This volume contains the proceedings of the international conference “Cultural developments and technological innovations in first millennium BC/AD West Africa” held in Ouagadougou, Burkina Faso, in March 2008, with participants from eleven countries and three continents. The rationale behind the meeting was the conviction that the first millennium before and after the beginning of the Common Era, like no other period before, encompasses the origins of developments that are directly related to the modern world – particularly in Africa. Current archaeological research in West Africa has been providing an increasing amount of relevant evidence on this period, including a series of significant developments that had critical impacts on human ways of life in subsequent times. The papers of the present volume deal with different aspects of these developments and contribute towards the understanding of the unique cultural diversity of this part of the African continent.

Micro and Macroparticle enhanced cultivation of filamentous Lentzea aerocolonigenes for increased rebeccamycin production

The filamentous actinomycete Lentzea aerocolonigenes produces the antitumor antibiotic rebeccamycin. However, the complex morphology of actinomycetes leads to challenges during the cultivation often accompanied by low product titers. In the recent past, the to date low rebeccamycin titers were increased by particle addition to cultivations of L. aerocolonigenes. In this thesis the addition of micro-, macro- and adsorbent particles to cultivations of L. aerocolonigenes were investigated in more detail. Furthermore, the scale-up to a bubble-free bioreactor was conducted. The addition of glass microparticles (x50 = 7.9 μm, 10 g L-1) to shake flask cultivations increased the rebeccamycin titer up to 3.6-fold compared to an unsupplemented approach. Pellet slices showed the incorporation of microparticles. With different surface modifications of the microparticles, specific incorporation patterns of the microparticles appeared. The incorporation of microparticles causes looser and smaller pellets allowing an increased nutrient and oxygen supply in the pellet core. With addition of larger (glass) macroparticles (ø = 0.2 – 2.1 mm, 100 g L-1) mechanical stress was induced on the biopellets. The additional supplementation of 5 g L-1 soy lecithin and glass beads (ø = 969 μm, 100 g L-1) resulted in a rebeccamycin titer of 388 mg L-1, one of the highest rebeccamycin titers ever achieved. For the scale-up of L. aerocolonigenes cultivations a bubble-free membrane aeration system was developed. The tubular membrane aeration system can additionally be pressurized to increase the oxygen transfer. First cultivations of L. aerocolonigenes successfully provided 18 mg L-1 rebeccamycin, a concentration similar to that of unsupplemented shake flask cultivations. XAD adsorbent particles were added to cultivations to facilitate rebeccamycin recovery. However, the XAD particles additionally increased the rebeccamycin titer which was likely to be caused by the adsorption of the rebeccamycin precursor tryptophan to the resins which in turn directly transferred the tryptophan to the microorganism.

The book is the volume of “The History of Science and Technology in the Spring and Autumn Period and the Warring States Period” among a series of books of “Deep into China Histories”. The earliest known written records of the history of China date from as early as 1250 BC, from the Shang dynasty (c. 1600–1046 BC) and the Bamboo Annals (296 BC) describe a Xia dynasty (c. 2070–1600 BC) before the Shang, but no writing is known from the period The Shang ruled in the Yellow River valley, which is commonly held to be the cradle of Chinese civilization. However, Neolithic civilizations originated at various cultural centers along both the Yellow River and Yangtze River. These Yellow River and Yangtze civilizations arose millennia before the Shang. With thousands of years of continuous history, China is one of the world's oldest civilizations, and is regarded as one of the cradles of civilization.The Zhou dynasty (1046–256 BC) supplanted the Shang and introduced the concept of the Mandate of Heaven to justify their rule. The central Zhou government began to weaken due to external and internal pressures in the 8th century BC, and the country eventually splintered into smaller states during the Spring and Autumn period. These states became independent and warred with one another in the following Warring States period. Much of traditional Chinese culture, literature and philosophy first developed during those troubled times.In 221 BC Qin Shi Huang conquered the various warring states and created for himself the title of Huangdi or "emperor" of the Qin, marking the beginning of imperial China. However, the oppressive government fell soon after his death, and was supplanted by the longer-lived Han dynasty (206 BC – 220 AD). Successive dynasties developed bureaucratic systems that enabled the emperor to control vast territories directly. In the 21 centuries from 206 BC until AD 1912, routine administrative tasks were handled by a special elite of scholar-officials. Young men, well-versed in calligraphy, history, literature, and philosophy, were carefully selected through difficult government examinations. China's last dynasty was the Qing (1644–1912), which was replaced by the Republic of China in 1912, and in the mainland by the People's Republic of China in 1949.Chinese history has alternated between periods of political unity and peace, and periods of war and failed statehood – the most recent being the Chinese Civil War (1927–1949). China was occasionally dominated by steppe peoples, most of whom were eventually assimilated into the Han Chinese culture and population. Between eras of multiple kingdoms and warlordism, Chinese dynasties have ruled parts or all of China; in some eras control stretched as far as Xinjiang and Tibet, as at present. Traditional culture, and influences from other parts of Asia and the Western world (carried by waves of immigration, cultural assimilation, expansion, and foreign contact), form the basis of the modern culture of China.
