Biomass Resources

Lignocellulosic biomass resources are renewable materials that can be converted to fermentable sugars and subsequently into ethanol. Water hyacinth (Eichhornia crassipes) is a cellulosic aquatic plant that has high carbohydrates, low lignin content, and notable reducing sugars content in its structure. Based on the literature review in the case of water hyacinth, the most frequently used pretreatment methods were acid and alkali, while ionic liquid and microwave-assisted methods were used rarely. The dominant sugars were glucose, xylose, galactose, arabinose, and mannose. Based on the findings, cellulase and S. cerevisiae were mostly used for enzymatic hydrolysis and fermentation of water hyacinth to ethanol, respectively. This review presents the recent studies in pretreatment, hydrolysis, and fermentation of water hyacinth biomass into ethanol.

Abstract E. crassipes, a native of South America, is a major freshwater weed in most of the frost-free regions of the world and is generally regarded as the most troublesome aquatic plant (Holm et al., 1997). It has been widely planted as a water ornamental around the world because of its striking flowers. Wherever it has encountered suitable environmental conditions it has spread with phenomenal rapidity to form vast monotypic stands in lakes, rivers and rice paddy fields. Then it adversely affects human activities (fishing, water transport) and biodiversity. It is impossible to eradicate, and often only an integrated management strategy, inclusive of biological control, can provide a long-term solution to this pest.

Seedling Leaf

We tested several plants for the occurrence of unusual polyamines such as homospermidine, aminopropylhomospermidine, norspermidine, norspermine, thermospermine, and caldopentamine. The leaf and root of aquatic plants ubiquitously contained homospermidine in addition to usual polyamines such as putrescine, spermidine, spermine, and cadaverine. Homospermidine was widely distributed in the seed, seedling, leaf, and root of gramineous plants such as rice, millet, oat, rye, wheat, barley, corn, sorghum, and timothy as a minor polyamine. Aminopropylhomospermidine was found in the two aquatic plants, the water lily Nymphaca tetragona and the lotus Nelumbo nucifera as a major polyamine, and in the gramineous seeds as a minor polyamine. Norspermidine, norspermine, homospermine, and caldopentamine were detected in two floating aquatic plants, the duckweed Spirodela polyrhiza and the water hyacinth Eichhornia crassipes. Thermospermine was sporadically detected in some aquatic plants and gramineous seeds. Key words: Gramineae, aquatic plant, polyamine, homospermidine, caldopentamine.

Three Egyptian species of the oribatid mite family Malaconothridae, all found on roots of the floating aquatic plant Eichhornia crassipes in the River Nile, are analyzed. Trimalaconothrus crassipes Ramadan, Ismail & Mustafa, 2017 is recombined to Tyrphonothrus crassipes (Ramadan, Ismail & Mustafa, 2017) (comb. nov.). Malaconothrus ramadani Ramadan, Ismail & Mustafa, 2018 and M. transversus Ramadan, Ismail & Mustafa, 2018 are both considered to be tritonymphs of Ty. crassipes (=M. ramadani syn. nov.; =M. transversus syn. nov.).

Negative Impacts

Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.
