Biofuels

The microbial conversion of organic matter into biofuels holds potential as a renewable energy source. Among biofuel sources, microalgae are recognized as a highly efficient and adaptable feedstock for biodiesel production, owing to their rapid biomass accumulation, elevated lipid productivity, and capacity to proliferate in diverse aquatic systems, including freshwater, marine, and wastewater habitats. Unlike terrestrial crops, microalgae do not compete for land and can achieve significantly...

Bioplastics

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...

Microbial Bioremediation of Plastics

Polyethylene terephthalate (PET) is a synthetic polymer widely utilized in the packaging industry, particularly for bottles and containers. Due to its chemical stability and durability, PET accumulates in the environment, contributing significantly to plastic pollution. It comprises repeating units of terephthalic acid and ethylene glycol, resulting in a semi-crystalline structure that is resistant to natural degradation processes.A notable breakthrough in plastic biodegradation came with the...
Bioreactor Controls-III01:22

Bioreactor Controls-III

Strain improvement is a foundational strategy in industrial microbiology aimed at maximizing microbial productivity, particularly because natural isolates typically yield commercially valuable products in very low concentrations. Although optimizing the culture medium and environmental conditions can improve yields, these adjustments are inherently limited by the organism’s genetic potential. As a result, the focus shifts toward genetic modifications to enhance biosynthetic capacity. The...

Area of Science:

  • Biomass energy conversion
  • Plant biotechnology
  • Thermochemical processing

Background:

  • Bioenergy is a crucial alternative to fossil fuels.
  • Effective bioenergy relies on matching advanced conversion technologies with optimized biomass feedstocks.
  • Lignocellulosic biomass can be converted via enzymatic or thermochemical pathways.

Purpose of the Study:

  • To review thermochemical conversion pathways for lignocellulosic biomass.
  • To identify biotechnology and breeding targets for improving biomass feedstocks for pyrolysis, gasification, and combustion.
  • To discuss biomass traits relevant to thermochemical conversion, considering both biological and engineering perspectives.

Main Methods:

  • Review of thermochemical conversion pathways.
  • Analysis of biomass traits influencing conversion efficiency (cell wall composition, mineral and moisture content).
  • Discussion of genetic control, environmental influences, and modification consequences for these traits.

Main Results:

  • Biomass traits for thermochemical conversion differ from those for enzymatic conversion.
  • Optimizing lignin levels and reducing ash and moisture content are key for improving feedstocks.
  • Ultimate analysis properties (H:C, O:C, heating value) may be more suitable for high-throughput phenotyping than traditional biochemical analysis.

Conclusions:

  • Improving biomass feedstocks through targeted modifications is essential for efficient bioenergy production.
  • Understanding the genetic and environmental factors influencing biomass composition is critical.
  • This research contributes to global bioenergy utilization and plant adaptation knowledge.
