Diverse Microbial Community

Studies on stressor responses are often performed in controlled laboratory settings. The microbial communities in laboratory setting often differ from the natural environment, which could ultimately be reflected in different stress responses. In this study, we investigated how stressor responses differed between laboratory and natural conditions in Daphnia magna when exposed to single or multiple stressors. Daphnia individuals were exposed to the toxic cyanobacterium Microcystis aeruginosa and a fungal infection, Aspergillus aculeatus like type. Three genotypes were included to investigate genotype-specific responses. Survival, reproduction and body size were monitored for three weeks and gut microbial communities were sampled and characterized at the end of the experiment. Our study shows that natural environments have a more diverse microbial community compared with laboratory conditions, which was ultimately reflected in the gut microbiomes after inoculation. Stressor responses in Daphnia were affected by their bacterial environment for survival, but not for fecundity and body size. Fecuntiy and body size did show a main stressor effect, which could possibly be linked with stessor-specific microbiomes (for Microcystis and the combined stressor treatment). In addition, genotype-specific responses were detected for survival and fecundity, which could be linked with the selective capabilities of the Daphnia genotypes to select beneficial or neutral microbial stains from the environment.

Tap Water Quality

Assessment of the quality of tap water at Kuantan area of Pahang, Malaysia was investigated. The parameters analyzed were total coliform, Escherichia coli, pH, total hardness, sulfate, and selected heavy metal based on drinking water quality standard Malaysia and WHO. The results showed that the fungi in the tap water in Kuantan area in different concentrations were Aspergillus sp., Rhodotorula mucilaginosa, Penicillium citrinum, Cladosporium cladosporioides, Cerrena sp., Aspergillus aculeatus, A. flavus, Cryptococcus sp., Cladosporium perangustum, Purpureocillium lilacinum and Candida catenulata. The residual free chlorine varied from 0.05 to 1.97 mg/l.

Abstract A description is provided for Aspergillus aculeatus. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Not a common species, but it has been isolated from soils and organic debris (CABI BIOSCIENCE, 1999). DISEASES: Causes postharvest dry rot of tomatoes (FAJOLA, 1979). GEOGRAPHIC DISTRIBUTION: World-wide, but with a preference for tropical and subtropical climates.
