fermentation times, in relation to pH, acidity, and seven volatile marker compounds. The results showed that fermentation time had a significant effect on pH and acidity. The presence of acetic acid was positively correlated with fermentation time, while other compounds showed negative correlation. The different fermentation treatments had varying affinities with the volatile marker compounds analyzed.

Summary: This study investigated the volatile compounds and quality traits in shrimp heads stored at different temperatures, finding that the sensory scores decreased with storage time, while pH and TVB-N content increased. Specific volatile compounds were identified at different storage temperatures, and certain compounds were identified as potential markers of spoilage. The findings provide a theoretical basis for further research on quality and volatile compounds in shrimp heads for high-quality utilization.

Summary: This study investigates the use of palm oil mill effluent (POME) as a solvent to extract lignin and phenolics from oil palm empty fruit bunch fiber (OPEFBF). Results show that POME containing 5% w/w NaOH is the best solvent, producing the highest yield of lignin and phenolics. The chemical oxygen demand (COD) of the solvent increases after treatment but decreases significantly after lignin precipitation.

Summary: This study investigated and compared the metal removal efficacy of exopolymeric substances (EPS), live and dead cells of different bacteria. It was found that dead cells of Gram-positive bacteria showed better metal removal potential compared to live cells, while the opposite was observed for Gram-negative bacteria. Among the bacterial isolates, the EPS of B. cereus demonstrated the most effective biosorption of metals. EPS has the potential for metal removal, although the amount of metal removed is lower than levels removed by live and dead cells. Multi-metal systems showed lower metal removal compared to single-metal systems.

Summary: This study found that the ethyl acetate sub-fractions of Chrysanthemum morifolium dried flowers have strong inhibitory activity against Xanthine oxidase (XO), and also have a certain therapeutic effect on hyperuricemia in rats. Further research revealed that the sub-fraction may exert its anti-hyperuricemic effect through non-competitive inhibition of XO enzyme, down-regulation of XO gene expression, and increased uric acid excretion.
