4 Major Types of Biotechnology
The biotechnology field comprises four main types:
- Red biotechnology: also known as medical biotechnology
- Green biotechnology: focuses on agricultural biotechnology
- Blue biotechnology: another name is marine biotechnology
- White biotechnology: sometimes called industrial biotechnology
1. Red Biotechnology: Advancing Human Health
Red biotechnology involves applying biological approaches to innovating healthcare solutions for preventing, diagnosing, and treating medical conditions.
It encompasses subfields like pharmacogenomics for developing personalized medicines tailored to a patient’s genetic profile as well as regenerative medicine leveraging stem cell therapies to regenerate damaged tissues and organs.
Examples Of Red Biotechnology
Recombinant Insulin
After the insulin gene was cloned in the late 1970s, genetically engineered bacteria were created to produce unlimited quantities of synthetic human insulin to treat diabetes. This replaced earlier insulin extracts from slaughtered livestock, allowing more effective and consistent disease control.
Vaccines
Viral antigens are mass-produced via organisms like bacteria, yeast, or cell cultures instead of growing viruses in eggs or animal tissues. This enables rapid, sterile vaccine production. Examples include the Hepatitis B and human papillomavirus (HPV) vaccines.
Gene Therapies
Diseases caused by genetic abnormalities can potentially be cured by inserting healthy genes into a patient’s cells using modified viruses. In 2019, Zolgensma became the first approved gene therapy for Spinal Muscular Atrophy (SMA), a leading genetic cause of infant death.
Antibiotics Production
The development and mass production of antibiotics, such as penicillin and its derivatives, have been one of the most significant contributions of red biotechnology. These antibiotics have drastically reduced deaths from bacterial infections.
Monoclonal Antibodies
By fusing immune cells with cancer cells, monoclonal antibodies can be engineered to accurately target proteins driving disease while minimizing side effects. For instance, monoclonal antibodies like trastuzumab (Herceptin) successfully treat HER2-positive breast cancers.
Tissue Engineering
Stem cells derived from sources like bone marrow or fat hold promise for growing implantable biological tissues and organs like skin, cartilage, or heart muscle to repair or replace damaged body parts.
By enabling precise disease targeting and individualized treatments, red biotechnology continues advancing healthcare from reactive disease management toward more proactive and personalized medicine focused on optimizing health.
Applications of Red Biotechnology
Red biotechnology drives innovation across disease prevention, diagnosis, and treatment:
Disease Prevention
Vaccines leveraging biotechnology remain the most effective approach for preventing infectious diseases. The HPV vaccine is projected to reduce cervical cancers by 60-90% and already cut pre-cancer diagnoses among teen girls by half. Genetic testing also enables screening embryos or fetuses to evaluate disease risk.
Diagnostics
Biosensors monitor biomarkers like blood glucose to track health conditions. Rapid diagnostic tests quickly identify pathogens like COVID-19 via lateral flow assays without complex equipment. Pharmacogenomics tests predict responses to therapies based on genetic makeup.
Treatment
Biologics like insulin, growth hormones, and antibodies manufactured in cell cultures make up over 40% of new drug approvals by the FDA in 2022. Gene and cell therapies can potentially cure diseases by editing mutations or regenerating tissues using stem cells.
Regenerative Medicine
Stem cells offer a means for regenerating damaged organs by growing healthy specialized cells to treat conditions like heart disease, neurological damage, joint degeneration, and wounded skin. 3D bioprinting also enables constructing organs for transplantation.
Personalized Medicine
By analyzing an individual’s genetic makeup, biomarkers, and microbiomes, healthcare professionals can develop treatments that address specific needs, leading to more effective results. This approach is especially helpful in precision medicine, where genetic testing is used to identify mutations or biomarkers that are linked to certain diseases, and treatment options are customized based on those findings.
Advantages of Red Biotechnology
Extending lifespans
COVID-19 vaccines have already saved over 14.4 million lives globally through late 2022 and routine childhood immunizations save about 4 million lives every year worldwide with measles vaccination alone having the potential to save nearly 19 million lives this decade.
Cancer death rates dropped by 27% from 1991 to 2017 aided by biologics and genomic testing for personalized treatments.
Reducing mortality/morbidity
Monoclonal antibodies cut ICU admissions/deaths among high-risk COVID-19 patients by 70-85%. Gene therapies effectively treat previously fatal childhood conditions.
Improving quality of life
Synthetic growth hormones treat deficiencies improving growth. Insulin analogs enable tighter glycemic control reducing diabetes complications.
Enabling regenerative solutions
Stem cells could eliminate the need for transplants by growing personalized organs from a patient’s cells.
2. Green Biotechnology: Sustainable Agricultural Biotechnology
Green biotechnology focuses on innovating agricultural and environmental products like genetically modified organisms (GMOs) as well as biological processes for eco-friendly manufacturing and remediation.
Examples of Green Biotechnology
Herbicide-Resistant Crops
Soy, corn, cotton, and other crops are genetically engineered to tolerate herbicides that eliminate weeds while leaving crops intact, reducing the need for plowing or toxicity. However, overreliance enabled resistant “superweeds”.
Pest-Resistant Crops
Genetically modified corn and cotton produce their insect toxins by inserting Bacillus thuringiensis (Bt) bacterial genes. This allowed farmers to grow crops that kill pests trying to eat them while remaining safe for people.
However, some insects are now evolving resistance to the toxins, enabling them to withstand and feed on genetically engineered crops
Drought-Tolerant Crops
Various projects aim to engineer drought-resistant cereal crops like wheat, rice, and maize containing genes enabling improved water retention and heat tolerance mechanisms to maintain yields despite climate change pressures.
Applications of Green Biotechnology
Key applications driving growth in the green biotechnology market, projected to reach $66.6 billion by 2026, include:
Agriculture
GMOs protect crops despite reduced cultivation and chemical uses, thereby improving yields along with pesticide and water use efficiency compared to traditional techniques.
Food Production
Biofortified crops with improved nutritional profiles provide affordable access to key micronutrients like Vitamin A, iron, and zinc to combat malnutrition globally.
Biofuels
Using crops like corn and soybeans or inedible cellulosic biomass feedstocks like grass and wood wastes, industrial biotech converts plant sugars into renewable gasoline substitutes like ethanol and biodiesel fuels.
Bioremediation and Biosensing
Microbes or plants naturally absorb toxins from soil or water enabling low-cost environmental cleanup. Biosensors also aid real-time ecosystem monitoring.
Advantages of Green Biotechnology
There are several benefits to green and agricultural biotechnology including:
Increased Food Production
Between 1996 and 2018, genetically modified (GM) crops increased crop yields by 15% or more while raising farmers’ profits by 68% and preventing deforestation from expanded farmland needs. Biofortified crops also combat malnutrition.
Pesticide Reduction
GM insect-resistant (IR) crops reduced insecticide use by 8% (775 million kg) from 1996–2018. However, the impact of GM herbicide-tolerant (HT) crops on herbicide use is mixed, with estimates ranging from a 13 million kg decrease to a 239 million kg increase over the same period.
Climate Resilience
Drought-tolerant maize varieties, tested in 13 African countries, show 20-30% higher yields than regular ones, even under drought stress. With climate change estimated to cause a 10-30% decline in Africa’s maize yields by 2030, these varieties offer a crucial solution. Additionally, projected wheat losses in South Africa under warming scenarios could be reduced by adopting drought-tolerant strains.
Renewable Biofuels
Converting corn and soybeans or non-food plants into ethanol and biodiesel reduces reliance on finite fossil fuels.
