Wild type species of Mentha was assayed in vitro for salinity (NaCl) tolerance. Micro propagated subcultured stem of Mentha was used to assay shoot length, multi shooting, root length, root number, and the emergence of leaves. Different concentration of NaCl (0.1 mg/ml, 0.2 mg/ml, 0.3 mg/ml and 0.4 mg/ml) supplemented in MS media was used for different treatments. Data was recorded after various periods (7 days, 14 days, 21 days, and 28 days) of time. The study reveal that shoot length increases favourably at low concentration of NaCl (0.1 mg/ml and 0.2 mg/ml) but at higher concentration (0.3mg/ml and 0.4 mg/ml) there is a reduction in length. Number of emerged shoots increases during every treatment. The number, however, gets inhibited at 0.4mg/ml of NaCl. NaCl's concentration (except 0.4 mg/ml, which completely inhibits emergence) seems to favor the emergence of roots. The number seems to be the greatest at 0.3 mg/ml of NaCl. Every concentration of NaCl except for 0.4 mg/ml (which completely inhibits the growth) inhibits the root length. Every concentration of NaCl has been found to favour the emergence of leaf in the propagated plantlet. A concentration of 0.3 mg/ml has been found to initiate the emergence of leaves the fastest. The emergence of leaves could also be noticed at 0.3 mg/ml and 0.4 mg/ml even after 21 days of incubation. The finding mentioned above can be useful in future research on micropropagation. The details of each finding is described.

A series of laboratory and green house experiments were conducted to investigate the efficacy of Trichoderma harzianum fungi, bacteria ( Flavobacterium, Bacillus megatherium var. phosphaticum (BMP) and Azomonas ) on Striga hermonthica early developmental stages , incidence and sorghum growth under laboratory and greenhouse conditions. The first laboratory experiment results showed that application of BMP + Flavobacterium significantly inhibited S. hermonthica seeds germination during and after conditioning in response to GR24 concentrations as compared to medium control. In the second laboratory experiment, application of the filtrate of T. harzianum alone or in combinations with bacteria significantly inhibited S. hermonthica germination and haustorium initiation as compared to the corresponding control. From greenhouse experiment results, S. hermonthica emergence significantly reduced by T. harzianum and insignificantly by the combination of Flavobacterium + BMP + T. harzianum . T. harzianum followed by the combination of Flavobacterium + BMP gave the highest increment in plant height. T. harzianum significantly increased sorghum number of leaves as compared to the infested control. The combination of Flavobacterium + BMP + T. harzianum gave the highest number of leaves. The combination Flavobacterium + BMP gave the highest sorghum shoot dry weight, followed by T. harzianum . While the highest sorghum root dry weight was obtained from the combination of Flavobacterium + BMP + T. harzianum . Generally, the combination of T. harzianum + Flavobacterium + BMP reduced S. hermonthica infestation and enhanced sorghum growth in comparison to the infested control.
在室内和温室条件下，研究了哈茨木霉真菌、细菌(黄杆菌、大芽孢杆菌和偶氮单胞菌)对褐刺菌早期发育阶段、发病率和高粱生长的影响。第一次室内实验结果表明，与培养基对照相比，BMP + Flavobacterium的应用显著抑制了GR24浓度对S. hermonthica种子萌发的影响。在第二个实验室实验中，与对照相比，单独施用哈茨芽孢杆菌滤液或与细菌联合施用可显著抑制hermonthica的萌发和吸器形成。从温室试验结果来看，哈兹菌显著降低了红月牙曲霉的出苗率，而黄杆菌+ BMP +哈兹菌组合的出苗率不显著。黄杆菌+ BMP组合的植株高度增幅最大，其次为哈兹兰。与对照相比，哈兹菌显著增加了高粱的叶片数量。黄杆菌+ BMP + T. harzianum组合的叶片数量最多。黄杆菌+ BMP组合的高粱茎部干重最高，其次是哈兹芽孢杆菌。而黄杆菌+ BMP + T. harzianum组合的高粱根干重最高。一般来说，与受侵染的对照相比，哈氏霉菌+黄杆菌+ BMP的组合减少了hermonthica的侵染，促进了高粱的生长。

The rhizospheric soil samples of Nongkhyllem Reserve Forest, Nongpoh, Meghalaya were screened for endomycorrhizal qualitative and quantitative analysis. Hyphal infection/colonization was present in all rhizospheric soil samples, whereas vesicular infection was found scarce and absent in most of the rhizospheric samples. It is observed that scrubs, herbs, and shrubs had high p H values than trees. Percent total colonization in roots was also low in scrubs and trees than herbs and shrubs whereas climbers were having high total endomycorrhizal colonization in roots. Shrubs and trees were having more AM spore numbers than scrubs. Percent colonization intensity and percent hyphal infection in roots in case of herbs, shrubs and climbers were high than trees and scrubs. Percent vesicular infection was also low in trees and shrubs than herbs. Percent arbuscular infection was again low in case of scrubs and trees than shrubs, herbs and climbers but trees were having more percent organic carbon than shrubs, herbs and climbers. The soil temperature in scrubs and trees was high than shrubs, climbers and herbs. But AM spore numbers increased with elevation. Total root colonization (%), hyphal infection (%), arbuscular infection (%) and colonization intensity (%) gradually decreased with elevation. At lowest elevation the organic carbon (%) was low. There was no any significant change in p H value, but little fluctuation was reported with elevation and it occurred in acidic range. The diversity index of Umtasor range was 0.036 and that of Nongpoh range was 0.049. The correlation coefficient (r) between species richness and diversity index was 0.54 (positive correlation) and it suggests that species richness is positively correlated with diversity index in the reserve forest.

L-asparaginase is an important enzyme, which plays a significant role in the treatment of acute lymphoblastic leukemia, acute myelocytic leukemia, and other carcinoma treatments. It is well known as an anti-cancerous agent because of its stability in varied environmental conditions. Streptomyces sp. is occupied the first position for the producing L-asparaginase from marine and terrestrial sources. In the presence of L-asparaginase, tumor cells get deprived and can’t endure. It acts as a potent antitumor or anti-leukemic drug. Because of the urgent need, an attempt was made for isolation and optimization of marine actinomycetes for the production of L-asparaginase. S. krainskii VMB-11 was isolated and inoculated in optimized M-9 media at 40 ° C, 96 h improve the production of L-asparaginase from 8.2 IU to 13.2 IU/g dry wt.of biomass. To the simplest of our data, this is often the primary report on production, purification, and characterization of L-asparaginase from marine Streptomyces isolate VMB-11 strain.

This research was aimed to isolate cellulolytic fungi showing hyper-cellulase activity. Potential cellulase-producing fungi were isolated from different soil samples, particularly near agro-wastes dumping sites. Among the various isolates obtained from different sampling sites, three different fungi were selected depending upon the clear zone diameter produced in Carboxymethyl Cellulose (CMC) agar. CMC hydrolysis by all three fungal strains exhibited their activities at pH 5.5-7.5, whereas maximum activity occurred at pH 5.5. Enzymes were also pH stable. Based on K m and V max values, the endoglucanase and β-glucosidase enzymes of Aspergillus niger were most efficient. The characterization of these fungi may also provide an opportunity to screen the cellulase enzymes for their further utilization in bio-ethanol production using lignocellulosic agro-wastes.

This study was conducted to document the bryophyte species composition, and the effects of different environmental factors at the University of the Philippines-Diliman, a campus in an urban area. A total of 11 species of bryophytes were identified which includes nine species of mosses and two species of liverworts. Among the species observed, Hyophila involuta (Hook.) A. Jaeger and Taxithelium instratum (Brid.) Broth. were found to be widely distributed across sites. On the other hand, Meiothecium microcarpum, Cyathodium foetidissimum Schiffn. and Vesicularia montagnei (Bel.) were rarely found. Species composition is relatively small compared to the previous surveys conducted in high altitude and moist environments. It was suggested that aside from habitats, other factors such as current disturbance events and the presence of specific tree species may contribute more to the bryophyte species composition in the University of the Philippines-Diliman campus.
