Microbial Biomass and Activity in Lead-Contaminated Soil [PDF]

Applied and Environmental Microbiology, 1999
ABSTRACT Microbial community diversity, potential microbial activity, and metal resistance were determined in three soils whose lead contents ranged from 0.00039 to 48 mmol of Pb kg of soil −1 . Biomass levels were directly related to lead content. A molecular analysis of 16S rRNAs suggested that each soil

Atmospheric ammonia concentration modulates soil enzyme and microbial activity in an oak forest affecting soil microbial biomass

, 2018
The present work was carried out to assess the effect of atmospheric ammonia (NH3) on soil physicochemical properties, soil enzymatic activities (β-glucosidase -β-GLU-, nitrate reductase –NR-, urease –UR-, protease –PRO-,acid phosphatase –PHO ...

Effects of metal toxicity on the size of the soil microbial biomass

, 1984
The amount of soil microbial biomass was measured by the chloroform fumigation technique on agricultural soils which had been previously treated with different bulky organic manures.

Hydrology drives facilitative and competitive strategies in freshwater macrophyte and microbial communities

Ecosphere
Pulses of resource availability along environmental gradients can filter the local and regional distribution of macrophyte and microbial mat communities in wetlands. Wetlands that experience short hydroperiods (i.e.,

Microwave-assisted acid and alkali pretreatment of Napier grass for enhanced biohydrogen production and integrated biorefinery potential

Chemical Engineering Journal Advances
Napier grass, a promising lignocellulosic energy crop, presents a complex composition that limits its bioconversion into fermentable products. To address this challenge, we applied microwave (MW) pretreatment assisted by acid and alkali, using varying ...

Short communication: The persistent influence of host lineage on the gut microbiomes of black soldier fly and yellow mealworm

Animal
Production insects such as the black soldier fly (BSF) and yellow mealworm (YM) are increasingly recognised as sustainable protein sources, and selective breeding of genetically distinct lines offers opportunities to improve production efficiency ...

Adenosine triphosphate of the soil microbial biomass

, 1979
In a heterogeneous group of 11 soils there was a linear relationship (r = 0.98) between ATP content and biomass C content, as measured by the fumigation technique.

Cadmium and zinc toxicity to soil microbial biomass and activity

, 2002
The effects of sewage sludge selectively enriched with zinc at the maximum perrniued level and cadmium at concentration four times the current EU limits on microbial biomass and activity were tested using soils under different management in a ...
