Syntrophic microbial system for ex-situ degradation of paddy straw at low temperature under controlled and natural environment
Journal Title: Journal of Applied Biology & Biotechnology - Year 2016, Vol 4, Issue 2
Abstract
The syntrophic microbial application for lignocellulosic biodegradation and subsequent transformation into compost provides an alternative strategy against burning and disposing post harvested agricultural biomass which is of vital importance in agriculture used as compost. Biodegradation process is hindered during winter season, as the microorganisms involved in lignocellulose biodegradation slows down their metabolism due to unfavourable growth conditions at low temperatures. In order to intensify the composting process at low temperature, psychrotrophic microbes were isolated and characterized for lignocellulosic hydrolytic potential specifically at low temperatures. Among the isolated microbes, four efficient lignocellulolytic psychrotrophic microbes (Eupenicillium crustaceum, Paceliomyces sp., Bacillus atropheus and Bacillus sp.) and commercial fungal consortia (Aspergillus awamori, Aspergillus nidulans, Trichoderma viride and Phanerochaete chrysosporium) were used in present study. It was found that psychrotrophic microbes along with the commercial fungal consortium enhanced the composting process at low temperature. These psychrotrophic and mesophilic microbial consortium can be used for degradation of agri-residues and conversion to a value added product like compost, which helps in enhancing soil fertility and decreasing environmental pollution caused by burning of agrowastes. This is the first report for biodegradation of paddy straw by psychrotrophic microbes at low temperatures.
Modulation of some biochemical complications arising from alloxan-induced diabetic conditions in rats treated with Senna occidentalis leaf extract
The present study was designed to evaluate the effects of Senna occidentalis in alloxan-induced diabetic and its complications in Wistar rats. Thirty male Wistar rats with body weight ranging from 180–250 g were selected...
Metabolic syndrome susceptibility of suckling male and female rats given oral administration of natural honey compared with cane syrup
The acute effects of natural honey (NH) and cane syrup (golden syrup, GS) on metabolism in 89 (10-day old) suckling Sprague Dawley rats were investigated. Low dose group fed 10mls/kg of either NH or GS; high dose group g...
Practiced Gram negative bacteria from dyeing industry effluents snub metal toxicity to survive
Isolation and characterization of metal-tolerant bacteria from dyeing industry effluent was the prime drive of the present investigation. Results yielded during screening and isolation, noted the dominance of bacteria ve...
Bioactive potential of Diadema sp. from the South East Coast of Mauritius
As a consequence of the alarming rise in antimicrobial resistance, this study aimed at evaluating the bioactive potential of sea urchin extract, Diadema sp. Two different tissues; shells and gonads were used and two dryi...
Control of Fusarium oxysporum infection in transgenic tobacco carrying oxalate descarboxilase gene
Fusarium oxysporum is a widespread necrotrophic plant pathogen. Its infection affects several crop plants such as potato, tomato, cotton, banana, coffee, strawberry and sugarcane. The fungus produces oxalic acid, which t...
