Nutritional demands and metabolic characteristics of the DSIR-HA-1179 insect cell line during growth and infection with the Oryctes nudivirus. In Vitro Cell Dev Biol Anim 2017; 53:908-921.

Abstract
The DSIR-HA-1179 coleopteran cell line has been identified as a susceptible and permissive host for the in vitro replication of the Oryctes nudivirus, which can be used as a biopesticide against the coconut rhinoceros beetle, pest of palms. The major challenge to in vitro large-scale Oryctes nudivirus production is ensuring process economy. This rests, among other requisites, on the use of low-cost culture media tailored to the nutritional and metabolic needs of the cell line, both in uninfected and infected cultures. The aim of the present study was to characterize the nutritional demands and the metabolic characteristics of the DSIR-HA-1179 cell line during growth and subsequent infection with Oryctes nudivirus in the TC-100 culture medium. Serum-supplementation of the culture medium was found to be critical for cell growth, and addition of 10% fetal bovine serum v/v led to a maximum viable cell density (16.8 × 105 cells ml-1) with a population doubling time of 4.2 d. Nutritional and metabolic characterization of the cell line revealed a trend of glucose and glutamine consumption but minimal uptake of other amino acids, negligible production of lactate and ammonia, and the accumulation of alanine, both before and after infection. The monitoring of virus production kinetics showed that the TC-100 culture medium was nutritionally sufficient to give a peak yield of 7.38 × 107 TCID50 ml-1 of OrNV at the 6th day post-infection in attached cultures of DSIR-HA-1179 cells in 25 cm2 T-flasks. Knowledge of the cell line's nutritional demands and virus production kinetics will aid in the formulation of a low-cost culture medium and better process design for large-scale OrNV production in future.

Abstract
The lipid emulsion components of a serum-free insect cell medium were varied and evaluated for effects on cell growth and recombinant protein expression. The growth of High-Five(TM) cells was significantly affected by polyol Pluronic F-68 and Tween-80, but not by lipids. Pluronic was essential for cell growth, while Tween-80 was required to achieve maximum cell densities. A dose response effect was observed for Tween-80 with optimal cell growth at a concentration of 25 mg/l. Cholesterol had a minor effect on cell growth, but was essential for the expression of recombinant proteins. The expression of β-galactosidase (β-gal) was directly affected by cholesterol with optimal expression at a concentration of 5.4 mg/l. Vitamin E, important as an antioxidant to stabilize lipids, did not directly affect recombinant protein expression. Although lipids were not required for cell growth, the presence of lipids were required during the cell growth phase in order to achieve efficient infection with baculovirus. These studies help to define the important components, and range of concentrations, for lipid emulsions which can effectively replace serum in insect cell culture.

Abstract
The increasing interest in products from animal cells has caused an extensive research effort towards development of media for cell cultivation.The basic components in the media used for cultivation of animal cells vary depending upon the characters of the cells and the cultivation method. Basic components consist of an energy source, nitrogen source, vitamins, fats and fatty soluble components, inorganic salts, nucleic acid precursors, antibiotics, oxygen, pH buffering systems, hormones, growth factors and serum. Extensive efforts are directed towards developing serum-free or chemically defined media. Among the serum substitutes is a long list of hormones and growth factors.

Abstract
A fed-batch method was developed which increased the density of insect cells (Spodoptera frugiperda, Sf-9 cells) in suspension culture and the feeding of nutrients improved the yield of a recombinant protein produced by a baculovirus expression system. Analysis of spent medium samples indicated that depletions of glucose and glutamine correlated with the retardation of cell growth. Feeding of a mixture of nutrients consisting of glucose, glutamine, yeastolate and lipids solution restored the growth rate. In fed-batch culture, cell density was increased from 3 x 10(6) cells per ml to 1.2 x 10(7) cells per ml and the increased cell density enhanced the yield of the desired recombinant product, in this case, human nerve growth factor (rhNGF). The optimal conditions for the production of rhNGF were also defined by selecting the appropriate viral multiplicity of infection (MOI). At a cell density of 5 x 10(6) ml-1, a MOI of 0.05 (plaque forming units per cell) gave the highest yield of rhNGF in culture fluid 3 d post-infection. The yield of rhNGF was 20 mg l-1. The fed-batch method was scaled up to 12 l stirred bioreactor.

Abstract
In order to develop a financially feasible process to produce Anticarsia gemmatalis Nuclear Polyhedrosis virus in cell culture, we developed a lipidic supplement to replace fetal calf serum in insect cell culture media. The supplement, prepared with an extract of lipids from hen egg yolk, allowed us to reduce the contents of serum in the culture medium from 10% to 1%. IPLB-Sf-21 cells could be kept along consecutive passages in serum-reduced medium. The replication of AgNPV in HEYLE-supplemented cultures was evaluated. Extracellular virions production was the same as in FCS-supplemented-cultures, but the production level of polyhedral inclusion bodies was significantly lowered in HEYLE-supplemented cultures. The reduced production of PIBs is related to a premature releasing of non-occluded particles as well as to a reduced synthesis of polyhedrin protein.

Abstract
A low protein aqueous lipid supplement (Ex-Cyte VLE), in combination with pluronic polyol, is an effective replacement for fetal bovine serum for insect Sf-9 cells. Serum-free medium with lipid supplement and pluronic (SFM-LP) supported higher cell viability and maximum cell populations than serum-supplemented medium. No adaptation procedures are required when switching cells from serum-containing medium to SFM-LP, and growth rates remain constant during continued passages in SFM-LP. The amounts of recombinant proteins produced, which is the major use for the Sf-9 cells, are better or equal in SFM-LP compared to serum-supplemented medium. SFM-LP also supports growth of the TN-368 cell line but IPLB-SF-21AE or IZD-Mb0503 lines grow poorly in this medium.
