Plant cells in suspension cultures tend to form aggregates. This can affect the physiology of the cells and hence the production of valuable secondary metabolites. Aggregation is also important from a process engineering point of view. In this work, the change in the size distribution of plant cell aggregates in a batch culture is studied. The growth of suspension cultures of Capsicum frutescen...

Plants have evolved a vast chemical cornucopia to support their sessile lifestyles. Man has exploited this natural resource since Neolithic times and currently plant-derived chemicals are exploited for a myriad of applications. However, plant sources of most high-value natural products (NPs) are not domesticated and therefore their production cannot be undertaken on an agricultural scale. Furth...

Plants are an important source of natural flavourings for food. Plant-derived food flavours may be based on endogenous flavour compounds or be derived from flavour precursors following enzyme action when the tissue is disrupted or during a postharvest treatment. Such flavours are usually based either on a single compound or a small group of compounds with closely related chemical structure. How...

This paper reviews the role of plant cell culture as a biotechnological tool in preserving botanical diversity higher plants while meeting growing demand commercial market for large volumes raw material. The prospects cell-based technology are discussed framework creating an economy sustainable development short and long term.

Clostridium cellulovorans produces a cellulase enzyme complex (cellulosome). In this study, we isolated two plant cell wall-degrading cellulosomal fractions from culture supernatant of C. cellulovorans and determined their subunit compositions and enzymatic activities. One of the cellulosomal fractions showed fourfold-higher plant cell wall-degrading activity than the other. Both cellulosomal f...

background: chlamydia trachomatis is the most reported bacterial sexually transmitted disease, especially among young women worldwide. aim of this study was comparison to evaluate the prevalence of chlamydia trachomatis infection in woman with tubal infertility by means of pcr and cell culture techniques. methods: fifty-one women with confirmed tfi were enrolled in this study in (avicenna infer...

The objective of this study was to establish cell suspension culture and plant regeneration via somatic embryogenesis of a Brazilian plantain, cultivar Terra Maranhão, AAB. Immature male fl owers were used as explant source for generating highly embryogenic cultures 45 days after inoculation, which were used for establishment of cell suspension culture and multiplication of secondary somatic em...

A phytostat to mass culture higher plant cells in liquid medium is described. This apparatus allowed the culture in batch, turbidostat and chemostat of 20 liters of cells. Automatic control of cell suspension growth was based on culture turbidity. Changes with time of certain cell characteristics, particularly cell respiration and phospholipid content, indicated that the test time to harvest la...
