This study was to isolate, screen, and identify microorganisms from fermented food Red Oncom and Tempeh Gembus that can produce fibrinolytic proteases. Forthy-three isolates showed proteolytic activities on skim milk agar, while thirthy-eight of them showed fibrinolytic activities both on a fibrin plate and a fibrinogen zymography. The isolates that showed activity in fibrin plate and fibrinoge...

How diversity influences the stability of a community function is a major question in ecology. However, only limited empirical investigations of the diversity-stability relationship in soil microbial communities have been undertaken, despite the fundamental role of microbial communities in driving carbon and nutrient cycling in terrestrial ecosystems. In this study, we conducted a microcosm exp...

Considering the extensive functional redundancy in microbial communities and great difficulty in elucidating it based on taxonomic structure, studies on the biogeography of soil microbial activity at large spatial scale are as important as microbial community structure. Eighty-four soil samples were collected across a region from south to north China (about 1,000 km) to address the questions if...

Investigating microbial metabolic characteristics and soil organic carbon (SOC) within aggregates and their relationships under conservation tillage may be useful in revealing the mechanism of SOC sequestration in conservation tillage systems. However, limited studies have been conducted to investigate the relationship between SOC and microbial metabolic characteristics within aggregate fractio...

We studied microbial communities in two paddy soils, which did not receive nitrogen fertilization and were distinguished by the soil properties. The two microbial communities differed in the relative abundance of gram-negative bacteria and total microbial biomass. Variability in microbial communities between the two fields was related to the levels of phosphorus and soil moisture. Redundancy an...

If changes in the composition of the soil microbial community alter the physiological capacity of the community then such changes may have ecosystem consequences. We examined the relationships among community composition (PLFA), microbial biomass (CFDE), substrate utilization profiles (BIOLOG), lignocellulose degrading enzyme activities (b-glucosidase, cellobiohydrolase, b-xylosidase, phenol ox...

this study assessed the chemical and microbial contents in the water of public swimming pools in akwa ibom state, nigeria. a total of 16 public pools were selected through probability sampling from the 32 pools that existed in the five urban areas of akwa ibom state. water samples were collected from the sampled pools and tested in the laboratory for chemical and microbial contents. results sho...

Green tea kombucha made of sugar and single yeast was investigated for its antimicrobial activity and composition changes during fermentation. Individual and total tea polyphenols, caffeine, sucrose, reducing sugar, total sugar, pH, acetic acid and total acids, ethanol concentration, superoxide dismutase and hexokinase activities, yeast yield and antimicrobial activity were measured systematica...
