The more competitively aggressive clones could optimize their productivity when planted in sites with high residual levels, reaching productivities similar to those of homogeneous stands.
Consortial H. boliviensis accumulate up to 31% of their dry-weight as PHB, reaching productivities up to 28.3 mg PHB L−1 d−1.
Trees can begin producing nuts in about five years (two or three years shorter than pistachios) and reach peak productivity at about 10 years, which tapers off to almost nothing by age 25 or so.
Managed grasslands and forests reach highest productivity and volumes at low diversity.
As a consequence, stands recovering from intensive management would need at least two stand-replacing events (400 years) to reach a productivity status similar to non-managed stands.
An additional benefit from training apprentices can be measured by saved future recruitment costs (Stevens 1994b), i.e., the costs a firm faces when searching for and training workers from the external labour market until they reach full productivity.
The great differential of the Brazilian forest industrial sector is the wood, produced at low costs and with elevated quality in the country, especially Eucalyptus, which in some areas can reach a productivity of up to 100 m3/ha · year.
In order to meet the increasing demand for high-quality miniature parts made of a wide variety of materials, the electronics, biomedical and optical industries are moving towards micro/nano-machining. Currently, mechanical micromachining can only be performed under very low feed rates and small depth of cut, which makes it very difficult to reach reasonable productivity.
The expression of β-glucosidase in the culture medium has been reported to reach the productivity of 0.3 mg/mL and the maximum activity was reported as 60 U/mL.
To reach maximal productivities, the growth conditions could be further optimized; the growth period could be extended to reach higher cell densities, and effects of growing the cells mixotrophically with addition of glucose could be investigated.
