- BIOTEC Bangkok herbarium
One of the major responsibilities to the biodiversity study of Thai fungi is to preserve the specimens collected from natural places around the country. To date, a lot of samples have been deposited in the Mycology Laboratory collections (approximately 20,000 samples). This is now increasing at a rate of about 5,000 samples each year. Such a herbarium is invaluable for Thailand because it stores type and voucher specimens which would otherwise have to be deposited overseas. To qualify as an international herbarium suitable for use by both Thais and foreign mycologists we registered the fungal herbarium collections with the New York Botanical Gardens (NYBG), USA giving the name BIOTEC Bangkok Herbarium with the acronym BBH. Therefore, the Mycology Laboratory now stores the largest collection of insect fungi in Thailand. Our responsibilities are to preserve the good quality of the herbarium, maintain a good collecting system, and develop an appropriate database supporting easy access to the specimens. The specimens have been dried, labeled, mounted, and filed according to widely accepted, international standards. Documentation of these collections is being entered in the computerized database, which is now the primary tool of herbarium management and research.
Fungi play an important role to humans and the environment in both beneficial and harmful ways. The harm they may cause to humans can be in several sectors, including agriculture, industry and medicine, the basic requirements for the identification of fungi are likely to rise accordingly. Due to the taxonomic research, our knowledge of their evolutionary relationships, bioactive compounds and enzyme production, it important to know the identity of the fungus, at least to genus level, to continue their research. Moreover, there are industrial companies that have problems with mold contamination in the production process. It is therefore necessary to identify the fungal contamination to be able to prevent and eliminate it.
Fungal classification and identification in the past are mainly based on morphological features. However, many fungi show similar morphological characters and some fungi do not produce the sexual state on medium. It is impossible to classify and identify the genus and species by morphological techniques only. The use of molecular techniques, biochemistry or other methods are provided to obtain the correct and more reliable identification.
IOTEC Mycology Laboratory usually gives the Identification service to universities and companies. We use both morphological and molecular techniques. Now we have researchers and assistant researchers who are experts in various fields of mycology and have the availability of materials and tools to support in the identification service.
