“…Chooklin et al (2011) reported the total sugars for oil palm sap were 19.17 g/L or 1.92% (w/v) and comprised only glucose (1.66%) and fructose (0.26%). In a separate study, saps from oil palm trunk were reported to have 11% total sugars (Eze and Ogan 1988). Goh et al (2013) reported sawdust extracted from oil palm and coconut trunks contained approximately 2.77% and 21.2% w/w total sugars, respectively.…”

The influence of different medium components (glucose, sucrose, and fructose) on the growth of different Ganoderma isolates and species was investigated using mixture design. Ten sugar combinations based on three simple sugars were generated with two different concentrations, namely 3.3% and 16.7%, which represented low and high sugar levels, respectively. The media were adjusted to either pH 5 or 8. Ganoderma isolates (two G. boninense from oil palm, one Ganoderma species from coconut palm, G. lingzhi, and G. australe from tower tree) grew faster at pH 8. Ganoderma lingzhi proliferated at the slowest rate compared to all other tested Ganoderma species in all the media studied. However, G. boninense isolates grew the fastest. Different Ganoderma species were found to have different sugar preferences. This study illustrated that the mixture design can be used to determine the optimal combinations of sugar or other nutrient/chemical components of media for fungal growth.

“…Aliquots were applied to cellulose TLC plates and developed in a solvent mixture of isopropyl alcohol/pyridine/water/acetic acid (8:8:4:1 by volume) (Matsui 1970). The plates were air dried and spots were visualized by spraying the plate with a solution containing aniline (1 mL), diphenylamine (1 g in 10 mL distilled water), and phosphoric acid (100 ml) (Eze and Ogan 1988). The plates were heated at 120°C for 10 min.…”

A comparison of the morpho-cytology and chemical composition of the two forms of the cyanobacterium, Nostoc commune Vauch., from the Philippines and Japan

Nostoc commune Vauch. is one of the few freshwater cyanobacteria that has been used as human food. But its commercial production has been elusive. This prompted us to investigate further on the chemical composition and morpho-cytological characteristics of the discoid and spherical forms of the alga from the Philippines and Japan. Light microscopy of the two forms revealed that they consisted of irregularly coiled, unbranched, heterocystous filaments. Transmission electron microscopy showed that a trichome was enclosed by a 14μm thick mucilaginous sheath (extracellular polysaccharide, EPS). A colonial sheath enveloped a spherical colony that was made up of a bluegreen outer core that enclosed an inner, whitish, fleshy core, while the discoid form was a deflated or desiccated form of the spherical form. Cytologically, the outer core of the spherical colony (PS) had significantly (p<0.01) shorter filaments and higher heterocyst frequency than the discoid colony while the discoid type had greater number of detached heterocysts than the other type. Chemical analyses revealed that the cyanobacterium had 34-45% oxalate-oxalic acid soluble substances (OOSS), a dietary fiber that was found to be in higher concentration among the discoid forms than the spherical forms. The major components of OOSS were identified as glucuronic and galacturonic acids that may play a role in modulating water flow in the glycans of the mucilaginous sheath. There were 17 amino acids identified. Philippine spherical (PS) colonies yielded generally higher concentration for each of these amino acids than the discoid types (PD and JD) except for phenylalanine, aspartic acid, and proline. There were six soluble proteins identified in the samples with the following molecular weights in kDa: 73, 55, 39, 36, 29, and 14.4. A protein band of 55 kDa was common to all types of colonies while 73 kDa was identified in the spherical form (PS) and faintly in the discoid form (JD). The protein bands of 39, 36, 29, and 14.4 kDa were found distinctly among the discoid forms (desiccated types) regardless of origin but absent in the spherical forms. In vitro protein digestion was improved, by as much as 30%, when the pigments were extracted. However, the presence of phenolic compounds could also affect protein digestion. Morpho-cytological studies and chemical analyses showed that N. commune of the same colony form generally had the same characteristics regardless of their origin. Although the common traits were more obviously observed among the discoid colonies. However, protein, crude lipid, and chlorophyll a concentrations were found to be more dependent on the age and culture condition of the cyanobacterium than on colony form or origin.

“…It should be noticed that the oil palm (Elaeis guinensis) also contains around 10% sucrose 12 and thus can be considered as a source of fermentable sugar.…”
