The Gram-negative bacterium Klebsiella planticola represents an interesting host organism for the production of biotechnological products. Microbial processes – especially those of aerobic cultivation – lead to the generation of considerable amounts of biomass, thus lowering the product yield. These are the reasons for studying methods for the recycling of biomass from K. planticola. It will be...

The usage amount of medicinal plant rapidly increased along with the development of traditional Chinese medicine industry. The higher market demand and the shortage of wild herbal resources enforce us to carry out large-scale introduction and cultivation. Herbal cultivation can ease current contradiction between medicinal resources supply and demand while they bring new problems such as pestici...

Soil cultivation is commonly used to manage organic matter (OM) accumulation in golf course putting greens. Our objectives were to determine: (i) if hollow-tine cultivation is more effective than solidtine cultivation at managing OM and water infiltration, (ii) if venting methods are effective at managing OM and water infiltration, and (iii) if venting alters or interacts with effects of earlyo...

During the sudden decrease in RNA synthesis in Streptomyces aureofaciens, i.e. around the 6th hour of cultivation, synthesis of adenosine and guanosine tetraphosphates and pentaphosphates begins. The synthesis of these nucleotides is highest during the onset of chlortetracycline production, around the 20th hour of cultivation and continues. During this phase of growth of S. aureofaciens, RNA an...

Levels of opium poppy cultivation in Afghanistan’s provinces and districts rise and fall depending on a range of factors that are not well understood. Declines in cultivation are often attributed to the political commitment of the provincial and local authorities and the role of information campaigns, while the underlying power and economic dynamics that drive these changes receive little atten...

This paper takes a comparative approach to early farming, arguing that bioarchaeological work on Neolithic Europe can inform understanding of earlier cultivation and herding in the Near East, where the ‘package’ of crops and livestock emerged in the PPNB period. Evidence for intensive cultivation (‘garden agriculture’) integrated with small-scale herding is outlined for south-east and central E...

We show that refugees can play positive roles in receiving economies by looking at the partition of India. We use an instrumental variables (IV) strategy to show that migrants played a major part in India’s take-up of jute cultivation. Our estimates suggest that migrants fully explain post-partition jute cultivation. Consistent with migrants bringing jute-specific skills with them, we find that...

Considering the drastic changes in primate habitats, we must search for management strategies to maintain primate populations in the wild. In the present study, a group of howler monkeys Alouatta palliata was followed after being translocated to a 90 ha tropical forest used for understory palm Chamaedorea elegans cultivation. The group’s behavior was recorded in the new environment. There was n...

turmeric is an important herb used as medicines, turmeric is an important herb used as medicine, condiment and cosmetic. its main active compounds are curcuminoids and essential oils. the biomass production, essential oil composition and curcuminoid content of curcuma longa are known to be dependent on the growth and development conditions of rhizome. iran is a major importer of turmeric in the...

Grown in Jamaica since the days of slavery, food yams are major staples in local diets and a significant non-traditional export crop. The cultivation system used today is the same as 300 years ago, with alleged unsustainable practices. A new cultivation system called minisett was introduced in 1985 but the adoption rate twenty four years later is extremely low. This paper analyzes the prospects...
